A Set of Quality Indicators and Their Corresponding Metrics for Conceptual Models of Data Warehouses design metrics in which each metric is part of a quality indicator we wish to measure. In this way, our method allows us to define metrics (theoretically validated) that are valid and perfectly measure our goals as they are defined together a set of well defined quality indicators.

Data Mapper: An Operator for Expressing One-to-Many Data Transformationss the optimization of data transformation expressions that combine filters expressed as standard relational operators with mappers. Furthermore, we identify the two main factors that influence the expected optimization gains.
