Actually, my case is that I have to access the database that is for the AV Devices, with tpye, brand name and model code, and it will not be changed i.e. static. So, there is no need for the user to insert, update or delete the items in database. But what I have to is to get the plenty of items that I need to store in my main program and then to show it. So, is MySQL enough? Or is it better if I use PostgreSQL? Thank you very much again.
