Web Services Adapters
Web Services adapters transform message formats. Adapters can connect systems designed for Web Services as well as legacy systems. Adapters can be written in-house or purchased from third-party software vendors. Some examples of systems that could use adapters include:
- Internally developed systems
- Packaged software
- Database systems
- Object Request Brokers (ORBs)
The following figure shows two internal systems using adapters. At the top of the figure is a message format that uses the standard semantic vocabulary adopted by an organization represented in XML. At the bottom left is an internal system that could be running packaged software that expects a different XML message format. At the bottom right is a legacy internal system that uses a fixed record format.
