System and method for integrating and accessing multiple data sources within a data warehouse architecture

摘要: A system and method is disclosed for integrating accessing multiple data sources within a warehouse architecture. The metadata formed by the present provide way to declaratively domain specific knowledge, obtained analyzing sources, in consistent useable way. Four types of information are represented metadata: abstract concepts, databases, transformations mappings. mediator generator automatically generates management computer code based on metadata. resulting defines translation library class. provides representation knowledge warehouse, including “get” “set” methods attributes that call transformation derive value an attribute if it missing. class take “distinguished” high-level objects as input traverse their structures enter into warehouse.
