An Application Programmatic Interface (API) is a logical grouping of external process routines. The Oracle HRMS strategy delivers a set of PL/SQL packaged procedures and functions that together provide an open interface to the database. For convenience we have called each of these packaged procedures an API.Fundamental to the design of all APIs in Oracle HRMS is that they should provide an insulating layer between the user and the data-model that would simplify all data-manipulation tasks and would protect customer extensions on upgrade. They are parameterized and executable PL/SQL packages that provide full data validation and manipulation.The API layer enables us to capture and execute business rules within the database - not just in the user interface layer. This layer supports the use of alternative interfaces to HRMS, such as web pages or spreadsheets, and guarantees all transactions comply with the business rules that have been implemented in the system. It also simplifies integration of Oracle HRMS with other systems or processes and provides supports for the initial loading.
