OLAP is the main application of the data warehouse system. It supports complex

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?

can improve the speed of translation. If you only translate a page of books, but also to assign different people to translate different lines, and then combine, there is no need, because in the time allotted work, a person may have been translated.Bitmap indexing is also the same, if used in the OLTP environment, it is easy to cause blocking and deadlock. However, in the OLAP environment, the query speed may be increased because of its unique charact

analysis, which is the common analysis method: Ad-hoc query: Ad hoc queries are users according to their own needs, flexible choice of query conditions, the system can be based on the user's choice to generate the corresponding statistical reports. Fixed field analysis: That is, the user's query conditions are fixed, we can follow the defined fields to provide reports, such as weekly, monthly Keyword query: For example, the user's address is Beijing Chaoyang District xxxxx, the

In this paper we present BATCHDB, a in-memory database engine designed for hybrid OLTP and OLAP workloads. BATCHDB achieves good performance, provides a high level of data freshness, and minimizes load interaction between the TRA Nsactional and analytical engines, thus enabling real time analysis over fresh data under tight SLAs for both OLTP and OLA P workloads. This article describes a

Is OLAP a bi? Posted by admin on 12月 1st, 2007. Filed in 技术--> In order to determine the business activities carried out by the business strategy and market strategy, enterprises must analyze and make decisions based on multiple reports and reports in the analysis and decision-making process of Bi projects. Most of the ideal marketing activities require sales reports for each business point, and performance charts for each product to be sold by sea

improve the response speed. (2) Multidimensional service engine Most OLAP applications perform multidimensional computations on the multidimensional services engine and have good performance. Because this approach optimizes both the engine and the database, the full memory on the server guarantees the efficient computation of a large number of arrays. (3) Client Computing on the client computer require

In order to determine the business activities carried out by the business strategy and market strategy, enterprises must analyze and make decisions based on multiple reports and reports in the analysis and decision-making process of Bi projects. Most of the ideal marketing activities require sales reports for each business point, and performance charts for each product to be sold by season. A large amount of accurate and easy-to-Judge data is required. However, it is a huge workl

OLAP (Online analytical Processing) is an online data access and analysis for a specific problem.

What is OLAP and OLTP Source: http://www.itisedu.com/phrase/200604230827105.html Http://www.huihoo.com/database/dw2.html 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

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
