OLAP options in Oracle9 I Database Release 2 introduce the analysis workspace and truly integrate the relational and multidimensional data types in the same Database. So far, the only way for developers and DBAs to use the analytic workspace is to use command line API calls to manually build them. However, with the latest Analytic Workspace Manager (AWM) version, you can better utilize the multidimensional features in

The multidimensional arrays of these dimensions and the measured indices are the basis of OLAP analysis, which can be formalized as (Dimension 1, Dimension 2, ..., dimension n, metric), such as (region, time, product, sales). Multidimensional Analysis refers to the multidimensional form of the data organized by slicing (Slice), Cut (Dice), drilling (Drill-down an

Oracle OLAP FunctionsThis topic has been used a lot recently. I have summarized it.

I have some experiences in using Oracle OLAP recently. Take a note:
Oracle data warehouse has many implementation methods. I know two methods:
One is ROLAP, which is based on fact table and dimension table. These tables are based on relational Tables, that is, general partition tables. Based on these partition tables, materialized view and partition are added, t
Oracle was originally designed to be transaction-based, so it won't be authentic in terms of processing analyticdb. Recent developments in Oracle-related technologies have gradually adapted to OLAP needs.

In the use of Oracle databases, Backup recovery is the most critical. When the database fails, it can be restored in a timely manner to reduce unnecessary losses. Next I will briefly introduce the import and export of databases, solutions, tables, and the role of things in the Process of use.1.

Oracle 11g on July 11, 2007 11 O'Clock (Beijing time 11th 22 o'clock) officially released, 11g is Oracle 30 years to release the most important version of the database, according to the needs of users to achieve information lifecycle management (information Lifecycle Management) and many other innovations.

Now there is a need to use Exp/imp to import 11g of database data into 9i, to solve this problem generally think of three ways of thinking, try (in fact, from the high version of the server to support the low version of the client principle, you can probably guess the use of 9i client to handle the problem)
