Records in the RECON data sets

The RECON data set contains many types of records. Some records, such as header records, exist primarily to control processing of the RECON data set. Other records exist to define the various data sets used in the recovery of DBDSs. Still others exist to record events related to the use of DBDSs.

The following figure shows the major relationships between RECON record types. These relationships are described in detail in the topics that follow the figure.
