Connection to and disconnection from HiRDB

Connection to the HiRDB system: Becoming able to access a HiRDB database by means of a UAP is called connection to HiRDB. Connection must be made to the HiRDB system before a transaction can be started. Connection to HiRDB is defined with the CONNECT control SQL statement.

Disconnection from the HiRDB system: Terminating access to the HiRDB database by the UAP and disconnecting from the HiRDB is called disconnection from HiRDB. When disconnection from HiRDB occurs, transactions are terminated and a synchronization point is set. Disconnection from HiRDB is defined with the DISCONNECT control SQL statement.
