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 Oracle
we perform a 32-64-bit dB migration, we will need to recreate the OLAP component. Otherwise, a large number of invalid objects will exist. This reconstruction takes nearly 40 minutes, so it is a very time-consuming process.

Today's data processing can be roughly divided into two categories: online transaction processing OLTP (on-line transaction processing), Online Analytical Processing OLAP (on-line analyticalProcessing ).OLTP is the main application of traditional relational databa
The concept of online analytical processing (OLAP) was first proposed by the father of the relational database, E.f.codd, in 1993, and he also presented 12 guidelines on OLAP. OLAP has aroused a great deal of response, OLAP as a class of products and online transaction processing (OLTP) clearly distinguished.
Today's
The history and basic concepts of OLAPOLAP is all called online analytical applications, and is a solution for multidimensional data analysis queries. Typical OLAP applications include sales, marketing, management and other business statements, budget accounts, economic statements, and so on.The earliest OLAP query tool was the Express published in 1970, but the complete
Abstract: Based on the Data Storage Technology of ODS in the middle layer of DB and DW, a real-time OLAP system for commercial systems is designed from the perspective of application. ODS is used to overcome the problem that DW is too bloated for decision-making and is not suitable for enterprises' real-time middle-level decision-making.

Introduction to OLTP and OLAP
Data processing can be broadly divided into two broad categories: online transaction processing OLTP (on-line transaction processing), online analytical processing OLAP (On-line Analytical Processing). OLTP is the main application of the traditional relational database, mainly basic, daily transaction processing, such as bank transaction. O
