   The Method Debate
Seamless O-O Software Architectures
   Kim Walden & Jean-Marc Nerson

    Level: intermediate (MM1)
    O-O analysis techniques can be used to create  a  high-
    level  architecture  for an application, which directly
    models  the   problem   domain   and  allows   seamless  
    transition  to  implementation in an  O-O  language. In
    contrast to  other  approaches, no  paradigm  shift  is 
    involved; the  same  O-O  abstraction  principles apply 
    throughout. The  tutorial gives an  overview  of BON, a 
    method  comprising  a  set of  guidelines and notations 
    for  O-O  analysis  and  design, drawn  from  practical  
    experience  and  directly   targeted  at   reusability.
    It also reviews existing O-O  techniques  and  compares 
    them with  BON.  A small case study  is used to explain 
    the successive methodological steps.

Smalltalk Essentials
  Trevor Hopkins

     Level: intermediate (MM2)

     This talk introduces Smalltalk for those already  adept
     in  another  object-oriented  language. Basic Smalltalk
     features  are  covered  fully  and  rapidly,  and  more
     `advanced'   capabilities   considered.   Smalltalk  is
     presented as an integrated  language  and  environment,
     with a pure O-O language model. The  following   topics 
     are covered. Language  and  library  issues: collection 
     and  GUI  classes,  metaclasses,  exception   handling, 
     environment: compiler, workspaces, browser, inspectors,
     debugger,  Multi-person  development.  Metaprogramming:  
     identity-changing  primitives, dynamic  class-changing 
     methods.  Concurrency:   processes   and   semaphores, 
     concurrency   classes,   recursion-safe  locking   and
     concurrency-safe data structures.

     Trevor Hopkins is a Senior Lecturer in Computer Science
     at the University of Manchester. His research interests
     include O-O design quality analysis,  automatic  design
     transformation,  language implementation techniques and
     concurrent   object   programming. He   has also   been 
     introducing O-O development to many companies.

Running an O-O RAD Workshop
  Ian Graham

     Level: intermediate (MM3)

     This tutorial will explain the SOMA approach to  system
     development in outline, concentrating on its use of O-O
     RAD workshops for  requirements  capture  and  business
     process reengineering. Participants  will  learn how to
     organize and facilitate such a workshop  and  have  the
     chance  to  walk  through  a  simple  example set as an
     exercise.  Agenda:  The  basics  of  O-O  analysis  and
     object   modeling  using  SOMA.  Running  an  O-O  RAD.
     Requirements  capture  and  the  Task   Object   Model.
     Transforming the Task Object Model to a Business Object
     Model. Hands on simulation using class cards  to  debug
     the  specification.  Building  an event trace. The non-
     procedural life cycle model.

     Ian Graham is a specialist in  object  technology  with
     Swiss  Bank Corporation. He contributes regular columns
     to Object Magazine and Report on  Object  Analysis  and
     Design. His SOMA (Semantic  Object  Modeling  Approach)  
     is described in  outline in his  book ``Object-Oriented 
     Methods''  and  in  full  in  the  recently   published
     ``Migrating to Object Technology'' (both Addison-Wesley).

Large O-O projects in C++
  Nguyen Thuy

     Level: intermediate (MM4)

     This tutorial shows how objects can  be  used  in  real
     life   systems  to  address  key  software  engineering
     issues. It will first present some key  issues  in  the
     design  and the implementation of large object oriented
     software systems: tests, maintenance,  perenniality  of
     persistent  data,  reuse,  productivity  of development
     teams. It will underline some of the dangers of a naive
     usage  of  the object oriented approach with respect to
     these issues, and the consequent risks for the  success
     of  large  projects.  Architectural,  design  and  test 
     principles  addressing  these  issues   will  then   be 
     given. Examples in C++ will demonstrate that one of the 
     real interest  of  the  object  oriented approach is to 
     provide   extremely   elegant   mechanisms   for    the
     implementation of these principles.

Object-based languages for distributed  systems:  Towards  a
  Rachid Guerraoui

     Level: intermediate (MM5)

     There has recently been a great interest in  using  O-O
     concepts  for distributed systems.  One major reason is
     the adequation of encapsulation and  object  invocation
     paradigms.   Consequently,  many object-based languages
     have been designed with distribution  in  mind.  For  a
     better understanding and evaluation of these languages,
     this  tutorial  proposes  a  classification  based   on      
     different  aspects   such as  concurrency expressivity, 
     concurrency control, handling of failures, and  objects
     placement.   Various design alternatives are presented:
     active vs. passive objects, synchronous  vs.  asynchro-
     nous  invocations,  internal  vs.  external concurrency
     control, independent vs. dependent concurrency control,
     atomic   vs.  non  atomic  invocations,  implicit  vs. 
     explicit objects placement, etc. All the  alternatives 
     are   discussed  using   examples  and  are  evaluated 
     according to criteria such as flexibility,  simplicity 
     and  modularity.

     Rachid Guerraoui is member of the Operating Systems Lab
     at   the   Computer    Science  Department   of   Ecole
     Polytechnique   Federale  de   Lausanne.  His  research 
     interests include distributed systems, fault-tolerance, 
     and object-oriented programming.

The Fusion method
  Paul Jeremaes

     Level: intermediate (MA1)

     This tutorial  provides attendees with  an introduction
     to the Fusion O-O development method. The method builds 
     on early,  first generation,  methods (e.g. Booch, OMT,  
     CRC,  and  Objectory) and provides a direct  route from 
     requirements definition through to programming language   
     implementation. Fusion was launched  by Hewlett-Packard 
     in 1992  and  is  currently  being  used  worldwide  by  
     projects both inside and outside of HP; it is supported
     by 3rd party CASE tool vendors.

     Paul Jeremaes is a researcher at HP  Laboratories.  His
     research  over  the  past  10  years has focused on the
     development  of  software  engineering  methods  and on
     formal specification techniques. Prior to joining HP he
     worked in the telecommunications industry as a lecturer
     in  software  engineering.  For the past 2 years he has
     been  a   member   of  the  O-O  methods  research  and 
     consultancy  team  and is one of the developers  of the
     Fusion   method.   He  co-authored    ``Object-Oriented 
     Development, The Fusion Method'' (Prentice-Hall, 1994).

Class Interface Design and Programming by Contract
  James McKim

     Level: intermediate (MA2)

     Programming  by  contract  (PBC)  is  a  form  of   O-O
     programming popularized by Bertrand Meyer in his  book, 
     "Object-Oriented  Software  Construction". The    ideas 
     embodied in PBC  result in simpler and shorter code and 
     is flexible enough  to  be  of  great assistance in the 
     specification, documentation,   and   verification   of  
     features  and classes. The  presentation  will  address  
     the following questions: What are the goals and benefits
     of PBC and what is the effect on class interface design?  
     Must  commands  (state changers)  be   separated   from  
     queries (state  accessors)  and  is  there a difference
     between the kinds of  assertions that may be applied to 
     commands  as   opposed   to   queries? What   kind   of  
     information should  be   contained   in  an  invariant? 
     What improvements/ additions to PBC will we see in  the
     next few years? Examples  will  be  taken  from several  
     Eiffel vendors' libraries  as  well  as  from   working
     Eiffel systems.

     research  interests  include O-O programming and design
     in  general, and  class  interface   specification   in 

The ODMG Standard for Object Database Systems
  Francois Bancilhon

     Level: intermediate (MA3)

     Object database systems (ODBS) have been  available for
     more  than 4 years  and have  reached a  clear level of
     maturity.  There is  quite  an  abundant  offer  mainly
     driven  by  the  needs  of  systems  such as CAD, CASE,
     Office Information Systems and any system  storing  and
     manipulating complex or multimedia data that can evolve
     gracefully, and deliver high-performance in the manipu-
     lation   of   complex   structured   data.  Traditional
     business-type  applications   such   as   finance   and
     insurance are now showing interest for this technology.  
     The  tutorial  covers  the  following  topics:  current  
     state  of database technology and relationship  between 
     database   and   programming   technology.   Underlying 
     concepts: the mandatory rules from the "ODB Manifesto".  
     ODMG 93,  standard  proposed  by  the  Object  Database 
     Management  Group:  data  model, ODL  data   definition 
     language and OQL query language, language  bindings for 
     C++ and Smalltalk. Benchmarks, market and applications.

The O-O approach: a practical way to improve reuse
  Annie Kuntzmann-Combelles

     Level: introductory (MA4)

     O-O programming languages have bought a  bunch  of  new
     concepts in software engineering, and somehow one could
     consider this as a revolution of culture.  With  a  new
     and  powerful  paradigm,  we can expect to solve simple
     problems as well as  complex  projects.   The  tutorial
     explains  which  OOPL  concepts are useful in a general
     O-O approach and  which  ones  are  more  dedicated  to
     object  reuse.   Based  on real experiences achieved in
     various application domains,  the  presentation  illus-
     trates  the basic principles of how to efficiently make
     reuse happen. It includes the description of a measure-
     ment  framework  to analyze the ROI of the reuse policy
     and an O-O development process emphasizing reusability.

     Annie Kuntzmann-Combelles is  Executive  Vice-President
     of  Objectif  Technologie  and  consultant for software
     engineering strategies and methods. From 1985  to  1989
     she  was  head of Software Engineering and Applications
     Division at CISI Ingenierie.  She is chairperson of the

O-O Design for Real-Time Systems
   Reinhard Budde & Karl-Heinz Sylla

     Level: intermediate (MA5)

     Real-time systems embedded into larger applications are
     reactive:  they  are  stimulated by signals coming from
     the environment and give feedback to that  environment.
     The basic O-O properties such as encapsulation, inheri-
     tance, polymorphism and contracting are needed to  hide
     hardware/software   design  decisions,  to  master  the
     development of variants, to achieve maintainable, flex-
     ible  systems  architectures,  and  to prove properties
     enabling the compliance to specified reaction times.
     After reviewing existing approaches ranging from system
     dynamics  to  reactive O-O systems, a classification of
     real-time systems into  preemptive  and  non-preemptive
     characteristics  is  discussed  using an O-O framework.
     The framework combines perfect synchronizations (as  in
     Esterel,  Argos, or Statecharts) with the O-O paradigm.
     It is based on Eiffel-like  descriptions.  Classes  are
     augmented  by a behavior-description and inheritance is
     combined with compatible behavior.  The system executes
     time-critical  objects  in parallel. Reaction times are
     obtained by worst-case bottom-up calculations and  used
     for prescheduling the time-critical parts. Medium-sized
     industrial control  applications  demonstrate  how  the
     approach works in practice.

     Reinhard Budde is a computer scientist  at  the  German
     National  Research Center for Computer Science and head
     of a project, in which an integration of O-O  and  syn-
     chronous  languages  for  reactive  systems is investi-

     Karl-Heinz Sylla is a computer scientist at the  German
     National  Research  Center for Computer Science. He has
     substantial experience with programming  languages  and
     development  systems  and  has been responsible for the
     design and implementation of large scale O-O systems.

Object-Orientation: the KISS Method
  Gerald Kristen

     Level: intermediate (TM1)

     This tutorial addresses the  basic  principles  of  the
     KISS  method  for  Object  Orientation.  The   modeling 
     principles  of  the  KISS  method  are  based  upon the 
     grammar of communication with the  natural  language we 
     use every  day. In  the  tutorial  the  attendees  will  
     apply  the modeling  techniques of the KISS method in a 
     real  world  case  with  the KISS-DOMINO  game and will 
     experience  how the different model-types validate each 
     other   with   formal  rules.  Finally   the   tutorial  
     demonstrates  how  the  O-O   models  are   transformed  
     directly  into  a  running information  system  for any 
     implementation environment.

     Gerald Kristen is general manager  of  KISS  in  Veghel
     (The  Netherlands),  a  consulting firm specializing in
     object  orientation.  He  is  the  author of   ``Object  
     Orientation,  the   KISS  method.  From     Information 
     Architecture to Information System'' (Addison Wesley).

Software contracting: the future
  Richard Mitchell & Ian Maung

     Level: intermediate (TM2)

     Strongly-typed programming languages were a significant
     improvement  on  their predecessors for the engineering
     of software-driven systems. Software contracting is set
     to  provide  an equally significant leap along the road
     towards reliable software.  Eiffel has given the  world
     an   effective   programming   language  that  supports
     software  contracting  at  the  design  and programming 
     levels, and other languages are following suit. Eiffel,
     has only started the ball rolling, and there is more to  
     come.   Software  contracting  can be greatly enhanced, 
     and  support  for  the  enhancements   would    require 
     only modest changes to  the Eiffel and  to  its vendors 
     run-time  systems.  The  aim  of  this  tutorial is  to  
     present  the  kinds  of  enhancements that research has 
     now shown to be possible, and to propose directions for
     change in  languages that support software contracting.   
     The  enhancements  fall  into  two  kinds:  those  that  
     deliver better run-time checking of existing contracts, 
     and those  that  allow  new  forms  of  contract  to be  
     expressed and checked.

     Richard  Mitchell  heads   the   Software   Engineering
     Research  Group  in  the Department of Computing at the
     University of Brighton. His research interests  are  in
     literate   software  development  and  its  application
     within formal and O-O methods.

     Ian Maung is a Research Fellow  in  the  Department  of
     Computing  at  the University of Brighton. His research
     interests are in the formal  aspects  of  O-O  software
     development,  including  the  use  of formal methods in
     software development.

Object-Orientation and  Structured  Techniques:  Where  they
overlap; where they conflict.
  Meilir Page-Jones

     Level: beginner (TM3)

     O-O has been termed a revolution. But how much does  it
     overturn  the  principles  of Software Engineering that
     were successful in the 1970s and 1980s?  Although  some
     radicals  answer "completely" and some dinosaurs answer
     "not at all", the  truth  probably  lies  somewhere  in
     between.   How  does  the  structure  of  an O-O system
     differ from that of traditional systems?   Is  there  a
     notation  for depicting  O-O systems that is compatible
     with traditional systems? Does O-O allow us to dispense
     with  analysis  and  design?  Some other issues will be 
     explored in  the  tutorial.   Partitioning: O-O  versus  
     events. Coupling and cohesion: are they still relevant?  
     CASE tool requirements. Top-down or bottom-up?  Demands 
     imposed by reusability.

     Design patterns recently emerged as a glimmer  of  hope
     on the horizon for supporting the development and reuse
     of O-O software systems. They represent a complementary
     enhancement  of existing O-O analysis and design (OOAD)
     methods.  This tutorial gives a  detailed  overview  of
     state-of-the-art  design  pattern  approaches.  A  case
     study exemplifies how they allow to capture and
     communicate   the   design  of  O-O  software  systems. 
     The  tutorial  discusses the role of design patterns as
     means for augmenting existing OOAD methods in order  to 
     significantly improve reusability.  Participants should  
     be  familiar with basic concepts of the O-O programming

Object Strategies for Client/Server Systems
  Sanjiv Gossain

     Level: intermediate (TM5)

     The message-passing paradigm of objects fits in  excep-
     tionally   well   with   the   distributed   nature  of
     client/server systems. However,  client/server  systems
     pose   a  challenge  for  existing  object  development
     strategies,  especially  in their need for concurrency,  
     distribution,  and   asynchronous   messaging.  Current 
     O-O methods  are  rich in notation and description, but  
     weak  in process and heuristics. They do not adequately
     address  the  design  of  systems  that must operate in 
     distributed environments. The tutorial introduces a set
     of  object  development  strategies  found  useful   in
     developing   client/server   systems.   The  discussion
     addresses the compatibility between O-O technology  and
     client/server  systems.  Techniques  for  partitioning,
     taking   advantage  of  distribution  and  concurrency,
     utilizing  asynchronous  message  passing  to  the full
     are described with examples.

     Technology   Partners  (UK),   a  global  client/server
     consulting firm. Dr. Gossain  has been  involved in the 
     successful  deployment  of  a number of O-O systems  in 
     a  broad  range  of  application  areas in the USA  and  
     Europe. He has  been   involved  in  object  technology  
     for  more than 8 years.

O-O  Application  Development:  Class  Relation  Method  and
  Philippe Desfray

     Level: intermediate (TA1)

     The Class-Relation  method  was specifically   designed
     for  O-O  development  in 1990.  The  newly  introduced
     hypergenericity   concept   addresses   the   following  
     challenges.  How  to   formalize   and   systemize  the 
     transition from analysis to  design, how  to  implement 
     and automate the development process from specification  
     through final coding, and how  to  set up  a  technical  
     expertise   thesaurus. The   tutorial   is   aimed   at
     practitioners of O-O methods such as Booch, OOA, OMT... 
     It  provides  solutions  to  complexity  control issues
     raised  during  the development of large-scale software
     systems. After an overview  presentation of  the  Class 
     Relation   Method,   hypergenericity    principles  are
     discussed,  followed  by   generalization   techniques.
     Reviewed   case   studies   deal   with     man/machine
     interface  modeling, model transformation  for  client/
     server   applications,    and    relational    database       
     implementation   of  O-O analysis. The  control of  the 
     development process  is  also  discussed.

Precise Object Modeling
  John Daniels

     Level: intermediate (TA2)

     Although diagrams are by far the most  popular  way  to
     represent  the  results  of  analysis  and design, they 
     frequently  lack  precision and expressive  power,  and  
     are often supplemented by natural language annotations. 
     On the other hand, formal methods  based  on mathematical
     logic  convey  a  precise  meaning,  but can be hard to
     understand. Syntropy  is  a  second-generation  object-
     oriented  analysis and design method which combines the
     diagrammatic power of popular first-generation methods,
     such as OMT, with the additional rigour and consistency
     of formal methods like Z. This tutorial,  intended  for
     practising  software  developers,  will describe how to
     use Syntropy to produce precise object models.

     John Daniels is Director of  Object  Designers  Ltd,  a
     UK-based  consultancy  practice specializing in object-
     oriented  methods.  He  has  practised  object-oriented
     software  development  for  many years. He is co-author

     The tutorial  presents the current  state  of the  OMG 
     specifications.  OMG Object  Model  and  Architecture; 
     Common  Object Request Broker Architecture  (including 
     Interface  Definition  Language,  IDL  to  C  and  C++  
     mapping, Interface  Repository  and Interoperability); 
     Common Object  Services (including Naming, Life Cycle, 
     Events,   Persistence,   Concurrency,   Relationships,
     Transactions,    Security,    Externalization,  Query,
     Properties,   Licensing);   Common   Facilities    and  
     Business Objects. Main OMG compliant existing products 
     (as  IBM  DSOM, IONA ORBIX,  SunSoft  DOE)  are   also 
     presented  and  relationships  with  other  Models and 
     Architectures  (as  PCTE, ODMG, COM/OLE2) discussed.

     Herve Lejeune  has more  than 10  years  of experience  
     in computing  industry,  mainly  in O-O languages  and 
     systems. He was  one of the  main  contributor  of the 
     Object Transaction  Service which was  adopted  by the
     OMG and has participated to the evaluation  of several 
     CORBA implementations. He is  currently heading a team 
     in  charge  of   the  development   of  OMG  compliant
     components at Bull.

O-O Software Engineering
  Ivar Jacobson

     Level: intermediate (TA4)

     This  tutorial  defines  a  process  concept  for   O-O
     software  development which covers the whole life cycle
     for  software  products  (including   embedded   system
     software).  The  objective is furthermore to understand
     the need for several models in system building, how use
     cases  help  the  development  process  to  design  the
     requested system, to find the right objects, to work as
     the glue between different models and to structure each
     model of  a large  system, and  how  in the real world, 
     naive  objects  found  during  the analysis  activities 
     should   be   implemented   by   other  objects  robust 
     against future changes of  the  system.  The  following  
     topics  are covered:  the  process  concept,  different 
     scenarios  for the  process,  the  model  concept   and 
     the the use case concept. 

     Ivar Jacobson  is  founder  and VP  of  Technology   at
     Objective Systems in Sweden, a  software  company  that
     develops and markets  the  object-oriented  development
     method   ObjectOry. He   has  more  than  20  years  of
     experience   in  the  telecommunications  industry.  He
     developed an  early  object-based   design  technique a 
     major   portion   of  which   has   evolved   into   the 
     international standard CCITT/SDL.

Concurrent O-O Programming
  Peter Loehr

     Level: intermediate (TA5)

     Concurrency blends well with object orientation because
     an  object  is  akin  to a process. But there are still
     many choices for  how  to  exactly  relate  classes  to
     processes,   in    particular    with     accommodating 
     inheritance. We will explore different   approaches  to
     combining object orientation with concurrency and study
     programming languages  implementing  those  approaches.
     Distributed  implementations  are available for several
     languages; there are also languages especially designed
     for  massively  parallel  processing.  An assessment of
     how the user of those languages is affected by physical
     distribution  will  be  given,  and some implementation
     problems will be discussed.

     Klaus-Peter Loehr is a professor of computer science at
     Freie   Universitaet  Berlin, specializing  in   object
     technology  and  distributed  systems. He is  currently 
     leading  project  HERON  which  deals  with development
     support  systems  for  distributed  O-O   applications.

  William Premerlani

     Level: advanced (FM1)

     Besides mirroring the real world, an object  model  can
     also  be used to represent deeper abstractions, such as
     other models. For example, it is possible to model  the
     constructs  found  in an object model, a dynamic model,
     or  a  functional  model  with  object,  dynamic,   and  
     functional  models.  Such  models  of models are called 
     metamodels.  Although  they  are  often  difficult   to
     understand   and   construct,  metamodels  can  greatly
     increase  the  versatility of  software and  raise  the
     productivity  of  software  developers. Furthermore, if
     properly constructed, it is possible  for  a  metamodel  
     to describe itself. This tutorial covers several topics 
     related   to   metamodeling:  motivation   for    using 
     metamodels,   metamodeling    concepts,   examples   of 
     metamodels, and applications of metamodeling.

     William  Premerlani  is a  computer  scientist  at  the 
     General Electric R & D Center in Schenectady (New-York).
     His  research  interests  include  O-O   methodologies,
     applications of metamodels, and database technology. He

     (Prentice Hall, 1991).

Consistency checking and safe implementations for O-O models
  Guido Dedene & Monique Snoeck

     Level: advanced (FM2)

     This tutorial introduces  formal  consistency  checking
     techniques  for  O-O models to demonstrate how this can
     induce higher quality software specifications.   Formal
     techniques  are  based  on the expression of life-cycle
     constraints for object classes by means of  an  algebra
     of   idempotent   semi-rings.   The   uniqueness  of  a
     structure-preserving   partial   ordering   on    these
     semirings allows  to  classify object classes according 
     to existence  dependency. This  classification  is  the 
     basis   for  the   elimination  of  conflicting   class  
     behavior  specifications. The  classification indicates 
     when  relationships   are  needed  as  contract  object 
     classes. These techniques have been  developed  in  the  
     scope of the M.E.R.O.D.E  project  and  are  applicable  
     to  any O-O methodology that is making use of    event-     
     based  preconditions.   Examples   of  consistent   and 
     inconsistent models will be given.  The  transformation 
     of O-O  models into implementation models is discussed.

     Institute  for  Research  on  Information  Systems  and
     president   of  ELiAS, a  company    that  applies  O-O  
     techniques to library systems.

Formal O-O Methods
  Eduardo Casais & Thomas Lindner

     Level: advanced (FM3)

     Basing software construction on formal methods is a key
     issue  when  dealing  with the  production  of reliable
     programs. Formal O-O methods combine   the   advantages 
     of object-orientation, notably its  powerful   modeling 
     capabilities,  and  those  of  formal  methods such  as 
     verifiability  of   program  properties.  This tutorial 
     reports  on   the state  of  the  art  in  formal   O-O 
     methods. The issues to address when integrating object-
     orientation and formal   methods  are  considered,  and  
     various  integration   strategies  are presented. Major 
     formal approaches  (such as Object-Z, OSDL  or Z++) are 
     compared and  evaluated.   The  application  of  formal
     O-O methods is  illustrated with a  case  study dealing 
     with the specification  and implementation  of  control
     programs  for  the  model  of  a  manufacturing  plant. 
     The  advantages, but  also  the  traps  and pitfalls of 
     formal  approaches are  highlighted,  and their  impact  
     on  the  development  process  of  reactive systems  is
     discussed.  The  tutorial concludes on  how formal  O-O 
     methods  influence  the  software  development  process
     especially with respect to the problems  of reusability 
     of specifications and of modular verification.

     Eduardo Casais  worked  at  the  University  of  Geneva
     (Switzerland)  on methods for managing the evolution of
     O-O libraries. He is currently  head  of  the  Software
     Engineering  Department at the FZI and investigates the
     utilization of  O-O  methods  and  reusable  frameworks 
     in industrial applications.

     Thomas Lindner is currently a  researcher  at  FZI  and
     works on formal methods. He is active in different pro-
     jects dealing with the transfer of formal methods  into
     industrial  environments  and  has coordinated a large-
     scale case study in this field.

New Trends in the O-O Life cycle: the OSMOSIS View
  Jean Bezivin

     Level: advanced (FM4)

     This tutorial  presents  a  general  view  of  the  O-O
     software  life  cycle. The design process can be viewed
     as a composition of "corporate objects" (modeling enti-
     ties  from  the problem domain) and "technical objects"
     (modeling entities  from  the  computer  configuration,
     i.e. the means domain). This process is performed under
     the control of requirement scripts, a generalization of
     use  cases, and follows generic composition patterns or
     frameworks.  The general organization of the life cycle
     is defined and the following type of models identified:
     strategic,   requirement,   domain   analysis,  design, 
     technical,   test,   metrics,  formal    specification, 
     implementation, etc. Although these object-based models
     seems   to   emphasize    seamlessness        important 
     incompatibilities exist between them. To  capture their  
     similarities, differences and various relationships the 
     core  formalism of sNets  is  introduced.   Translation 
     examples  of  conventional   object   formalisms   into   
     sNets   are  presented,  showing  how it  builds up the 
     kernel  of  a nexperimental  environment,  the  OSMOSIS
     meta CASE. The tutorial starts with a brief description 
     of O-O methods (OMT, OBJECTORY, FUSION, SYNTROPY, etc.) 
     and  concludes on  how a  metamodeling  approach can be 
     used  to  provide  an  initial ontology of O-O software

     Jean Bezivin is professor of  Computer  Science at the
     University  of  Nantes (France) where he is  leading  a 
     Master Program entirely devoted to O-O technology.

Building models of Multimedia Systems
  Peter Ward

     Level: advanced (FM5)

     The tutorial is based  on  a  practical  and  pragmatic
     experience   and  a  multidisciplinary,  multiviewpoint
     approach to information systems development. It will be
     illustrated  with  a number of case studies and working
     applications. The use of OOT  and OOPL will  be  linked  
     with the development of models of multimedia. Notion of
     `information modeling'  and   the   design  of generic,
     flexible, enhanceable  and  distributable  O-O systems, 
     developed by  working  closely  with  users and in real 
     world applications are  discussed.  Key issues  include 
     portability, scalability and distribution; high quality, 
     configurable and  flexible user-friendly interfaces and 
     the providing of a variety of access and the support of
     key tasks in information modeling and communication.
