System Analysis and Design

Programmer focuses and concentrates on one module only.

Process is represented in circles that convert data into information. But sometimes, it is represented by rounded edged rectangles.

Cost benefit analysis is a part of feasibility study phase.

All of the above options are correct. They refer to transfer of applications from one PC to another.

Feasibility study is the determination of whether the project is worth of doing it or not.

All of the above are the types of coupling used for measuring interconnections of modules like tight coupling, loose coupling, etc.

Decision tables are tabular techniques used for defining logical rules. Decision tables are non-procedural process specification tools, which are used to make a model a complex decision making process.

Data about data is called meta data and collection of meta data is called as data dictionary. Data dictionary is complete listing of data elements pertaining to the system.

Decision tree, decision table and structured english are used to describe control logic.

Flow chart is a graphical presentation of the movement of data from a point of origin to a specific end poin. It looks like rope map in which programmer will use to write a code.

 Prototype gives us sample of the project , preview of project .

 Prototype gives us sample of the project , preview of project .

All of the above options are correct. 

The above are three basic reasons of white box testing, like logical errors, incorrect assumptions and more .

Data element is the smallest unit of data because it will not provide further decomposition.

Both recovery and performance testings are parts of system testing. Therefore, option 4 is correct.

Audit controls protects a system from external security breaches and internal frauds or embezzlement.

  Content coupling - Common coupling - Control coupling  - Stamp coupling - Data coupling

Feasibility document tells whether a project can be done or not.

Fact finding is the first step in the initial investigation. Fact finding means learning as much as possible the present system.

Black box is a process with known inputs, outputs and functions but not internal mechanism.

End user interaction is must because with client or user, problems are solved easily.

Module testing is a first step of testing phase in the SDLC because it is better to execute and test the whole module then go through the next.

Decision table defines logical rules hence it describes condition logically.
