Records in PL/SQL Record types are composite data structures or groups of data elements, each with its own definition.Records can be used to mimic the row structures of tables and cursors, or as a convenient way to pass data between subprograms without listing large number of parameters.Since the package specification defines the interface to the package, the implementation within the package body can be modified without invalidating any dependent code, thus breaking complex dependency chains.A call to any element in the package causes the whole package to be loaded into memory, improving performance compared to loading several individual procedures and functions.When a record type must match a particular table or cursor structure, it can be defined using the %ROWTYPE attribute.
