What is aggregate object with respect to ABAP Dictionary?

Views, matchcodes and lockobjects are called as aggregate objects since they are formed using several related tables.

Views avirtual table tailored to the needs of an application is needed, making it possible to

directly access specific data.

Matchcodesis a tool to help you search for data records in the system. Matchcodes are an

efficient and user-friendly search aid for cases where the key of a record is unknown.

Lock objects: Simultaneous accessing of the same data record by two users in the SAP system is synchronized by a lock mechanism. When dialog transactions are programmed, locks are set and released by calling certain function modules. These function modules are generated automatically from the definition of so-called lock objects in the ABAP/4 Dictionary.
