Answer :

Advantages of EAI answers are:
•Streamlines enterprise methods and helps boost organizational efficiency.
•Real time statistics get admission to among systems.
•Maintains information integrity throughout multiple structures.
•Speedier transactions at reduced expenses.
•If one of the programs misbehaves and requires to be close down for maintenance, then with EAI, we will without difficulty “decouple” it from relaxation of the systems. Which avoids having to bring down different systems.

Question four. What Are The Disadvantages Of Eai?

Answer :

The principal disadvatages of the use of EAI systems:
•Constant alternate: The very nature of EAI is dynamic and calls for dynamic mission managers to control their implementation.
•Lack of EAI professionals : EAI calls for understanding of many issues and technical factors.
•EAI is a device paradigm: EAI isn't always a tool, however as a substitute a device and should be implemented as such.
•Building interfaces is an artwork : Engineering the answer is not enough. Solutions want to be negotiated with user departments to attain a common consensus at the very last final results. A lack of consensus on interface designs leads to excessive attempt to map among various systems information requirements.
•Loss of element : Information that regarded unimportant at an in advance degree may additionally emerge as essential later.
•Accountability : Since so many departments have many conflicting necessities, there have to be clean duty for the machine's very last shape.
