Too generic names (foreign key columns)

Query goal:

Find foreign key columns with the names like id, identifikaator, code, kood, number, etc. The names should have a prefix or a suffix that describes the nature of relationship with the referenced table or at least referes to the referenced table. These are too generic names.

Query type:

Problem detection (Each row in the result could represent a flaw in the design)

Query reliability:

Medium (Medium number of false-positive results)
