3.3.1 Systematic Approach To Problem Solving

Question 1

Stages of Software Development

Answer 1

• Analysis
• Design
• Implementation
• Testing
• Evaluation

Question 2

Analysis

Answer 2

Where the problem is defined and system requirements identified.

Question 3

Data Model

Answer 3

Abstract model organizing data items, their relations to one another and the real world entities they represent.

Question 4

Design

Answer 4

Where the algorithms data structures and user interface are designed.

Question 5

Factors taken into consideration during design

Answer 5

Data input
Processing
Output
Security
Hardware considerations

Question 6

Modularity

Answer 6

Decomposing the functionality of a program into modules (independent components)

Question 7

Implementation

Answer 7

Where the actual code and data structures are written and developed according to the agreed upon specification to create a prototype

Question 8

Testing Types

Answer 8

Boundary Test Data - Testing edge cases of the acceptable data as an input
Erroneous Test Data - Using data that is out of range as input
Normal Test Data- Testing data that is acceptable

Question 9

Testing

Answer 9

System tests for errors and inconsistencies with the prototypes using the design specifications through different input data and scenarios.

Question 10

Evaluation

Answer 10

Where the system is critically judged and reviewed with the user specification and judged based on its performance and effectiveness.
