摘要
The dependency preserving and lossless join properties for relational database decomposition are generalized to the constraint preserving and lossless properties for mappings between database systems. The constraint preserving and lossless properties are investigated both for relational database normalization by decomposition and for relational database distribution by selection. The constraint preserving and lossless properties are also discussed for mappings between heterogeneous databases.
