Abstract
In this chapter, an Automatic Schema Evolution Framework is explored and developed to more effectively manage schema evolution in a FSDBS. This framework provides a Schema Element Dependency Meta-Model, a set of Schema Change Templates, and incorporates view generation, view rewriting, and query rewriting as solutions. These developed methods ensure applications can accommodate schema changes and hence remain valid.
