Architectural design

In transaction mapping the first level factoring results in the

• creation of a CFD

• derivation of the control hierarchy

• .distribution of worker modules

• refinement of the module view

A successful application of transform or transaction mapping to create an architectural design is supplemented by

• entity relationship diagrams

• module interface descriptions

• processing narratives for each module

• both b and c

The software _______ of a program or a computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships among them.

• Design

• Architecture

• process

• requirement

'FAN IN' of a component A is defined as

• Count of the number of components that can call, or pass control, to a component A

• Number of components related to component A

• Number of components dependent on component A

• None of the mentioned

Which of the following statement(s) is/are true with respect to software architecture?

S1: Coupling is a measure of how well the things grouped together in a module belong together logically.

S2: Cohesion is a measure of the degree of interaction between software modules.

S3: If coupling is low and cohesion is high then it is easier to change one module without affecting others.

• Only S1 and S2

• Only S3

• All S1,S2 and S3

• Only S1

Transform analysis is an element of transaction analysis

• True

• false

The overall data flows in sequential manner and follows one, or only a few, “straight line” paths

Info flow has a single transaction node that triggers other data flow

Structured design is a data flow oriented design method

• True

• False

The hub of info flow from which many action paths originate is referred to as

• Transaction

• Transaction centre

• Transaction hub

• All are correct
