System Development Methods

Flashcards covering key concepts, definitions, and methodologies related to Information Systems and System Development Methods.

Information Systems (IS)

Interrelated components functioning together to achieve an outcome.

System Development Lifecycle (SDLC)

The entire process consisting of all activities required to build, launch, and maintain an information system.

SDLC Phases

The series of phases to plan, analyze, design, implement, and support an information system.

IS Methodologies

Frameworks used to structure, plan, and control the process of developing an information system.

Stakeholders

People who have an interest in an information system including technical and non-technical workers.

Hardware

The physical components of an information system, including servers, workstations, and telecommunications equipment.

Software

Programs that control the hardware and produce results; includes system software and application software.

Data

The raw material that an information system transforms into useful information.

Processes/Procedures

Tasks and business functions performed to achieve specific results.

Corrective Maintenance

Maintenance focused on repairing faults or errors found in day-to-day system functions.

Preventive Maintenance

Implementing changes to prevent errors from occurring in the system.

Adoptive Maintenance

Adjustments made to help the system adapt to new environments.

Perfective Maintenance

Changes made to add new functionalities to the system.

Waterfall Model

The most basic methodology close to the SDLC.

Rapid Application Development (RAD)

A methodology used for small and fast projects.

Extreme Programming (XP)

A methodology optimal for advanced and heavy coding projects.
