Understanding Oracle OLAP Enhancements
 

From the bestselling Oracle10g book, Oracle Database 10g New Features.

by Mike Ault

Oracle 10g introduces new OLAP capabilities, using the built-in analytical workspaces of the Oracle database. There are many new PL/SQL and XML-based interfaces that aid in the creation of workspaces, based on the cubes, dimensions, measures, and calculations defined in the OLAP database catalog. These new interfaces can be used by the new packages provided or by Oracle Enterprise Manager to define and build analytical workspaces. This removes the need for the user to learn OLAP DML commands. Now you are in the familiar territory of PL/SQL Packages and OEM!

Oracle 10g also provides significant help with performance enhancements. New parallel capabilities are provided for aggregate and sql import operations, making it much faster to load and materialize analytical workspaces from relational database information. And 10g also provides many hierarchy-related improvements.

We will examine some of these improvements next.
