Schema Evolution publication categorizer

Changes in the real world may require both the database population and the database schema
to evolve. Particularly, this is the case in CAD/CAM and CASE database systems, in which the
design objects constantly evolve in every aspect. On the other hand, the prototyping of a
database design may also involve changes to both the structure and behavior of a schema.
Unfortunately, most of the current systems offer little support for schema evolution. In this
paper, we survey the recent development of the research in the schema evolution of objectoriented
databases. The main issues in the current research are identified.
