In three-tier computing, application logic is held in an application server, such as Sybase EAServer, which sits between the resource manager and the client applications. In many situations, a single application server may access multiple resource managers. In the Internet case, client applications are browser-based, and the application server is generally a web server extension.
Sybase EAServer stores application logic in the form of components, and makes these components available to client applications. The components may be PowerBuilder components, JavaBeans, or COM components.
For more information, see your Sybase EAServer documentation.
