Software Requirements

Question 1

Define a requirement

Answer 1

A requirement is a specification of what should implemented, it drives the design choices that need to be made, as well as describe how the system should behave

Question 2

Requirements gathering is the process of _

Answer 2

Requirements gathering is the process of gathering and documenting the functions that the system should perform for the users, in their language and from their perspective

Question 3

Describe what happens in the analysis phase/activity

Answer 3

During the analysis process, the requirements are taken and built into a logical solution that satisfy the requirements, but does not need to take into account the physical constraints

Question 4

Describe what happens in the design phase/activity

Answer 4

The design phase starts with the logical solution from the analysis phase, changing it to work effectively with the physical constraints, (e.g network latency, database performance, user interface, etc), and transforming it into specifications that can be used during the construction/development phase

Question 5

Describe what happens during the construction phase/activity

Answer 5

The construction phase uses the output of the design phase to produce working code

Question 6

Describe what happens during the testing phase/activity

Answer 6

The product from the construction phase is tested, and issues are detected, recorded and fixed, and user acceptance is acquired

Question 7

Describe what happens during the deployment phase/activity

Answer 7

The tested application is put onto the production environment by deploying the code libraries to the destined machines, training users and fine-tuning the business procedures surrounding the new system

Question 8

Describe what happens during the maintenance phase/activity

Answer 8

Administer and make changes to the working system in the production environment to adapt to ongoing business changes, technology changes, and system issues (bugs, design problems) etc

Question 9

Define UML

Answer 9

UML is Unified Modeling Language, a language notation that governs the ways to document system specifications

Question 10

What does UML do?

Answer 10

UML tells you how to structure your system documentation

Question 11

What are sequence diagrams used for?

Answer 11

Sequence diagrams are used as a tool to illustrate the internal workings of a use case

Question 12

What are collaboration diagrams used for?

Answer 12

Collaboration diagrams are used to illustrate complex interactions of a use case, such as conditional messaging

Question 13

What do state and activity diagrams do?

Answer 13

State and activity diagrams illustrate the transition from one state to another of a system - they illustrate how the state of a program changes in response to input data

Question 14

Describe class diagrams

Answer 14

Class diagrams show how classes are constructed and list their names, attributes, and operations. They also show the relationship between classes

Question 15

Describe object diagrams

Answer 15

Object diagrams show the relationships between objects in the system
