It runs on the user’s local machine and references a file that is stored on that machine’s hard drive, thus using a single physical resource to access and process information. For multiple users and small scale applications Two Tier client/server architecture would be better suited than One Tier architecture. Users interact through a GUI (graphical user interface) to communicate with the database server across a network via SQL (structured query language.
