As an integrated development environment (IDE), Designer can be used to create business integration solutions. Within the architecture of Integration Server, each item in the Package Navigator view of Designer is referred to as an element. The term element also applies to packages and folders, but because the VCS Integration feature treats packages and folders slightly differently than other elements, the terms package and folder are used explicitly throughout this guide. The term element is used to refer generally to services and other items contained within a folder in a package, such as document types, schemas, triggers, rule services, and web service descriptors.
