| <p>Database modules provide an abstraction layer for different interfaces |
| used by database management systems for autoincrement columns. The value |
| can be obtained from the DBMS or some other source before or after the statement |
| is executed. Or some code can be inserted into the query to direct the DBMS |
| to use the next value of a sequence.</p> |
