Effect of Web Services
Unify disparate interfaces
Replace them with XML interfaces
- All systems are seen as either XML producers or XML consumers
Existing systems can be “wrapped” to expose APIs as Web Services
- No changes in the internal code should be necessary
New systems can be coded as Web Services
- Their addition should not disturb existing systems
Notes:
Web Services unifies disparate system interfaces and replaces them with XML interfaces. All systems can now be seen uniformly as either XML producers or XML consumers.
Existing systems can be easily “wrapped” to expose their APIs as Web Services. No changes in the internal code should be necessary.
New systems can be coded as Web Services from the ground up and their addition should not disturb existing systems.
