True

Abstract Class :

In object-oriented programming, a class designed only as a parent from

which sub-classes may be derived, but which is not itself suitable for instantiation.

Often used to

"abstract out" incomplete sets of features which may then be shared by a group of

sibling sub-classes which add different variations of the missing pieces.

ACM : Association for Computing Machinery

Active object : Active object An object that encompasses its own thread of

control.

Activity Diagram :

Depicts high-level business processes, including data flow, or to model

the logic of complex logic within a system.

Actors :

An actor is a person, organization, or external system that plays a role in one or

more interactions with your system. Actors are drawn as stick figures.

API : API (Application Program Interface)

APP : AAP The Association of American Publishers: engaged in standardisation

efforts in

document preparation

Association : Associations between actors and use cases are indicated in use case

diagrams by solid lines. An association exists whenever an actor is involved with an

interaction described by a use case. Associations are modeled as lines connecting use

cases and actors to one another, with an optional arrowhead on one end of the line.

Byte : Byte A data unit of several bits smaller than a computer word: usually 8

bits.

Cache :

Cache A small fast memory holding recently-accessed data, designed to speed up

further access

CAUSE :

CAUSE An international (mainly North American) nonprofit association for

managing and using information technology in higher education

CMM : CMM (Software Capability Maturity Model)

Composability :

Ability to compose systems from plug-and-play components

COMSOFT : COMSOFT Consortium for the Management of Emerging Software

Technologies

COTS :

COTS (commercial off-the-shelf software)

DLL : DLL (dynamic link library)

Evolvability : Support for new capabilities or ability to exploit new technologies

Functional Requirement :

Functional requirements describe the functionality of the product.

They describe exactly what tasks the software must perform. Functional

requirements define the scope of the system, the product boundaries, and its connections

to adjacent systems. Functional requirements also define the business rules. Business

rules are the rules that the system must conform to, based on the individual business. This

includes defining the data that must be

tracked. The business rules are the most important type of functional requirements

and most of your requirements will be of this type.

ISO : ISO (International Standards Association)

JAD : JAD (Joint Application Development)

Localizability :

Ability to make adaptations due to regional differences

Modifiability : Ability to add (unspecified) future functionality

Non-Functional Requirement :

Non-Functional requirements describe the look and feel of

the system. This includes the visual properties of the system, its usability, and the

performance requirements – how big, how fast, etc. Non-Functional requirements also

include the product‘s intended operating environment and any maintainability, portability

and security issues. Non-Functional requirements also include cultural and political

issues as well as legal requirements that the software must conform to.

OOA : OOA (object oriented analysis)

OOD : OOD (object oriented design)

OOP : OOP (object oriented programming)

Quality :

Quality is the degree of match between the product requirements (stated or

otherwise) and the actual product. It is defined from the point of view of the

user‘s perception, expectation and goals or need.
