The primary advantage of object-oriented technology is enhanced efficiency due to the re-use of elements of logic. Object-oriented technology is a software design model that uses objects, which contain both data and code, to create modular and reusable programs. Objects can be inherited from other objects, which reduces duplication and improves maintainability. Grouping objects into methods for data access, managing sequential program execution for data access, and managing a restricted variety of data types for a data object are not advantages of object-oriented technology. References: ISACA CISA Review Manual 27th Edition, page 304
