Enterprise Application Integration

Modern enterprises use a number of systems


Customers don't care about systems... they expect service to be delivered.


Integration is the solution


EAI seeks to provide efficient, reliable and secure data exchange between multiple enterprise applications


Types of integration:● Information portals● Data replication● Shared business functions● Service-oriented architecture● Distributed business processes● Business-to-business integration


Fundamental challenges:● Networks are unreliable● Networks are slow● Any two applications are different● Change is inevitable


Main integration approaches:● File Transfer● Shared Database● Remote Procedure Invocation● Messaging


File Transfer: ● simplest form of integration● suitable for infrequent updates


Shared Database:● fast data exchange● requires strict team cooperation


Remote Procedure Invocation:● applies the principle of encapsulation by

hiding data to maintain their integrity● Web Services using standards as SOAP


Messaging:● high-speed● asynchronous ● reliable

Simplest messaging includes following 5 steps:


Why use Messaging:● it is more immediate than File Transfer● better encapsulated than Shared Database● more reliable than Remote Procedure Call


Specific benefits:● remote communication between separate

applications● send-and-forget communication● store-and-forward


Challenges:● Complex programming model● Sequence issues● Synchronous scenarios ● Performance
