Abstract: A method and apparatus are provided for converting a non-versioned schema to a version-enabled schema. The method includes reading a first set of table definitions that belong to the non-versioned schema. A second set of table definitions is generated for the version-enabled schema such that each table definition in the second set of table definitions corresponds to a table definition in the first set of table. Each table definition in the second set of table definitions includes columns that correspond to the columns of the corresponding table definition in the first set of table definitions and one or more additional columns for storing version information. Multiple versions of a particular object are stored within the table. In response to a request from a user to retrieve the particular object, a version of the particular object to present to the user is determined based on a workspace associated with the user.
