Now comes the crucial part, the modeling of the ETL coordinate and basis transformations. This modeling is done separately for each dimension (including degenerated dimensions). Using dimension Date as an example, we must create a transformation T that takes the Timestamp attribute A3 as input and calculates the attributes B1 = Day, B2 = Month, and B3 = Year. ,A6 . ,B3 . Analogously, ETLToDimensionFactorys must be created for each dimension. If the TransactionMart’s etl-method is invoked, the following etl-method invocations are triggered (repeated invocations of the same etl-method are prevented by a cache): ETL method of Transaction Transaction Type Date Session Session ID Date Customer Customer ID Location Date Customer ..

Am , m ∈ N and let p : μ(A1 , . . , Am ) → P be a one-to-one and onto mapping. ,Am maps any vector a ∈ D(A1 , . . , Am ) to a one-dimensional user-defined domain P. p is called primary key mapping, since it assigns a unique primary key to any given vector in D(A1 , . . , Am ). e. ,Am (ai ), i = 1, . . , n. ,Am , p as dimension. If m = 1, D is called degenerated dimension. A dimension is based on a data matrix (for example a database table), the primary keys of which are calculated by the primary key mapping for every vector, which is inserted into the data matrix.
