how to do a lossless decomposition code example
Example 1: lossless join decomposition
In database design, a lossless join decomposition is a decomposition
of a relation R into relations R1 ,R2 such that a natural join of the
two smaller relations yields back the original relation.
This is central in removing redundancy safely from databases while
preserving the original data.
Example 2: what do we mean by lossless join property in dbms
In database design, a lossless join decomposition is a decomposition of
a relation into relations. such that a natural join of the two smaller
relations yields back the original relation. This is central in removing
redundancy safely from databases while preserving the original data.
