Integration component libraries Integration component libraries are structural groupings of components in your development environment. You define a library in System Manager and System Manager creates a directory in the file system that represents the library. Within the library directory is a number of subdirectories for each type of integration component. When you create an integration component, System Manager creates a file or group of files and stores them in the proper subdirectory within the directory of the library. User projects User projects are structures within System Manager that support the need to organize integration components together so that they are viewed as belonging to an interface. User projects are collections of shortcuts to integration components in one or more libraries, so you can create one user project for each interface. Each user project might have shortcuts to some of the same components in a library because interfaces frequently share components. A customer synchronization interface and an order processing interface that both involved the SAP application, for instance, would both require the Adapter for SAP, so the user projects that correspond to those interfaces would both have shortcuts to the definition for the SAP connector. InterChange Server Express instances InterChange Server Express is an integration broker. It is the software infrastructure that provides business process integration and automation. When you install InterChange Server Express on a computer and start the server, you start a server instance. A server instance hosts the business integration system that is comprised of all the interfaces that satisfy the integration requirements of the customer. Typically you will have one instance of InterChange Server Express dedicated to developing and testing the business integration system as a whole, and one instance for hosting the production release of the system. Stages in developing an implementation Typically, the development of a business integration system involves the following stages: v "Discovery and assessment of requirements" v "Preparation of environments" on page 24 v "Design" on page 24 v "Development and configuration" on page 25 v "Validation" on page 26 v "Deployment" on page 27 Discovery and assessment of requirements This stage begins the implementation process by identifying the business goals for the project, the system requirements, and the overall scope of the development effort. The process of requirements elicitation is very specific to different organizations. This section presents some of the possible questions you will need to ask, but you should follow whatever method is appropriate for your organization. 22 IBM WebSphere Business Integration Server Express and Express Plus: System Implementation Guide
