A system and method for synchronizing database changes in an enterprise portal application. The system has a cache storing cache data having table data and index data of one or more databases. A schema layer generates schema objects representing the schema of the databases of the cache data. A change management system and a schema layer validates a cache of one or more databases and synchronizes the cache data to the databases by receiving a changeset, comparing the changeset to the schema data, verifying that the changeset is compatible with the cache data and the schema data, and passing the changeset to the cache for updating the cache data or for refreshing the schema data by the schema layer.
