26. Increase User Productivity with Composite Applications
ADD A COURSE
Adding a Course gives you a view that shows your current classes and an area where you can browse courses and view in real time if there is an opening in the course and more detailed information before applying for it. Class status of being open or closed will update in realtime.

27. Increase User Productivity with Composite Applications
ADMIN REPORTS
This is an example of how powerful in Context applications are in this report. An Administrator will be able filter the Data, drill in even more and act on it to make a more informed decision.

28. Customer Best Practices
Extend and Reuse Legacy Applications and Business Functions as Fine Grained or Business Services
Implement an Enterprise Service Bus (ESB) as the ‘back bone’ of your SOA, to allow services to be loosely coupled and allow for the creation of composite services
Implement a SOA Governance and Management Tool, to allow for management, impact analysis and life-cycle management in the new Architecture
Implement a robust security layer to protect web services, even if they are only deployed internally
Implement Best Practices and Methodologies to ensure reuse of services and to support Business and IT resources
