Data appending involves transferring data from one database to another.

The databases are linked through a common field such as name or address.

When the common fields are linked the desired data fields are transferred.

Frequent data appends include telephone numbers and email addresses.

Data appending is also the foundation for customer and sales leads profiles.

First we identify key variables that will improve target marketing accuracy. 

Then we identify high quality data sources for each key targeting variable.

Finally we transfer the desired data through the common database field.
