In the current excitement world of internet the world wide web has a lot to offer .The OLAP servers very much concerned of the need to obtain quick access to huge amount of data and so this a technique which is useful for sorting out queries that are multidimensional and of analytical nature which comes into existence form different parties understands as to how the data is organized in the database and has tome special functions for the purpose of analyzing the data .In nearly all major database systems there are OLAP server. The OLAP server may be either physically stages the processed multi- dimensional facts to the end-users or it may populate its data structures in real-time from relational or other database. If present technology is considered and the requirement of the end user in staging the multidimensional data then this type of server is often the most preferred method.
An OLAP server primarily serves the purpose of quickly giving answers to multidimensional analytical questions by different parties. The system as such is very much a par of the business intelligence domain.
The use of the term OLAP primarily is created form online transaction processing which is very much a traditional data base term. The area where OLAP server is most used in business reporting is in regard to areas of sales, marketing, budgeting, and in management reporting. The configured databases for this system are primarily based on a multidimensional data which allows the rapid resolution of very much complicated queries by taking parts of navigational a hierarchical databases that are in comparisons faster than relational databases. OLAP server mainly employs the functionality of a multi dimensional cube. The data is generally derived form a star or snowflake schema of tables. There are claim that OLAP cubes can devise an answer rapidly and the device that permits for such rapid speed is the usage of aggregations. An important fact of OLAP servers is that it is being increasingly used by organizations around the globe to speed up processes and to simplify things for the workers who are related to IT.
