A multidimensional database-or a multidimensional database management system (MDDBMS) - implies the ability to rapidly process the data in the database so that answers can be generated quickly. A number of vendors provide products that use multidimensional databases.Approaches to how data is stored and the user interface vary. Conceptually, a multidimensional database uses the idea of a data cube to represent the dimensions of data available to a user.For example, sales could be viewed in the dimensions of product model, geography, time, or some additional dimension.pproaches to how data is stored and the user interface vary.

Gadfly is a relational database management system which uses a large subset of very standard SQL as its query language and Python modules and optional Python/C extension modules as its underlying engine.Gadfly stores the active database in memory, with recovery logging to a file system.urthermore the Gadfly database storage format (based in the Python marshal format) is binary compatible between all these systems -- you can create a database on any one of the systems and use a binary transfer mechanism to any other system and the database should load and run.
