The information-sharing environment
Suppose, for an instance, that you are presented with this scenario:
The federal government is building a criminal justice information-sharing system to provide nationwide connectivity to disparate local, state, tribal, and federal systems for the exchange of information. In order to effectively share this disparate information, standardized information exchanges are defined using a government XML Standard defined by the National Information Exchange Model (NIEM). This standard is based upon an extension to the Global Justice XML model (GJXML).
The sharing organizations need effective tools to enable them to share their legacy data using the new, information-sharing standard without requiring a large development effort or a re-writing of their existing systems.
The IBM Information Server (IIS) product suite provides the tools for generating and deploying information services that can be used to access the legacy databases without writing code. Instead, you can perform codeless visual design of data flows using hundreds of built-in transformation functions.
The IIS InfoSphere DataStage and WebSphere Transformation Extender are used to generate a DataStage job that reads the database and transforms the information into a GJXML XML model. Then, the InfoSphere Information Services Director (IISD) component of IIS is used to generate and deploy the Web service without any coding.
