CI adopts 4 methods in integrating different solutions to the base product. Each method is dependent on the framework of the base product that provides facilities to integrate. I have already posted about the other methods: API, Direct Data Level Connectivity and Screen Scrapping

Full Access Method is an extension of the API method that has full access to the source code of the systems being integrated. CI has used this method for integrating various solutions with Sage PRO ERP. The teams used Sage PRO tools and FoxFire tools for the integration.
