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.

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)

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 2009 04.29.2009
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 2009 04.29.2009
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 2009 04.29.2009
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.
