AFUNCTIONALITY COMPARISON FRAMEWORK FOR OPEN SOURCE WORKFLOW ENGIN

Abstract

The selection of a workflow management system may be very difficult and complex. This research proposed a comparison framework that help developer selects the most suitable workflow management system and offers comparison of two popular workflow management systems. Moreover this research describes the promotions process as workflow case study, analyzes this process and implements it on the two selected workflow system tool (joget and processMaker). The proposed Framework is an extension to Garcês et al. survey framework. The research adds three extra features to their framework. After the systems have been implemented, the research compared the two systems using the comparison framework. The result shows that both tools are fully compliant to the WFMC reference model specification. In Functional Areas, Both tools in Documentation, installation and utilization, web based, require java JDK, support middleware platform, DBMS integration, Process Definition and in support organizational perspective have the same score. In transaction support, joget support exception handling and rollback while processMaker only support rollback. Both tools support parallel task. Joget provide user view which allows us to design graphical user interface while processMaker doesn،t provide that. In Email server joget send email message to a predefined targeted recipient(s) through a set of primary and secondary SMTP servers while processMaker send email message to a predefined targeted recipient(s) and can send Email from a value that is enter by users in executions time. In variables joget only uses variables in decision while processMaker use it in decision, storing data and retrieve data from forms.
