Software Development Life Cycle (SDLC)

Flashcards covering key terms and concepts related to software development life cycle and related processes.

Software Development Life Cycle (SDLC)

A process for planning, creating, testing, and deploying software.

Alpha testing

Testing of software conducted by internal employees.

Beta testing

Testing of software conducted by clients at the client location.

White box testing

Testing that allows the tester to see the code and evaluate all lines of code.

Black box testing

Testing that focuses on outputs instead of the internal workings of the software.

User acceptance testing

Evaluation to see if the system meets the client’s expectations or requirements.

Direct change/big bang

Completely replacing the old system with a new one; the easiest but riskiest method.

Pilot implementation

Installing the new software on a few computers to check functionality before full deployment.

Phased implementation

Gradually upgrading different aspects of the system on various computers.

Parallel implementation

Running both old and new software simultaneously, the safest but most costly method.

Corrective maintenance

Fixing bugs or issues in existing software.

Adaptive maintenance

Making changes to accommodate new requirements not in the original design.

Perfective maintenance

Improving software for better performance and user experience.

User documentation

Reference guide that helps users understand how to use a system.

Help files

Accessible documentation providing instructions on usage and troubleshooting after installation.

Removable media

Physical devices like USB drives or CDs that can transfer data externally.

Failover system

Automatically switches to a backup in case of failure.

Data migration

The process of transferring data between storage types, formats, or systems.

Legacy systems

Older computer systems still in use that may present compatibility issues.

SaaS (Software as a Service)

Cloud-based software that can be accessed from anywhere with internet.

Release

A completely new software version with major updates.

Patch

A fix made to a specific part of the software addressing glitches.

Server

Any device providing data or resources to a client.

Firewall

A system that protects networks by controlling incoming and outgoing traffic.

Client-server model

A model where client devices request resources from a server.

Usability

The ease with which users can learn and use a system.

Accessibility

The design of products to be usable by people with disabilities.

Stakeholders

Individuals or groups that have an interest in a company's product or service.

Interviews

A method of gathering information by directly asking individuals.

Surveys

A method of collecting data from a large group of people efficiently.

Data flow diagrams

Visual representations describing how data moves through a system.

Prototypes

Models of systems used to gather user feedback and improve designs.

Iterative design

The process of repeating cycles of design and testing to improve the product.

Social and ethical issues

Concerns related to the implications of technology on society.

Change management

Processes to ensure smooth transitions when implementing new systems.
