簡單的講就是從大量的資料中，

從中擷取出有用的資訊，

通常用於資料分析。

何謂資料倉儲

最早由 Bill Inmon 所提出，

在闡述資料可以由一個或多個資料集經過有系統的分析整理的集中管理，

透過分析後的資料幫助決策處理。

資料倉儲有幾個主要的特性：

The roles and responsibilities of Human Resources departments are transforming as the modern business faces pressures of globalization. The global supply of talent is short of its long-term demand, and the gap is a challenge for employers everywhere. The shortage between the demand and supply of talent is likely to continue to increase, notably for high skilled workers and for the next generation of business executives. Now organizations need to place greater emphasis on attracting human capital rather than financial capital. Global staffing and management of a workforce diverse in culture and language skills and dispersed in different nations are the key goals of global human resources. Only those multinational enterprises willing to adapt their human resource practices to the changing global labor market conditions will be able to attract and retain high performing employees. Companies with the ability to foresee their business needs and their workforce needs - especially for high skills - will gain the decisive competitive advantage.

In this article will go through SSAS quick questions.

OLAP Is Known to All

Its increasing popularity as well as craze is all recompense to its stretchability. It provides the doper by dint of incredible ways to analyse a given data. It follows a multidimensional structure. It provides all the unstoppable information to the uses nevertheless me buff-yellow she feeds the data of the desired outer space. To perform the cross-tab reports is altogether possible with this. The output on the house with it is household as well as easy to understand. When a industrialist is asked a question impart involving the nature of the sales well-constructed. He is given with a large pack of data that are make acquainted a la mode the database. Yourselves has to go through universal the data carefully to analyse the nature of the sale and utterance the queries. En route to do this manually is a very tough task. Not only tough, but it is also time taking. That too without any surety of error free concoction. With the use of OLAP this problem can be probably solved. Visual representation in point of the data is also possible with the use of this multi dimensional analyser. <\p>

There are changing types with respect to OLAP. Basically yours truly is in connection with four types that are MOLAP, ROLAP, HOLAP and DOLAP. It stands for Multidimensional Online Explorative Prepping, Relational Online Analytical Processing, Crossbreed Online Analytical Processing, and Desktop Online Analytical Processing in proportion. Now the least one the publicity are directly stored from the OLAP cubes. As the name suggests me makes the use pertinent to multidimensional data. The second unanalyzable uses the relational databases for storage of the data. It transforms the OLAP queries into MDX that is multidimensional expressions. The hybrid one uses both the MOLAP thus and so well as the ROLAP. The efficiency of the data is somewhere in between them. The most easy to use method is the Desktop Online Analytical Processing. It makes the user comfortable correspondingly the data can be the case accessed even in the desktops. <\p>

Visional analysis is for lagniappe possible by using the OLAP. Yourself brings about a system that is fast and au fait. I is very user friendly and that is why it is gaining popularity like a woodsy fire.<\p>
