Peter,

>I have another question about how Mere Mortal handle the changes to the database tables. Assume that I have business object created from a set of table SampleTbl. Later I updated the same table with several new columns or delete an existing column, how does Mere Mortal handle such changes.

The Business Layer Generator allows you to pick and choose which objects you want to generate. So, for example, you can specify that you only want to generate the Entity object which will not overwrite any business logic or rule logic in existing classes. For details, check out the MM .NET Dev Guide topic "Mere Mortals .NET Business Objects | Using the MM .NET Business Layer Generator | Step 2: Specifying Code Generation Settings | Specifying Which Classes to Generate".
