The Data Warehouse data transformation diagram is used to describe a Data Warehouse. The focus is on the description of the dynamic aspects described in the process view of the ARIS architecture.

The model illustrates the transformation of general information object data into InfoCube data formats. To ensure that you can proceed efficiently and without loss of data in the transformation, a method specification is required for modeling. The methodology contains transformation rules and procedures that are graphically represented in the model.

The transformation is realized in two steps. First, the transfer structure items are transformed into communication structure items. Then they are transferred to the InfoCube.

You can run this procedure on different levels. On the one hand, you can show at a very high (requirements definition) abstraction level which transfer and communication structures exist to fill the info cube. On the other hand, on a very low (implementation) level you can illustrate how individual data elements are mapped to each other.
