The Advanced Single Server Edition (AEs) of WebSphere provides the same core J2EE and WebServices programming model as the Advanced Edition (AE) with simplified administration. In the AEversion WebSphere uses DB2 or other standard database to keep the configuration and runtimeinformation to support very large farm of WebSphere servers. However, it is one more database toinstall, administer and maintain. The AEs version does not use the database and uses file basedconfiguration in a way that is similar to BEA WebLogic. PeopleSoft and IBM WebSpherearchitects determined that AEs version would satisfy the deployment requirements of PeopleSoftcustomers and would make it easy for owning and administering PeopleSoft Applications basedon WebSphere.
