1.1 Introduction The IBM WebSphere Information Integrator V8.2 portfolio provides the foundation for a strategic information integration framework that helps customers decrease time to market for new applications, get more value and insight from existing assets, and control IT costs. This platform provides a range of information integration capabilities -- enterprise search, data federation, data transformation, data placement (caching and replication), and data event publishing -- designed to meet a diverse range of data integration requirements for business intelligence and business integration. Of particular interest in this redbook are the WebSphere Information Integrator Event Publisher (WIIEP) offerings on the z/OS platform, that capture database changes in DB2 UDB for z/OS, IMS, CA-IDMSTM, Software AG AdabasTM, or VSAM by reading the active or recovery log, format the changes into consistent relational XML messages, and publish them to WebSphere MQ. Any application or service that integrates either with WebSphere MQ directly or supports JavaTM Message Service (JMS) can asynchronously receive the data changes as they occur. WIIEP solutions enable database events to initiate business processes. For example, a change in an inventory value could be used to drive a product restocking workflow, or the addition of a new customer could initiate welcome e-mail, credit verification, and accounting updates. This creates an application-independent, loosely coupled integration that is more adaptable to changing application environments. For example, while multiple applications may impact the value of the inventory level, a single point of integration -- the data items themselves -- is driving the workflow. Changes to the applications that impact the inventory level can be made with no impact on the event driven integration. Additionally, WIIEP solutions can deliver changes to Extract, Transform, and Load (ETL)
