Data Integration

 

Data integration involves synthesizing data placed in different sources and providing users with a unified view of these data.

Say you want to build a report regarding the student attendance and you have to send a letter to each of the students' home. So you will get names, addresses, roll numbers of a student from database. You will have to search the class records to get the attendance of each student. If you want a remarks from each of your teacher on each student then you have to meet every teacher in your class. So here are many sources of data. You have to collect them and combine them in such a way that you can prepare a report. This is a simple example of data integration.

In many fields like commercial, educational, health etc data integration is used in a very large scale.

Many tools help to integrate data. Like Talend Open Studio;.
