TTraq is a time tracking (timesheet) system that helps consultants, employees, freelancers, or service providers of any kind who work in a project oriented environment. It is a sophisticated Web application based upon the Struts framework by the Apache Group. It is easy to set up and very quickly accessible. The data is managed via the Hibernate persistence framework. It should run on any J2EE compliant container. All data can be exported to CSV, HTML, or Excel. A backing store (database) is included in the distribution.
con:cern is a workflow engine based on an extended case handling approach. A process is described as a set of activities with pre- and postconditions. An activity is executed when its preconditions are met. It manipulates the process item, thereby creating postconditions. The process flow is determined at runtime. This approach is superior to the conventional process flow approach, especially if high flexibility and modularity are required.
