The application (Business Layer) should not care about the techniques behind the persistance
layer at all! This means, when the database design changes in the future,only the persistance layer has to be updated.

Example:
View from persistance layer to database:

    Select xx, yy from table zz, etc

View from Business Layer to Persiswtance Layer:

     saveObject();
     retrieveObject();
     deleteObject();

And that's all! The business layer doe3s not need to know anything else about SQL. These tree commands are enough.
