Abstract
Method, system, and programs for heterogeneous data management. Information from multiple data sources is first obtained. Data/metadata from each of the data sources is modeled based on the source and/or granularity information of the data/metadata to generate data/metadata models. The data/metadata from multiple data sources are integrated, by applying one or more processes to the data/metadata from different data sources based on the data/metadata models, to generate integrated data/metadata. A provenance representation for the integrated data/metadata is created tracing sources, granularities, and/or processes applied and archived for enabling an query associated with the integrated data/metadata.
