| 392 | Prefixes in the names of database objects | Find for different types of database objects all the prefixes that are used in different names. One should be consistent in naming, including in the use of prefixes. If you use prefix in the name of a database object, then it could refer to the type of the database object.

| 394 | Coverage by derived tables | Find for each base table the list of derived tables (both views and materialized views) that refer to the base table. If the database is used through the public database interface (virtual data layer), then, ideally, each table is referred from the subquery of at least one derived table. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-11-11 09:31 | MIT License | |
| 395 | Coverage by routines that have the SQL-standard body | Find for each base table the list of routines (functions and procedures) that refer to the base table.
