DataSets with Business Entities and Data Access Layers

[Guest]

For my application, I stick to a Business entity class and a Data Access Layer class design (DAL
For more complex situations I create a custom business entity class which users a DAL class. I also have many other small descriptor tables where I don’t need that level of control

Is it proper to create a class which inherits a dataset. Within this class I perform the steps to make it a typed dataset and set the SQL commands to the DAL class.
