SQL system catalog

A relational system uses a  system catalog to store store schema information, such as details about tables and columns, and system views to present internal bookkeeping information. The MonetDB SQL system catalog is a collection of regular readonly tables and views. The relations are modified indirectly through a SQL commands. The system views are implemented as table producing functions.

Below you find a synopsis of the tables and views currently provided. In addition, graphical user interfaces, such as SQuirreL, can be used to interactively browse their content.
