Homogenise Data Sources

This capability relates to the remote access common capability and shares some of the same principles. The goal is to present data which is actually different as if it is the same. There are two primary ways to do this:

The first involves collecting data into a central database and converting it all to a standard format.

The aim of the second option is to overcome the problems of dealing with a variety of data sources like databases and files by using a component which abstracts the data access in to an interface that makes sense to all of the different data sources. This layer should be at the level that makes sense to the specific application.

Common interface for homogenising data sources

Note that despite their differences both options rely upon the provision of translation components to handle the conversion to the common format and also a common interface to support the homogenised access to the resources for the client.
