Version control is a system that manages modifications to source code over time. It allows developers to track and revert to earlier versions, collaborate effectively, and manage code repositories. Integration testing is a software program testing technique that checks the interaction and integration between different components or modules of a software system.
Data construction centered design. A structured software program design approach wherein the structure of a system is derived from analysis of the construction of the info sets with which the system should deal. (ISO) (1) A string of records, words, or characters that for technical or logical functions are handled as a unity. (2) A collection of contiguous data which may be recorded as a unit, and the models are separated by interblock gaps. (3) A group of bits or digits that are transmitted as a unit and that might be encoded for error-control purposes. In FORTRAN, a block may be a sequence of statements; in COBOL, it might be a physical report.
