WJEC Digi Tech - 1.2 - 8: Systems Development Life Cycle (SDLC)

What is the purpose of the Systems Development Life Cycle (SDLC)?

• To describe the stages involved in a project that involves a change to a new system

• To provide a detailed budget for IT projects

• To outline the specific roles of each team member in a project

• To serve as a contract between the service provider and the client

What is the primary focus during the 'Investigation' stage of the SDLC?

• Developing and testing the system

• Conducting a feasibility report

• Planning the project in detail

• Evaluating the overall project

During which stage of the SDLC does the system analyst carry out detailed investigations to fully understand the current system and the plan?

• Investigation and Analysis

• Design

• Implementation

• Maintenance

What is the goal of the 'Design' stage in the SDLC?

• To ensure the system is working correctly and is ready for use

• To look at the overall project and consider how things went

• To plan the project in detail so that the system will meet user requirements

• To continue system support for the lifetime of the system

What is the purpose of a decision table in systems development?

• To create a visual representation of the system's database

• To identify how a system should respond to different sections of actions

• To outline the physical layout of the system's hardware

• To document the personal information of system users

What does a data dictionary typically contain?

• A list of all the passwords for users in the system

• Records about other objects in the database

• The physical dimensions of the database server

• A backup of the database itself

Which phase of the Systems Development Life Cycle does the analysis of system requirements occur?

• Implementation phase

• Analysis phase

• Design phase

• Testing phase

What is a field in the context of a database?

• A set of related databases

• A single piece of information from a record

• A type of data encryption method

• A user interface element

What is a Data Flow Diagram (DFD)?

• The storage location for data

• A model to provide detail of each process in an IT system

• A graphical representation of the user interface

• The documentation of the system's hardware

What is the purpose of testing in computer hardware and software development?

• Determine whether the program meets the needs of the client (user)

• To check the program works properly and identify any errors

• To determine the color scheme of the program

• To assess the speed of the program
