Introduction What is Work Flow? A Workflow is an automation of business process within which information, tasks or jobs are passed from one entity to another. Some Examples  Credit Card application processing.  Product design and development. CSCI 6838 Spring

Existing Application TieFlow Workflow Toolkit TieFlow Workflow Toolkit is a web based electronic workflow system. Used to automate manual form based process. Major Function Create, display, modify process definition in XML. Workflow engine uses XML process definitions to load database tables to execute process. Current uses NASA's Flight Director's Office uses the same for its Flight Rules Change Request (FRCR) CSCI 6838 Spring

Dynamic Repeat Introduction What is Dynamic Repeat? Basic Idea –A new repeat expression for Timer. –Can be specified in a time period or an implied manner. Differences with Normal Repeat –Dynamic Repeat can be specified through database values, constant values and ContentData Values –Dynamic Repeat so can be specified in a implied manner consisting of Repeat Months, Weeks, Days, Date and Time. CSCI 6838 Spring

Approach of implementation to Dynamic Repeat It was a new and a unique element It consists of mainly three elements. –Dynamic Repeat Time Period –Dynamic Repeat Day –Dynamic Repeat Date We divided the implementation into three steps –Parse the new Dynamic Repeat Element –Assigning and Displaying the values for the element –Writing out the new values in XML Specification CSCI 6838 Spring

Implementation of Dynamic Repeat We have created all the necessary classes and also suitably changed other supporting classes. Dynamic Time period element is working almost completely. We are able to create new specification using the GUI for the new Dynamic Time Period and save the specification. For Dynamic Day and Dynamic Date we have created the related GUI and the functions to parse these elements. CSCI 6838 Spring

Problems Does not write out the Dynamic Date and Day elements correctly. The GUI is incomplete for Dynamic Day and Date and needs to have few more functions to support the dynamic elements. Dynamic Time period GUI should support the Content Data, Database and Constant Values. CSCI 6838 Spring
