<h3>LLBLGen::ICommonDBAccess interface</h3>
<p>
LLBLGen will generate in the base class [Class prefix]DBInteractionBase.[cs|vb] file an interface, ICommonDBAccess,
which defines the common methods which are implemented (if possible) by all generated .NET classes,
independent of the table or view layout. The base class implements this interface by virtual / overrideable methods
which throw an NotImplementedException exception when called. If a .NET class implements a method of the
interface, it overrides the method of the base class. This interface is particular useful when you have
a control which should be able to handle more than one data-access tier class, f.e. a control which calls
the SelectAll method of the data-access tier object passed to it, and displays the results. You can, with
this interface, now simply implement the one control and pass any data-access tier object generated by LLBLGen.
See also <a href="codestructure_net.htm">Code structure of the .NET code</a> for descriptions of the methods stated
below.
