A UDDI registry node consists of the following elements:
- A J2EE application.
- A store of data that is referred to as the UDDI database. The UDDI database uses a relational database management system.
- A way to connect the application to the data (a data source and related elements).
All the data that relates to UDDI is stored in the UDDI database and therefore that data exists, regardless of the UDDI application. Therefore, you can remove a UDDI registry node from the application server without deleting the database, then reinstall the UDDI registry application. You might do this if an application is corrupted, or to apply service changes.
