Schema transformation without database reorganization
1993
SIGMOD record
We argue for avoiding database reorganizations due to schema modi cation in object-oriented systems, since these are expensive operations and they con ict with reusing existing software components. We s h o w that data independence, which is a neglected concept in object databases, helps to avoid reorganizations in case of capacity preserving and reducing schema transformations. We informally present a couple of examples to illustrate the idea of a schema transformation methodology that avoids database reorganization.
