Glossary

ActiveX ActiveX is the name Microsoft has

given to a set of strategic, object-oriented

programming technologies and tools. The

main technology is the Component Object

Model (COM). Used in a network with a

directory and additional support, COM

becomes the Distributed Component Object

Model (DCOM). The main thing that you

create when writing a program to run in the

ActiveX environment is a component, which is

a self-sufficient program that can be run

anywhere in your ActiveX network (currently a

network consisting of Windows and Macintosh

systems). This component is known as an

ActiveX control. ActiveX is Microsoft's answer

to the Java technology from Sun

Microsystems. An ActiveX control is roughly

equivalent to a Java applet.

BS7799 British Standard 7799, a document

describing enterprise security.

CA A Certificate Authority is an authority in a

network that issues and manages security

credentials and public keys for message

encryption. As part of a public key

infrastructure (PKI), a CA checks with a

Registration Authority (RA) to verify

information provided by the requestor of a

digital certificate. If the RA verifies the

requestor's information, the CA can then issue

a certificate.

CORBA Common Object Request Broker

Architecture is an architecture and

specification for creating, distributing, and

managing distributed program objects in a

network. It allows programs at different

locations and developed by different vendors

to communicate in a network through an

interface broker. CORBA was developed by a

consortium of vendors through the Object

Management Group, which currently includes

over 500 member companies. Both the

International Organization for Standardization

(ISO) and X/Open have sanctioned CORBA

as the standard architecture for distributed

objects (which are also known as

components). CORBA 3 is the latest level.

Canadian government.

DMZ A demilitarized zone is an area of your

network that separates it from other areas of

the network, including the Internet.

EJB Enterprise JavaBeans is an

architecture for setting up program

components written in the Java programming

language that run in the server parts of a

computer network that uses the client/server

model. Enterprise JavaBeans is built on the

JavaBeans technology for distributing program

components to clients in a network. Enterprise

JavaBeans offers enterprises the advantage of

being able to control change at the server

rather than having to update each individual

computer with a client whenever a new

program component is changed or added. EJB

components have the advantage of being

reusable in multiple applications. To deploy an

EJB Bean or component, it must be part of a

specific application, which is called a

container.

J2EE Java 2 Platform Enterprise Edition is a

Java platform designed for the

mainframe-scale computing typical of large

enterprises. Sun Microsystems, together with

industry partners such as IBM, designed J2EE

to simplify application development in a thin

client tiered environment.

JDBC Java Database Connectivity is an

application program interface (API)

specification for connecting programs written

in Java to the data in popular databases. The

application program interface lets you encode

access request statements in the structured

query language (SQL) that is then passed to

the program that manages the database. It

returns the results through a similar interface.

JDBC is very similar to the SQL Access

Group's Open Database Connectivity (ODBC)

and, with a small bridge program, you can use

the JDBC interface to access databases

through the ODBC interface.

JNDI Java Naming and Directory Interface

enables Java platform-based applications to

access multiple naming and directory

services. Part of the Java Enterprise

application programming interface (API) set,

JNDI makes it possible for developers to

create portable applications that are enabled

for a number of different naming and directory

services, including file systems, and directory

services, such as Lightweight Directory

Access Protocol (LDAP), Novell Directory

Services, and Network Information System

(NIS), and distributed object systems, such as

the Common Object Request Broker

Architecture (CORBA), Java Remote Method

Invocation (RMI), and Enterprise JavaBeans

(EJB).

JSP Java Server Page is a technology for

controlling the content or appearance of Web

pages through the use of servlets, small

programs that are specified in the Web page

and run on the Web server to modify the Web

page before it is sent to the user who

requested it.
