What Development Issues Did EDD Solve?
The EDD’s first attempts at a prototype used client-side tracking of user data, but it was sorely limited. In late 1995, the EDD became aware of WebHub, which at that time was unique in providing server-side saving state as a built-in feature. Saving state is the ability to retain the user’s identity throughout the session within a dynamic site. This prevents the user from having to provide the same information multiple times. The pilot, written with WebHub, maintains the user’s result sets on the server side throughout the session thereby allowing complex drill down queries.
