The management agents were written in C#. WSS 3.0 was used in the solution to provide reports to the client through web parts and SSRS. SSIS packages were utilized to generate delta views of the data coming from Oracle into the SQL Server tables. This was used primarily for performance reasons.

Designed and developed a POC that integrated MOSS 2007 and ILM 2007. This was achieved by building a custom management agent in ILM that integrated with the built-in web service API’s in SharePoint 2007.

Based on client requests I was able to get the portal to run in MOSS 2007. Also, clients requested more flexibility in the design in the portal solution which was not possible since the majority of the site was built using SharePoint server controls. To provide that flexibility I created a new portal in WSS 3.0 using web parts that integrated with FIM 2010’s WS-* web services to provide basic CRUD operations.
