Functional Database Model

The functional database model is used to support analytics applications such as Financial Planning and Performance Management. The functional database model, or the functional model for short, is different from but complementary to, the relational model. The functional model is also distinct from other similarly named concepts, including the DAPLEX functional database model, and functional language databases.The functional model is part of the online analytical processing (OLAP) category since it comprises multidimensional hierarchical consolidation. But it goes beyond OLAP by requiring a spreadsheet-like cell orientation, where cells can be input or calculated as functions of other cells. Also as in spreadsheets, it supports interactive calculations where the values of all dependent cells are automatically up to date whenever the value of a cell is changed.
