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.

Web Services Adapters

Existing internal systems will most likely also need a router or an Enterprise Service Bus (ESB).

by with David Dick

This is a guide for the savvy manager who wants to capitalize on the wave of change that is occurring with Web Services, service-oriented architecture, and—more recently—Cloud Computing. The changes wrought by these technologies will require both a basic grasp of the technologies and an effective way to deal with how these changes will affect the people who build and use the systems in our organizations. This book covers both issues. Managers at all levels of all organizations must be aware of both the changes that we are now seeing and ways to deal with issues created by those changes.
