The eprentise architecture is built on a multi-tiered, distributed computing model. The architecture comprises: 

• A client tier that supplies the user interface
• An application tier responsible for servicing requests and providing responses to the client tier
• A database tier, which hosts and manages the eprentise schema

Client tier

The client interface is provided as HTML pages which can be accessed via a URL on a standard web browser. Users log into the application through a Login link provided on the eprentise Index page. You can use a standard web browser (e.g., Internet Explorer 6.0+ or Mozilla Firefox 2.0+) on any type of networked work station.

Application tier

The application tier provides for client side validation and manages the communication between the client tier and the database tier. The Application tier also hosts the eprentise reports engine. The current version of the eprentise software is supported on any Linux or UNIX platform that is also capable of supporting Oracle database versions 9i and above. Apache Tomcat server provides the technology component services and acts as the web server, processing the client requests by way of Web Listener and Java Servlet Engine (JSP).

Database tier

The eprentise database schema houses the eprentise knowledge repository and the core rules engine. The eprentise schema is created with its own dedicated data, index, temporary table space, and all the database objects required to operate when you install the software.

Both application and database tiers may reside on the same physical server that hosts your Oracle E-Business Suite test or production instances. It must at least reside on a server that has a DBlink connection to these instances.
