/**
 * Defines the contract for implementations that specify an operation that needs to be executed on the database, given
 * a DbUnit dataset. Implementations typically call an implementation of DbUnit's DatabaseOperation class.
 * Implementations must have an empty constructor so that an instance can be created using reflection.
 * 
 * The concrete implementation class that is used can be configured using the annotation attribute
 * {@link org.unitils.dbunit.annotation.DataSet#loadStrategy()}. A default can be specified using the property
 * DbUnitModule.DataSet.loadStrategy.default.
 * 
 * This wrapper mechanism makes it very easy to use custom DbUnit DatabaseOperation composite object
 * structures, without sacrificing the powerfulness of Unitils' configuration system.
