The server to OLAP functions helps in facilitating the manipulation of high capacity data. It's a multi user engine specifically designed to enable the processing of multiple user queries. It helps in arranging the available information in a dynamic way and it also supports and operates the multidimensional databases in a structured manner. The methodologies used by OLAP Server apart from data mining & relational reporting are the parts of this business intelligence software.
The term known as OLAP is derived from online transaction processing (OLTP), the oldest term used for database manipulation. OLAP server is frequently used these days in many aspects of a business such as business reporting, budgeting, management and finance reporting. The database which is configured for using this methodology is based on the multi dimensional data model which allows quick resolutions to the complex data queries by the end users by retrieving some parts of the navigational & hierarchical databases which are much faster than the relational databases. The output of OLAP queries are normally available in matrix formats where the dimensions form the rows and the columns of the database and the values are formed by its values.
In terms of conceptualization, the OLAP Server employs the functionalities of multidimensional cubes, which are also called OLAP cubes. These cubes contain the numeric facts which are categorized using their dimensions. The data is derived from the star tables of a relational database. In a simple manner, all measures which can be seen have a set of labels associated where the dimensions describing these labels and providing the details of the measures. The developers of this system claim that the OLAP cubes can devise the answers of queries in around .1% of the time which is normally taken by the traditional OLTP relational databases. The mechanism which is used by OLAP for allowing such a speedy processing is the use of aggregations which are built from the fact tables after altering their granularity on the specific dimensions to aggregate the data. The fact is that the system OALP server is used massively by the business houses across the world for speeding up their business process and simplifying the things.
