The catalog contains system tables that link together by keys and indexes. In SQL Anywhere, the system tables are hidden. However, there is a system view for each table. In some cases, a system view may also include columns from more than one system table, to satisfy a commonly needed join.

To ensure compatibility with future versions of the SQL Anywhere catalog, make sure your applications make use of system views and not the underlying system tables, which may change.
