Data Integration

The Data mining architecture has various phases through which the gathered or stored data crosses before it becomes a valid and powerful data which is help for extracting the knowledge for the improvement. Data Integration is the next phase to the data gathering which includes the summation of data’s from various related databases under a common repository. It is done for easy access and also for saving the memory space for storing of data’s in future too. These data are being cleaned and thus they are free from noise, missing values etc. Even though they are cleaned, we perform further cleaning here too. This is mainly to make the integrated data more secure.
