High-Level Design (HLD) of Vending Machine
In the High-Level Design section, the general structure and essential additives of the vending machine are outlined.
- How people will use the machine, how money transactions will work, how the products will be managed, and how the machine will talk to other devices ie communication protocols.
- Key selections, including the combination of a coin mechanism, bill acceptor, card reader, and display unit, are made at this stage.
- The HLD acts as a blueprint for the following Low-Level Design (LLD) section, guiding the particular implementation of everything.
