OlapCube

OlapCube is a simple, yet powerful tool to analyze data. OlapCube will let you create local cubes (files with .cub extension) from data stored in any relational database (including MySQL, PostgreSQL, Microsoft Access, SQL aServer, SQL Server Express, Oracle, Oracle Express).The OLAP cube consists of numeric facts called measures which are categorized by dimensions. An OLAP cube is a data structure that allows fast analysis of data. The arrangement of data into cubes overcomes a limitation of relational databases. Relational databases are not well suited for near instantaneous analysis and display of large amounts of data. Instead, they are better suited for creating records from a series of transactions. Although many report-writing tools exist for relational databases, these are slow when the whole database must be summarized.
