Data warehousing tool support

In operational practice, data warehouses are big corporate databases that are continuously under development. This implies a dynamic increase of the complexity of the data. For controlling this complexity, a conceptual model driven approach is recommended in order to guarantee that the relation to the business environment can be validated at any moment.

To keep maintainable the connection between the conceptual model and the logical/physical aspects of the data warehouse and related data marts, bridges are needed that can provide the needed model-to-model conversion at any desired moment. To achieve this, a bridge-toolset is designed and developed which is based on a single point of definition metadata philosophy.

The philosophy and the way of working are developed in a research project at HAN University in The Netherlands in co-operation with the Dutch system house Atos Origin to overcome data warehouse life cycle maintenance problems in the Royal Dutch Airlines (KLM).
