  3. Traditional approach: ad hoc, non repeatable Fixed business processing guidelines and rules One person in charge of one treatment Challenge for improvement: Interactive, pre-planned, Web-based, pattern-controlled Flexible, individually configurable/ designable Groupwork-oriented Design methodology and design tool required Workflow aspects for document processingin Electronic Commerce Applications„Programming“ the document modification chain Forget it!

  4. Typical examples: Document state modification (specialized from State [GHJV 95]) Database query (using, e.g., Facade/Proxy/Client-Dispatcher-Server [GHJV 95]/[BMRSS 96]) Dependency/Observer/Broadcast Time association [COAD 92] and many more Workflow composition, some ideas & examples: Essay based web site[PLoP 96] Conditional chain of activities Pattern-based integration architectures [PLoP 95] Plan patterns [COAD 97] Lifecycle and refactoring patterns [PLoP 95] Chain of responsibility[GHJV 95] Master-Slave [BMRSS 96] Application ofPattern Technology [GHJV 95] Gamma et al., Design patterns [BMRSS 96] Buschmann et al., Pattern-oriented software architecture [PLoP] Pattern languages of program design

  5. SummaryDocument workflow under pattern control,a project proposal • Participation sought in an EU 5th framework R&D project • OO modelling and specification of workflow patterns • Starting from available document composition framework HotDoc[BUCHNER 98] -- regrettable not yet „patternized“ -- • Architecture and specification of a „visually-supported workflow design tool“ for workflow composition based on appropriate patterns • No implementation (prototypical implementation in the scope of the MALL2000 project) • Time frame 1999 - 2000
