Custom Business Object creation and usage (with iBatis posssible)?

Hi,

I am new to iBatis.Net (and n-tier architecture in general) but would like to try, pls correct me if my understanding is wrong. Just wonder:

1. Since iBatis is an sql mapper, is it I still have to write the business objects myself? If I have 50 tables in my app (assume each BO mapped to each table) and each table has about 70 fields, then I have to write all the classes and properties myself?

2. How the business object classes should be look like? If let say the business objects is used throughout my application, how to have things like deleted/original value, sorting, field max length, etc..? How will it work when bound to a datagrid?

Thanks.
