There are many problems associated, when we upgrade our product database schema to next version. Many times it is found that there
is data corruption or we find that data integrity and consistency is lost. There are many solutions/methods, but each method has its own
drawback to overcome these problems. We have suggested an incremental methodology to upgrade a database schema from one version to next
version having no data corruption and maintaining the database consistency and integrity.

Keywords: schema upgrade, schema migration, Schema Evolution, Object database, schema integration.
