This way you can have a variety of ways that your object is created and the method is only responsible for the persistance of that object not also it's creation and populating.A couple of problems I see in your approach: // a method higher up the chain void Create Customer Log() void Update Customer Log(string application No) Data_Customer_Log Get Customer Log(string application No) Data_Customer_Log Insert Or Update(Data_Customer_Log record) Data_Customer_Log Insert(Data_Customer_Log record) Data_Customer_Log Update(Data_Customer_Log record) I would probably point out that these methods would probably be in different classes.
