Hi,
Express is a multi-dimensional database and application development environment for building OLAP applications.
At the heart of the Express server are dimensions and variables. Dimensions are the elements that an Express database is broken down by. These are often the "keys" of a database. Examples of dimensions are PRODUCT, REGION or TIME.
Variables are the objects that hold data in an Express database. These are simply arrays of values (usually numeric) that are "dimensioned" by the dimensions in a database. For example, a SALES variable may be dimensioned by PRODUCT, REGION, and TIME. This three-dimensional variable or array is often visualized as a cube of data.
Express databases can have multiple variables, with common or a unique set of dimensions. This multi-dimensional view of data is especially useful for OLAP applications.
Best regards
Frank Naude
