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

Outstanding Features Allows for rapid, direct analysis of comprehensive financial, mathematical and statistical functions and computational functions Combine the flexibility of relational databases with the high performance of multidimensional storage to provide a web-enabled platform, easy access to enterprise-wide information enabling rapid application development and data modeling enables multiple users to simultaneously read and write to "what if" applications to support third-party analys

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

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, the statistical information and detail information of summary are provided. The report deve

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

Pivot and Unpivot Use a simple SQL spreadsheet-type crosstab report to display information from any relational table and store all the data in a crosstab table in a relational table. PivotAs you know, relational tables are tabular, that is, they appear in the form of column-value pairs. Suppose a table name is CUSTOMERS.Sql> desc Customers Name Null?

The difference between OLAP and OLTP and what is Data Warehouse OLAP is often referred to as a data warehouse. But the data warehouse is only part of OLAP, not all. OLTP multi-index than OLAP, and the real-time requirements of high, updated and modified many. OLAP generally

Many written interviews like to examine the fast line, so that you write a handwriting is not what. I learned this very early, and the process of fast sequencing is very clear. But the recent attempt to hand-write, found that the details of the algorithm is not accurate enough, many places even just an image in the brain, and did not understand its true nature intentions. So today combined with the "data structure" (Min), and "introduction to the algorithm" to Explore.First give a quick sort of

(Reproduced from Peking University Gaoke website, http://www.pku-ht.com /) The concept of Online Analytical Processing (OLAP) was first proposed by E. F. codd, the father of relational databases, in 1993. He also proposed 12 principles for OLAP. The proposal of OLAP has caused a great deal of response. as a type of product,

I'm not going to introduce the concepts of OLTP and OLAP here, and these are the same DBAs that are required to understand. Today's topic is why binding variables fit in OLTP systems rather than OLAP systems. In some ways, we can look at OLTP and OLAP systems like this, OLTP system small query many and OLAP systems are

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
