JDBC Type 4 Driver Programmer's Reference

The operation demanded by an operator or program; a demand for action by, or
information from, a subsystem. A command is typically conveyed as an interprocess
message from a program to a subsystem.
concurrency
A condition in which two or more transactions act on the same record in a database at the
same time. To process a transaction, a program must assume that its input from the
database is consistent, regardless of any concurrent changes being made to the database.
TMF manages concurrent transactions through concurrency control.
concurrency control
Protection of a database record from concurrent access by more than one process. TMF
imposes this control by dynamically locking and unlocking affected records to ensure that
only one transaction at a time accesses those records.
connection pooling
A framework for pooling JDBC connections.
Core API
The minimal set of APIs that developers can assume is present on all delivered
implementations of the Java Platform when the final API is released by Sun
Microsystems, Inc. The NonStop Server for Java 4 conforms to every Core API in the
JDK. Core API is also called Java Core Classes and Java Foundation Classes.
D
Data Control Language (DCL)
The set of data control statements within the SQL/MP language.
Data Manipulation Language (DML)
The set of data-manipulation statements within the SQL/MP language. These statements
include INSERT, DELETE, and UPDATE, which cause database modifications that
Remote Duplicate Database Facility (RDF) can replicate.

driver
A class in JDBC that implements a connection to a particular database management
system such as SQL/MP. The NonStop Server for Java 4 has these driver
implementations: JDBC Driver for SQL/MP (JDBC/MP) and JDBC Driver for SQL/MX
(JDBC/MX).
