The database command rewriting system rewrites a first database command that includes language specific for a first database management system command into a second database command suitable for a second database management system. The database command rewriting system receives the first database command and identifies the specific language. Furthermore, the database command rewriting system retrieves a rule based on the identified language. Using the retrieved rule, the database command system rewrites the first database command to the second database command and transmits the second database command to the second database management system.
