Data Integration

Have You ever heard about Data Integration?
Do You know what exactly it is?

Data Integration - it is almost as simple as it sounds and it is pretty much intangible goal which software industry is still running for. In this article I will try to explain why data integration is so huge bite for this companies.

Data integration is like big tree where every branch connected and cooperating with the other. All the data living in this “branch” affords to the users unification view of this data. The process of data integration occurring in every part of our live. For example: when two similar company have to merge their databases or at education to merge different results. However, in our contention world the ITC infrastructure played major role in a learning environment which can drawn in the right students, sponsoring and research project. The most important think is the role to data integration. It means that two system can be integrate when:
Both look the same;
Act seems to be the same;
and both of this system produce and consume the same data.
In sum, data integration is the ability to control, make, share and consume the same data.

Example

Some web application have information about the cities such a weather, demographics, cinemas, hotels, tourism, etc. Typically, the information have to be in one type of database with a single schema. But it is not as simple as seems to be. Single enterprise would find the information which can be difficult to collect. Even if resources gather volumes of information about weather or tourism, it would probable duplicate the data.

The originators of this idea try to develop the best model of virtual schema that the users want the most. This wrapper escorted to resources or application to improve on compatibility of the crime database weather websites. This adapters for each data source transform the query results into a straight form. Finally, the database connect the performance to show unified view and answer for the users question.
