Glossary
A
abstract class In Java, a class designed only as a parent from which subclasses can be derived, which is not
itself suitable for instantiation. An abstract class is often used to "abstract out" incomplete sets
of features, which can then be shared by a group of sibling subclasses that add different
variations of the missing pieces.
American
National
Standards
Institute (ANSI)
The United States government body responsible for approving US standards in many areas,
including computers and communications. ANSI is a member of ISO. ANSI sells ANSI and ISO
(international) standards.
American
Standard Code
for Information
Interchange
(ASCII)
The predominant character set encoding of present-day computers. ASCII uses 7 bits for each
character. It does not include accented letters or any other letter forms not used in English (such
as the German sharp-S or the Norwegian ae-ligature). Compare with Unicode.
ANSI See American National Standards Institute (ANSI).
API See application program interface (API).
application
program
One of the following:
A software program written for or by a user for a specific purpose•
• A computer program that performs a data processing function rather than a control function
application
program interface
(API)
A set of functions or procedures that are called by an application program to communicate
with other software components.
ASCII See American Standard Code for Information Interchange (ASCII).
autocommit mode A mode in which a JDBC driver automatically commits a transaction without the programmer
calling commit().
B
base table A table that has physical existence: that is, a table stored in a file.
BLOB Short for Binary Large OBject, a collection of binary data stored as a single entity in a database
management system. These entities are primarily used to hold multimedia objects such as
images, videos, and sound. They can also be used to store programs or even fragments of code.
A Java Blob object (Java type, java.sql.Blob) corresponds to the SQL BLOB data type.
bytecode
The code that javac, the Java compiler, produces. When the Java virtual machine loads this
code, it either interprets it or compiles it.
C
catalog In Neoview SQL a set of tables containing the descriptions of SQL objects such as tables, views,
columns, indexes, files, and partitions.
class path The location where the Java virtual machine and other Java programs that are located in the
directory search for class libraries (such as classes.zip). Include the hpt4jdbc.jar file in
your class path. The hpt4jdbc.jar file is in the location where you installed this product.
You can set the class path explicitly or with the CLASSPATH environment variable.
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.
CLOB Short for Character Large OBject, text data stored as a single entity in a database management
system. A Java Clob object (Java type, java.sql.Clob) corresponds to the SQL CLOB data
type.
