MC/DC stands for Modified Condition / Decision Coverage, a structural coverage metric used in safety-critical software testing.

Regression testing re-tests modified software to verify that changes or bug fixes have not introduced new defects in existing functionality.

HIPO (Hierarchy plus Input-Process-Output) diagram represents system modules hierarchically, similar to a Structure Chart.

McCabe's Cyclomatic Complexity formula V(G) = e - n + 2p, where e is number of edges, n is number of nodes, and p is number of connected components.

An ER diagram models the static structural conceptual view of data (entities, attributes, and relationships), not dynamic runtime behaviors.
