 ILE Component Programming Reference 

 Presented by

Ric Slaten of Countrywide Home Loans 

This presentation will show you how the Integrated Language Environment (ILE) components such as procedures, service programs and binding directories can be used to implement an N-tier developed application.

The ILE supports a component based methodology which may be used by a developer to implement an N-Tier application. The 3-Tier architecture methodology for application development consists of a presentation layer (GUI), a business layer (Business logic), and a data layer (Business rules excluded). The ILE techniques used for the project include Prototypes, Procedures, Service Programs, Binding Directories.

This presentation will also demonstrate how to create and utilize prototypes, procedures, service programs, and binding directories.

The examples contained herein are taken from a major mortgage company’s proprietary source code and will not contain the GUI and business logic layers.
