Categorization and Optimization of Synchronization Dependencies in Business Processes

requirement. Furthermore, programming using sequence constructs normally produce nested structures and The current approachfor modeling synchronization in scattered code, especially under the existence of business processes relies on sequencing constructs, such concurrency [21]. As a result, there is no easy way to add as sequence, parallel etc. However, sequencing constructs or delete a constraint in a process without over-specifying obfuscate the true source of dependencies in a business necessary constraints or invalidating existing ones. process. Moreover, because of the nested structure and In this paper, we describe a synchronization modeling scattered code that results from using sequencing approach for business processes in which dependencies sconsteruct it is hard to add or delete additional are first-class citizens, explicitly modeled to guide activityconstructs, ithardove r netesaryiconal scheduling.
