Unit 12 Section 7: Definition Process and Partition Selection

This video describes the definition process (DBDGEN) for HALDBs. The DBDGEN creates the HALDB “master” DBD. The logical structure of the database includes the relationship between the segments, the pointers used, the database access method (PHDAM or PHIDAM), the segment layouts, the database physical data set organization (VSAM or OSAM), and, if appropriate, any secondary indexes.
