Integrating applications

requirements

• Application coupling: applications should minimize their dependencies on each other so they can evolve without causing problems to others.
• Data timeliness: minimize time between ona application sharing data and other receiving it.
• Data or functionality: not share data but also functionalities, due to it provides a better abstraction between them
• Reliability: Reliable and asynchronous communication allows source application do other work
