Abstract:
The paper presents motivations, the idea and design of an object-oriented declarative workflow management system. The main features that differ this system from many similar systems are: inherent parallelism of all workflow instances and tasks, the possibility of dynamic changes of running process instances and integration of workflow instances with an object-oriented database. Workflow instances, tasks, subtasks, etc., are implemented as so-called active objects, which are persistent data structures that can be queried and managed according to the syntax and semantics of a query language. and also possess active parts that are executable. The prototype has been implemented on the basis of ODRA, an object-oriented distributed database management system. As the workflow programming language we use SBQL, an object-oriented database query and programming language developed for ODRA.
