How to integrate different systems

The data that comes from various systems into an application should be handled in a way that we have to do minimum of the work for integration with different systems that provide data.

  1. Defined a common interface.
  2. All the systems that provide data have to provide a database that follows the interface specification.
  3. Application should be able to handle this data.

So this makes it quite easy to get data from other systems.

This may not always be possible but is a way to avoid to many implementations in an application.
