Hi chander72,

Here is a brief history of each version of WebSphere. Good Information.

Hope this help,

Version 4

This was a J2EE 1.2 certified application server. It inherited the database-based configuration model from V3.x for all but the single-server edition, which already used an XML datastore.
AE (Advanced Edition)
AEs (Advanced Edition single). Single-server edition that was not able to run in a cluster configuration.
AEd (Developer Edition). Functionally equivalent to AEs, but intended only for non-production development use.
EE (Enterprise Edition)

Version 5

The version released on 19 November 2002. This was a J2EE 1.3 certified application server. It was a major rewrite of the V3/V4 codebase and was the first time WebSphere Application Server was coded from a common codebase. Now WAS across all deployment platforms, from Intel x86 to the mainframe, are substantially the same code. The database-based configuration repository was replaced with a replication XML file-based configuration repository. A service called the Deployment Manager had the master copy of the cell configuration, and nodes had the file(s) they needed copied from this master server whenever they changed. V5 also included a miniature version of MQ 5.3 called the embedded Java Message Service (JMS) server.
Express Edition replaces the Standard Edition. Express now becomes the term to indicate SME-oriented offerings from IBM, across all its software brands.
Base
Network Deployment. This version supports deployment of a cell configuration with cluster and J2EE failover support. It now also includes Edge Components, previously known as Edge Server. This provides a proxy server, load balancing, and content-based routing.
Enterprise Edition. This version added a workflow engine, called the Process Choreographer, for the first time but predates the BPEL standard. It also added the first fully supported application threading model called WebSphere Asynchronous Beans.
WebSphere Application Server for z/OS. This version is essentially the same as the Network Deployment product but is optimized to take full advantage of z/OS features, such as Workload Manager, to leverage the key technologies that make the mainframe indispensable for mission-critical, scalable, and secure workloads.
