I'm using Visual Studio and Oracle DB.
First of all, sorry for my english..
I want to make a program to enter registers to a DB, these registers can be modified, deleted, etc.. Also you can make querys show all fields, etc.. in a datagrid.
I have done it with sql querys, datareaders, datasets, adapters, etc... but I'm thinking about change the program to improve it and make it easy to be modified. My doubt is, if I want to create classes to do a good application I have to do the querys, create objects, save it in arrays, put it in datagrid. I think this way is too expensive about the memory and time.
How can do it better? What is the best way to do that?
Thanks!
