In Repository Based Programming, a Repository Contains Input Controls and Code

In repository based programming, a repository contains input controls and code. The developers can, in a single location, define most of the properties and constraints for a reusable field and the data validation code for that field. Once defined, the object or control can be used by any number of other systems analysts and programmers in the organization. This approach guarantees that every instance of the field will be used in a consistent manner. Furthermore, the repository entries can be changed if business rules dictate and no additional changes to the applications will be required.
