| 3 | Base tables that have a unique constraint but not the primary key | A common style is to declare in each base table one of the candidate keys as the primary key. All the other candidate keys would be alternate keys that will be enforce with the help of UNIQUE + NOT NULL constraints. | Problem detection | INFORMATION_SCHEMA only | 2021-02-25 17:30 | MIT License | |

Make sure that naming of these is consistent, i.e., such names always contain the table name or never contain the table name. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-01-14 20:53 | MIT License | |

| 17 | Database object that do not belong to the public interface (virtual data layer) and that names contain the letters õäöüÕÄÖÜ | Find database object that do not belong to the database public interface (virtual data layer - consists of routines and derived tables) and that names contain the letters õäöüÕÄÖÜ (Estonian letters with a diacritic). These letters belong to the Estonian alphabet but do not belong to the ASCII character set. Although permitted by the DBMS, such letters might make the naming style inconsistent with the naming style of elements that belong to the public interface. If applications access base tables directly, then the letters can cause the same problems as in case of derived tables, i.e., applications may have difficulties with such names. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:30 | MIT License | |
