What information does the System Dictionary contain?

Human-readable labels and language settings are managed through `sys_documentation` and `sys_choice` tables or localization files, not solely the System Dictionary itself, although the dictionary underpins their structure.

The System Dictionary contains the complete definition for every table and column in the database, including data types, lengths, default values, and other attributes that define the database schema.

While the System Dictionary defines reference fields that establish relationships, a comprehensive 'information on how tables relate to each other' is often visualized through tools like the Schema Map, not directly contained as a single entry in the dictionary.

The language dictionary for spell checking is a separate linguistic component, not the core function of the System Dictionary, which is database schema definition.
