Q

Implementation:

By Reference Definition

A

The sub-program has direct access to the memory location holding the value. This means any changes to the value being held will be stored.

Q

Implementation:

By Value Definition

A

The sub-program is given a temporary copy of the value being held in the variable. The value can be changed, but this will not be stored

Q

Implementation (sequential files):

What are the file operations?

5

A
  • Create
  • Open
  • Close
  • Read
  • Write
17
Q

Development Methodologies:

What does the iterative process involve?

2

A
  • Programmers move from stage to stage in order, only revisiting stages where necessary and a problem is discovered
  • It is a very structured process and clients are only communicated with at the beginning and end of development
18
Q

What does the agile process involve?

2

A
  • Uses ‘sprints’ which are periods of planned analysis, design, implementation and testing of a particular aspect of software
  • It is a flexible process that is based on team work and daily communicated which is suited to small, short term projects rather than larger scale projects
19
Q

Development Methodologies:

Iterative Strengths

4

A
  • Rigid planning structure
  • Good for large teams
  • Helps to plan and track large software projects
  • Clear agreement on outcomes at start of project
20
Q

Development Methodologies:

Iterative Weaknesses

4

A
  • Very rigid approach does not deal well with mid-project changes
  • Can over-complicate simple projects
  • Unidentified issues at the analysis stage can be time-consuming and costly to gix
  • Little involvement of client after analysis
21
Q

Development Methodologies:

Agile Strengths

4

A
  • Copes well with little cumulative changes as the project progresses
  • Good for small scale projects like most apps
  • Ongoing involvement of client allows changes to be agreed quickly
  • Changes cause less delay or can be tackled in the next version
22
Q

Development Methodologies:

Agile Weaknesses

4

A
  • Works best with small teams
  • Needs close version control and tracking of changes
  • Can be difficult to determine the full scope of the project in the early stages
  • Usually no legally binding agreement at the start
23
Q

Testing:

Reasons for Testing

3

A
  • Identify errors
  • Show that all functional requirements have been met
  • Ensure efficient and maintainable code
24
Q

Testing:

What is a dry run?

2

A
  • When a programmer works through the program on paper following the code line by line to pick up logic errors
  • Often used with trace table
25
Q

Testing:

What is a trace table?

A

Consists of the variables used in a specific programmer and allows the developer to track the values being stored at different points throughout the program

26
Q

Testing:

What is a breakpoint?

2

A
  • A user-defined point in the program where the code will stop executing, and the value of variables can be inspected to ensure they are correct
  • Often used with trace tables
27
Q

Testing:

What is a watchpoint?

2

A
  • A point placed on a specific variable to track any changes in value, program will stop when the value of the variable changes
  • Used with breakpoints to look at the value of only specific variables when a breakpoint is triggered
28
Q

Design:

What is top down, stepwise refinement?

2

A
  • Any main steps from the design are known as the top down design
  • These main steps are usually broken down further into step by step instructions known as stepwise refinements, which helps the programmer break down the program into manageable modules
29
Q

Design:

What are the benefits of a modular solution?

3

A
  • Different programmers can implement different parts of the design
  • Each part of the design can be tested seperately
  • Design shows the main process clearly
30
Q

Evaluation:

What criteria is evaluated in a program?

5

A
  • Fitness for purpose
  • Efficient use of coding constructs
  • Usability
  • Maintainability
  • Robustness
31
Q

Analysis:

What is the role of a systems analyst?

2

A
  • Meeting with the client and discussing their specific needs
  • Creating a detailed project proposal
32
Q

Analysis:

What is the software specification?

A

Defined extent of the software and a legal contract between the client and the developers

33
Q

Analysis:

What is the role of a client in software specifications

A

Legally obliged to pay for the software

34
Q

Analysis:

What should analysis include?

4

A
  • Purpose: a general description of the purpose of the software
  • Scope: a list of deliverables that the project will hand over to the client / user
  • Boundaries: the limits that define what is in the project and what is not
  • Functional Requirements: features and functions that must be delivered by the systems in terms of inputs, processes and outputs
