Unit 6: Source Integration

these criteria are customer specific i.e., dependent on the customer requirements the importance notes
of each criterion varies. The criteria to be checked are:
1. Adapter/ Connector Fit
2. Tools Productivity/ Quality
3. Runtime Quality/ Scalability
4. Runtime Fit to Purpose

5. Business Process Support
6. Integrator Resources
7. Purchase and Ownership Cost

Adapter/Connector Fit

The extent of provision of pre built or pre configured adapters or connectors in the solution. The
rating is dependent on what packaged applications and legacy environments are required to
be integrated and the quantitative and qualitative assessment of the adapters/ connectors. The
important point to consider in assessment is the impact of the adapter/ connectors available on
the time to market, where a high rating means the amount of pre built connectivity will accelerate
the integration project.
Tools Productivity/ Quality

The productivity of the integration development work is dependent on the quality of tools
provided and thus this criterion’s impact is more in the case where the adapter/ connectors are
not available. If the amount of custom integration work to do is more then this criterion increases
in vitality. This also determines the flexibility and the maintenance cost of the system.

Runtime Quality/ Scalability

Scalability is important as it determines the speed of the system. Quality of service includes the
level of reliability or guarantee of delivery and the level of transaction integrity. Throughput,
latency and efficiency may also be considered for assessment of quality of service.

Runtime Fit to Purpose

There are four main points, which are required in different combinations:
1. Transactional real-time component integration

2. Queued messaging model
3. Publish and subscribe messaging
4. Bulk data movement

Business Process Support

All integration scenarios require business process support. There are two ways by which this can
be taken care of are:
1. Facilities to model business processes and generate or execute an automated version of the
process are include in the integration solution
2. Specific business processes are already pre configured as part of the solution
