Catalog Store

The catalog store contains the metadata for the IQ database.

Metadata describes the layout of IQ tables, columns, and indexes. The catalog store is sometimes referred to simply as the catalog.

The SYSTEM dbspace – IQ catalog dbspace SYSTEM contains metadata for your IQ database, stored in the same format as tables in a SQL Anywhere relational database system. SQL Anywhere can exist with or without IQ. You may have SQL Anywhere-style tables in your catalog store along with your IQ tables, or you may have a separate SQL Anywhere database. Each catalog dbspace contains exactly one file.
Other catalog dbspaces – you can create SQL Anywhere tables in a separate dbspace from the SYSTEM dbspace.

You can preallocate space to your catalog store by executing an ALTER DBSPACE statement.
