OLAP server can easily or smoothly answer to the complicated multidimensional queries. OLAP always comes in high speed. In fact it can be said that OLAP server is a true example of high speed processing. Nowadays, almost all types of business are thoroughly based on this online analytical processing as this processor can surely access a huge amount of data which simplifies a complicated business. OLAP server can spread through light on almost every wing of a business process that is business management, business reporting, business process management, marketing, budgeting, forecasting, financial reporting and many others.

With the help of this server very fast and flexible calculation as well as transformation of raw data can be done.

Output of OLAP server is usually displayed in matrix as well as pivot format. OLAP can give answers easily to multidimensional queries. Rows and columns which are usually displayed in OLAP server are formed mainly with the use of dimensions and these dimensions are generally derived from dimension tables. On the other hand the values of matrix are fully formed by measures.

Work of OLAP server depends on the OLAP cubes or multidimensional
cubes or you van say hyper cubes. In this OLAP system measures are some numeric facts. These types of numeric facts are normally derived from snowflake of tables or you can say star schema of tables. The Measures of OLAP can be divided by parts or categorized with the use of dimension. Work of OLAP is easier or you can say swifter than the work of OLTP that is Online transaction processing. OLAP server has become so popular that many large organizations in the world are using it and also getting huge benefits from its usage. This processing offers best solutions for data analysis for almost all types of business.

OLAP server uses mainly three types of data accessibility the first one is ROLAP, the second one is MOLAP and the third is HOLAP. ROLAP stands for Relational OLAP and MOLAP stands for Multidimensional OLAP and HOLAP stands for Hypercube. MOLAP uses the data from the relational database for making its own multi dimensional database which is helpful in producing the results in a very faster or quicker way. ROLAP directly takes the data from the relational database in processing its report which is just slightly slower than MOLAP in response time.
