The subject matter of this disclosure can be implemented in, among other things, a device that includes processors, a data repository, and a table version module configured to create a first version of a database within the data repository using a first version of a database schema that defines a set of tables for the database, and receive a result that is responsive to a command, such that when the result indicates a success condition, execution of the command allows access to data contained in the database and verification of the database schema version, wherein the result does not include database schema version information. The device further includes means for executing the command to access the data, wherein the command includes one or more encoded table names, and wherein each of the encoded table names included in the command is generated based on at least a database schema version identifier.
