We will work through some examples here to help give you a good grounding in the subject. We will also look at a couple of other load techniques that will be very useful in your arsenal—binary load and partial load.

Loading data incrementally

The basic process of an incremental load is to have most of the data stored in QVDs on the server and then connect to the database to just obtain those records that are needed to update the QVDs to be concurrent.
