MDBMSs are created using input from existing relational databases. They have the ability to process data in a database by allowing answers to be generated quickly. Data is presented to users so as to represent a hypercube or multidimensional array, where every individual data value is contained within cells that are accessible by multiple indexes. The multidimensional systems are capable of moving beyond three dimensions.

MDBMSs are well known for their ability to present data in top level views. The main advantages of using a multidimensional database system are:

• Increased performance
• Easy maintenance
• Enhanced navigation and data presentation
