Prof. PÂRV Bazil, Ph.D., bparv cs.ubbcluj.ro |
| Aims |
|
• To introduce the notions of ‘workflow’, and workflow system.
• To analyze several workflow case studies in order to emphasize the advantages of separation of workflow from business logic. • To emphasize the relation between workflow technology and business processes management • To present the workflow reference model BPR / BPEL • To presents the most important workflow patterns. • To present several concrete solutions for workflow modeling. |

| Assessment |
|
The final mark will cover lab work (i.e. completing a project) and research work (preparing a research paper), as well as the written exam results. It is computed as follows, on a 10-point scale, 1pt by default:
• 10% attendance • 20% the project • 20% the paper • 40% the written exam. |
