A new DB2 tutorial, called eVideoCentral, is available for download at http://www.ibm.com/software/data/developer/samples/evideo. The purpose of the DB2 eVideoCentral tutorial is to give an example solution for a company that provides business services to another company over the web. This concept is known as a Business-to-Business application. The e-VideoCentral tutorial demonstrates the integration of DB2, WebSphere, and MQSeries.
Many technologies are used to design and build eVideoCentral, including: the IBM WebSphere Application Server, VisualAge for Java, and the DB2 XML Extender interaction tool. A set of centralized services for individual retail video stores is accessed via SOAP ( see Simple Object Access Protocol at http://www.w3.org/2000/xp/).
SOAP is a lightweight protocol for exchanging information in a decentralized, distributed environment. It is an XML-based protocol that consists of three parts:
SOAP services can provide a mechanism for one company to access DB2 services from another company.
The eVideoCentral tutorial demonstrates the design, development, and implementation of simple data repository (insertion/modification) and query services. The query services use the existing DB2 XML Extender. The first version of eVideoCentral is provided via the web, and it includes: Java Servlets, JSP (Java Server Pages), schema for the DB2 database objects, and the accompanying tutorial documentation.
