Hi, I would propose DMVC as Rest middle tier. So the scheme would be Client Application -> rest server providing methods to search, update and so on, then MariaDb server. DMVC is powerful and stable ([login to view URL]) and it's a modern and future-proof solution. If you wish to discuss it with me, please be welcome. Augusto Pellisan

Hi, I'm an expert Delphi developer with 20 years experience in Delphi programming. I also have DataSnap experience and can complete this migration of your 2tier Delphi application to 3tier project for you, per your requirements. This will involve : 1) writing the application server, and, 2) re-writing of the clients. I estimate that I can complete and deliver in a week. Good quality work done. Thanks for considering my bid. -Steve
