Unit 6: Source Integration

Integration frameworks assist in reducing the complexity of creating, managing and changing notes
integration solution. The advantage is faster time to market through pre built adapters and
reusable integration infrastructure.

process integration

This provides the highest level of abstraction and adaptability for an EAI solution. This enables
managers to define, monitor and change business processes through a graphical modeling
interface.
Business Process Modeling helps business users and analysts to define how information flows
across systems and organizational boundaries through a graphical model and declarative
language instead of programming. The integration solution is generated from the model. When
changes are required, they can be made in the model and the same can be regenerated in the
solution. Simulation can also be done before the implementation of the solution.

6.19 eai implementation

Understanding the organizations business processes and data is essential to select which processes
and data require integration. There are four different scenarios for EAI viz.,
1. Database Linking
2. Application Linking
3. Data Warehousing

4. Common Virtual System
Database Linking

This is basically linking two or more databases so that information is shared between the databases
at some point. The information can be exchanged and duplicate information maintained or
information can be shared. This is the simplest and initial form of EAI.

application Linking

This one is more complex than database linking. Application linking means both processes and
data between two or more applications are integrated. The advantage of this there is redundant
business processes are not created as the processes are shared between applications.

Data Warehousing

This is similar to database linking. Data Warehousing is the collection of meaningful data from
several data sources to support decision-making efforts within an organization. The data from
different data stores is extracted, aggregated and migrated into a data mart or data warehouse.
EAI assists in real time data warehousing.

common virtual system

A virtual system means that for any transaction, the information required for it will be available
irrespective of where the information exists. EAI helps to integrate diverse systems so that they
appear as one monolithic and unified application.
