Data Mart Interface Between Several Systems

Use

The data mart interface can be used between two BW Systems or between another SAP system and a a BW System:

to enable large amounts of data to be processed
to increase the respective speeds of data transfer, logging and analysis.
to achieve improved concision and maintenance of the individual Data Warehouses.
to enable data separation relating to the task area, on the one hand, and to be able to perform analyses of the state of the entire dataset on the other.
to make it possible to have fewer complexities when constructing and implementing a Data Warehouse.
to construct hub and spoke scenarios in which a BW System stands in the middle and the data from distributed systems runs together and is standardized.

Integration

Data marts are found both in the maintenance and in the definition, the same as in the SAP source system. Here too, you can group together data from one or more source systems in a BW System, or continue to work in several BW Systems.

Features

These functions can produce different architectures in a Data Warehouse landscape.

Replicating architecture:

If you select this architecture, the data for a BW server is available as source data and can be updated in further target BW systems.

Aggregating Architecture:

With aggregating architecture, data is grouped together from two or more BW servers, and is then available for further processing.
