A process that checks if a system aligns with its design specifications.

Ensuring that the software meets the intended design and architecture.

Guidelines that ensure consistent coding practices across a project.

The process of verifying the system meets the needs of its users.

A discipline for maintaining the performance of a system during changes.

The process of modifying and updating software after its initial deployment.

Software maintenance often requires a longer time for activities compared to development.

Modifications in software maintenance must work with existing systems and structures.

Testing to ensure that new changes do not negatively affect existing functionality.

Having appropriate data for testing is crucial during maintenance activities, unlike development.

Regular maintenance activities to prevent software failures.

The primary goal is to prevent future software failures.

Improving how users interact with software, but not the primary goal of preventive maintenance.

Adjustments made to meet changing user needs, separate from preventive maintenance.

Fixing bugs or errors in software, distinct from preventive maintenance.

A diagram that displays dependencies among software components.

A graphical representation of the distribution of numerical data.

A diagram that shows the structure and relationships of an organization.

A diagram that illustrates a process sequence or workflow.

The external interface of a wrapper includes essential interactions with other components.

A software maintenance approach that involves making rapid changes directly to the code without prior investigation.

A model for software maintenance that incorporates minor changes in small cycles.

A model in software maintenance that emphasizes the reuse of existing code or components.

The process of analyzing and understanding code before making changes.

The process of redesigning a system to improve performance and capabilities.

Transforming the database schema to a new structure or format.

Updating or translating existing programs to work on new systems.

The process of converting data from one format to another.

Interfaces that allow specific functions to be called in a wrapped entity.
