A lot of RDBMS support some way of commenting on stored objects. For instance, Oracle has this syntax:
COMMENT ON <object> IS 'some comment'
This is very useful when navigating an unknown schema, for instance to explain the meaning of a column with some encoded values, etc. Also, there is tool support when these comments are exposed through the dictionary views and/or through JDBC's DatabaseMetaData
I personally prefer Oracle's syntax over e.g. MySQL's (inline comments in CREATE TABLE) or SQL Server's (some system function).
Ideally, all objects can receive comments, including:
- Tables (and views, etc.)
But I think the most important ones are tables and columns
