i have developed a client server application with delphi 2007. all business logic and presentation are in client application. i want to move business logic to the server. but i have no idea how to call the business class on the client. and i dont use any orm framework, i use clientdataset on business logic. so i need this clientdataset on the client to connect it to data control. is it possible? is there any article i can read on, cause i'm still not sure the best architecture in delphi for my application(small erp).
