management system. A Java Clob object (Java type, java.sql.Clob) corresponds to
the SQL CLOB data type.
client
A software process, hardware device, or combination of the two that requests services
from a server. Often, the client is a process residing on a programmable workstation and
is the part of a program that provides the user interface. The workstation client might also
perform other portions of the program logic. Also called a requester.
command
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 Packages
The required set of APIs in a Java platform edition which must be supported in any and
all compatible implementations.

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.
