The "
Making the Business Object Aware of the New Table" version assumes that the business object is based on Guid primary keys. This is generally going to be the case, although in exceptional cases, integers or strings could be used. When using these types, the overall concept remains very similar. All the methods overridden above still need to be overridden. However, this time, the overloads with the appropriate first parameters types need to be overridden, rather than the Guid version. Here is a C# example for a business object that is based on integer types:
As you can see, the code is almost identical, with the exception of the first parameter type of each method. Business objects that use string keys instead have to declare the first parameter as a string.
