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

How to monitor and optimize OLAP databases and monitor olap Databases It is very important to optimize the performance of online analysis and processing. Fortunately, some tools can help monitor and improve the operation of OLAP databases. The Microsoft SQL Server Analysis Service (SSAS) provides a powerful engine used to create and manage data mining applicatio

business department knows the true meaning of the report representative, but does not know the report data statistical model. The IT department understands the description of the business department, it is difficult to understand the value of the report itself to set up a data statistics model on the Database End. As a result, the report tool cannot take both of them into consideration. the OLAP report to

In the report market, there is a strange phenomenon: the technical staff of the IT department is the department staff most unfamiliar with the use of report tools in all departments of the enterprise, but the report data comes from the IT department. The IT department often uses the OLAP concept to build a data model and create rep

IBM DB2 Data Warehouse Edition is a set of products that combine the strengths of DB2 Data servers and the robust business intelligence infrastructure from IBM. DB2 DWE integrates Core Components for warehouse management, data conversion, data mining, and OLAP analysis and reporting. In this article, we focus on the OLAP Service provided by DB2 DWE. What is OLAP?

a normalization of the star mode.. In snowflake mode, dimension tables in star mode are further layered. The original dimension tables may be extended to small fact tables to form partial "hierarchical" areas.It minimizes data storage and combines smaller dimension tables to improve query performance. The snowflake mode increases the number of tables that users must process and the complexity of some queries. But this can make the system more professional and practical, while reducing the gene

But sometimes for OLAP systems, we have pagination, and we can consider using each one SQL hint .

wrong execution plan is avoided. However, OLAP can use a lot of bitmap index, materialized view, for large transactions, as far as possible to seek speed optimization, there is no need to like OLTP need to submit quickly, or even deliberately slow down the speed of execution.3. SummaryEspecially in highly available OLTP environments, do not blindly use OLAP technology, such as partitioning technology, if t

OLAP (Online analytical Processing) is an online data access and analysis for a specific problem. Provides fast, stable, and interactive access to information (multidimensional data) in a variety of possible forms, and allows management decision makers to drill down into the data. first, what is OLAPOLAP (Online analytical Processing) is a kind of software technology that enables analysts, managers, or executives to gain a deeper understanding of data

One of the previous articles-the Data warehouse multidimensional data model already provides a brief description of the definition and structure of an overly-dimensional model, as well as the concept of the fact table and the dimension table (Dimension table). Multidimensional data model, as a new logical model, gives the new organization and storage form of data, and the advantage of the analysis is the effective operation and processing based on the model, which is
