A Smalltalk-based system for dynamic multi-context information processing experience report

van Os, Adriaan and Westerhof, Eugene: LEI - Wageningen UR

Monday 4:45 pm to 5:30 pm

Abstract: In spite of the dynamic character of information need, software systems should preferably be stable. Software changes are expensive and are a risk to system stability. This is why we want to separate the software engineering process from the information systems development activities. For this purpose LEI developed a Smalltalk-based system for model-based system specification and workflow management. System behavior is dynamically generated from data specifications, constraints, computation models and workflow specifications. In our presentation we will explain the construction of the system and the main principles it is based on. We will demonstrate how context-independence of the data model has been achieved and how the workflow engine schedules the workload.
