A relational database is a database that can be perceived as a set of tables and can be manipulated in accordance with the relational model of data. The relational database contains a set of objects used to store, access, and manage data. The set of objects includes tables, views, indexes, and packages.
There is only one relational database on any AS/400 system. It consists of all the database objects stored locally on the AS/400 system. The name of the local relational database can be assigned through the use of the ADDRDBDIRE (Add RDB Directory Entry) command. Other relational databases on other systems can be accessed remotely.
The database manager is the name used generically to identify the AS/400 Licensed Internal Code and the DB2 UDB for AS/400 portion of the code that manages the relational database.
