Catalog Table Permit For Free

A table catalog is a collection of mapped user tables. Administrators can create and load table catalogs and perform other operations to make table catalogs available to Unica Campaign users.

The catalog tables describe such things as table spaces, tables, columns, indexes, privileges, application plans, and packages. Authorized users can query the catalog; however, it is primarily intended for use by Db2 and is therefore subject to change. All catalog tables are qualified by SYSIBM.

Catalogs are named collections of schemas in an SQL-environment. An SQL-environment contains zero or more catalogs. A catalog contains one or more schemas, but always contains a schema named INFORMATION_SCHEMA that contains the views and domains of the Information Schema.

Each database contains one or more SCHEMAs, which again, are each just a label/name. Each schema contains the actual database objects (tables, views, UDFs, file formats, sequences, and so on). There is an INFORMATION_SCHEMA catalog associated with each database, and it is represented as a schema itself.

Tip: When you update the Db2 catalog level, you can specify either the target function level or the catalog level. If you specify the function level, Db2 determines the appropriate target catalog level, and the CATMAINT utility completes any required catalog level updates in sequential order.

A library catalog allows you to search for items owned by a specific library, including books, movies, journals, magazines, music scores, government documents, and more. Library databases allow you to efficiently search for published information such as magazine, journal, and newspaper articles.

Tables catalog view returns the columns that are specific to tables and also all the columns that the sys. objects catalog view returns. The sys. objects catalog view returns rows for objects other than tables, such as stored procedures and views.
