Inside the Oracle BI Server Part 1: The BI Server.
About Oracle BI Server Architecture The Oracle BI Server is an Oracle Business Intelligence component that processes user requests and queries in underlying data sources. The Oracle BI Server maintains the logical data model and provides client access to the model using ODBC connectivity or native APIs, such as OCI for the Oracle Database.
It maintains a Presentation Catalog service on the file system for the customization of this presentation framework. It is a standalone process and integrates with the Oracle Business Intelligence Presentation Services Plug-in from which it receives web client requests. It communicates with the Oracle Business Intelligence Server using ODBC.
OBIEE Architecture involves various BI system components which are required to process the end user’s request. How OBIEE System Actually Works? The initial request from the end user is sent to the Presentation server. The Presentation server converts this request in logical SQL and forwards it to BI server component.
Taking the standard OBIEE architecture diagram, the BI Server sits in the middle of the OBIEE set of servers and provides the query capability, security, interfaces to data sources and calculation logic for OBIEE (all of this is based on the current, 10g set of products).

The Oracle Business Intelligence system logical architecture comprises a single integrated set of manageable components called the Oracle BI domain which can be installed and configured to work together on a single host or can be clustered across multiple hosts for performance and availability.
Oracle BI Presentation Services is an extension to an existing Web server. It receives processing instructions from an Oracle BI client, retrieves the requested information from Oracle BI server, and then renders the information inside the requesting client.
The Oracle Business Intelligence Presentation Services provides the framework and interface for presentation of Business Intelligence data to web clients. It maintains a Presentation Catalog service on the file system for the customization of this presentation framework.
The Oracle application layer or popularly known as the Fusion Middleware layer is built upon a common domain-based architecture that can support as a set of common core functionality (like security, scalability etc) across various Oracle products. This is implemented with the Weblogic domain as shown in the diagram (Oracle BI domain).
Oracle Business Intelligence Applications are built on the Oracle Business Intelligence Suite, Enterprise Edition Plus platform—a next-generation analytics platform and data model that fully leverages existing data warehouse and BI investments. Using a metadata-centric architecture.

Oracle Business Intelligence Server The foundation of the Oracle Business Intelligence Suite Enterprise Edition Plus platform is a true BI server that is designed to be highly scalable, optimizing concurrency and parallelism to make the value of BI applications available to the largest possible audience.
MMAN is the memory manager that automatically manages memory in an Oracle database. LREG is the listener registration process that registers information on the database instance and dispatcher processes with the Oracle Net Listener. Now, you should have a good overview of the Oracle Database architecture and its components.
Oracle BI 11g Architecture Components Descriptions. Oracle BI Presentation Services — This component provides the framework and interface for the presentation of business intelligence data to Web clients. It maintains an Oracle BI Presentation Catalog service on the file system for the customization of this presentation framework.
