When creating Flow services, what is the purpose of a SEQUENCE operation?
The purpose of Sequence operation is to group a subset of Flow operations so that they are treated as a unit.
What Is the Pipeline?
The pipeline is the general term used to refer to the data structure in which input and output values are maintained for a flow service.

What are the Advantages of EAI?
Advantages of EAI solutions are:

How should I organise connection pools?
If you have adapter notifications and adapter services then you will need to have two separate connections. Otherwise you may get strange errors about transactions and the like. You should also avoid having connection pools shared across different functional areas, even if they are pointing to the same database. The reason for this is that tuning the size of the pool becomes quite difficult if you have multiple types of usage of a pool. You are also unable to easily change the database settings for one without impacting on the other. One approach that seems to work quite well is to have separate pools for each package (generally.. not a hard and fast rule though), as your packages should generally be divided up according to functional area too.
What are the disadvantages of EAI?
The main disadvatages of using EAI systems:
i. Constant change: The very nature of EAI is dynamic and requires dynamic project managers to manage their implementation.
ii. Lack of EAI experts : EAI requires knowledge of many issues and technical aspects.
iii. EAI is a tool paradigm: EAI is not a tool, but rather a system and should be implemented as such.
iv. Building interfaces is an art : Engineering the solution is not sufficient. Solutions need to be negotiated with user departments to reach a common consensus on the final outcome. A lack of consensus on interface designs leads to excessive effort to map between various systems data requirements.
v. Loss of detail : Information that seemed unimportant at an earlier stage may become crucial later.
vi. Accountability : Since so many departments have many conflicting requirements, there should be clear accountability for the system’s final structure.
