Online Analytical Processing Tools : OLAP, Online Analytical Processing tools enable to analyze multidimensional data interactively from multiple perspectives. OLAP involves relational database, report writing and data mining and consists of three basic analytical operations consolidation such as roll up, drill down, slicing and dicing. Consolidation is the aggregation of data that can be accumulated and computed in one or more dimensions. Drill down allows users to navigate through the details. Slicing and dicing let the users do slicing and dicing, by taking out a specific set of data of the OLAP cube and view the slices from different viewpoints. OLAP databases uses a multidimensional data model, allowing for complex analytical and ad hoc queries with a rapid execution time and also includes features of navigational databases, hierarchical databases and relational databases. OLAP system consists of an OLAP cube , which is also known as multidimensional cube or a hypercube . OLAP cube consists of numeric facts called measures which are categorized by dimensions. The measures are placed at the intersections of the hypercube, which is spanned by the dimensions as a vector space. The cube metadata is typically created from a star schema of tables in a relational database. Measures are derived from the records in the fact table and dimensions are derived from the dimension tables.

Online Analytical Processing Tools

Online Analytical Processing tools are classified as MOLAP – multi-dimensional online analytical processing, ROLAP- relational online analytical processing, HOLAP-hybrid online analytical processing, WOLAP-web based online analytical processing, DOLAP- desktop online analytical processing and ROLAP- real time online analytical processing

MOLAP – Multi-Dimensional Online Analytical Processing

MOLAP is the classic form of OLAP and is sometimes referred to as just OLAP. MOLAP stores the data in an optimized multi dimensional array storage and requires the pre-computation and storage of information in the cube.

IBM Cognos, SAP NetWeaver BW, Microsoft Analysis Services, MicroStrategy Intelligence Server, Mondrian OLAP server, Essbase, icCube, Infor BI OLAP Server, Jedox OLAP Server, Oracle Database OLAP Option, SAS OLAP Server, IBM TM1 are some of the top MOLAP Servers.

ROLAP- Relational Online Analytical Processing

ROLAP stores the data in relational databases and depends on a specialized schema design. The base data and the dimension tables are stored as relational tables and new tables are created to hold the aggregated information.

IBM Cognos, SAP NetWeaver BW, Microsoft Analysis Services, MicroStrategy Intelligence Server, Mondrian OLAP server, Essbase, Jedox OLAP Server, Oracle Database OLAP Option, SAS OLAP Server are some of the top ROLAP Servers.

HOLAP- Hybrid Online Analytical Processing

HOLAP addresses the shortcomings of MOLAP and ROLAP by combining the capabilities of both approaches where a database will divide data between relational and specialized storage.

IBM Cognos, Microsoft Analysis Services, MicroStrategy Intelligence Server, Mondrian OLAP server, Essbase, Jedox OLAP Server, Oracle Database OLAP Option, SAS OLAP Server are some of the top HOLAP Servers.
