notes interfaces

Access to application is through the interfaces. Interfaces interact with the application either
via descriptions they provide to their platforms component model or by taking advantage of
the program Application Programming Interface. Thus the interfaces play an important role in
selecting an EAI tool as they should be such that no/minimum coding will be required while
integrating.

transformation

As data format is not same for all applications, tools are required that let users visually map,
coordinate one application data format with the another application data format and transform
the information as required.

6.16 eai solution evalution

6.16.1 criteria for selection

The EAI solution should have the following functionalities:
1. Workflow Management- facility for designing transaction work flows across applications

2. Seamless Data Transformation- full and simultaneous transformation of application
content among multiple sources and destinations, regardless of application complexity.
3. Intelligent Content Based Routing- powerful, rules based routing of messages, files and
other data objects based on content from any part of the transaction and centralized
management of the routing rules
4. Business Rule Management- graphical environment for definition and management of
business rules to support business process that cross application boundaries
5. Resource Adapters- for seamless technology integration with wide array of data sources
and destinations
6. Functional capabilities and characteristics
7. Flexibility, ease of response to change in integrated applications over time
8. Support for components, including standard component architectures like COM and
CORBA
9. Simplicity or complexity of tools for configuring integration behavior
10. The extensibility provided via traditional programming
11. Development tools provided
12. The other integrators and partners supported

13. The legacy application integration capability and access to mainframe transactions
14. Support provided for heterogeneous messaging infrastructure

6.16.2 eai solution evaluation Methodology

Information Group has come out with an evaluation methodology for EAI solution on the basis
of seven criteria, which can be used to compare different solutions. The point to note here is that
