----------------------------------------------------------- From: AjaySingala[Synergetics] Message 5 in Discussion Kavindra, The "custom" emtity idea is good, but imagine this. U've said that the "custom" entity is smart 'coz it has all get/set and does all database connectivity by itself, right? What if there is a change in the database tomorrow? U want to make changes to your entity? Frankly, if you ask me, the entity by itself should not even know anything about the database. U should use an extra layer here which will do all database interactions. DataSets by themselves are quiet heavy as compared to DataReaders, definitely, but they have many advantages too. Also, doing updates directly from a DataSet is also not a very good idea on an Enterprise Solution. Do it thru the business and data access layers instead. Also, you will not use DataSets all the time. For e.g.; if you are just going to retrieve a list of, let's say "Countries" and show them in a DropDownList, you don't need to use a DataSt there do you? But you may want to use it if you want to show the list in a DataGrid. As far as having an effect on the performance goes, it all depends on the config of the server you see. If we are talking about an Enterprise Solution, I'm sure we're not talking about a 256 MB RAM server here right?
