In 2018 Iran, Telegram was not an app — it was where commerce happened. So when the Database Laboratory course asked for a database with a real interface, the honest interface was a chat: ask a bot what a gadget costs, get the answer from the data.
What I built
- The database itself — designed and implemented in SQL Server for a catalogue of digital gadgets and their prices
- A Java bridge to the Telegram Bot API: a message comes in, becomes a query, and the price comes back in the chat
Small project, honest lesson: the interface people already live in beats the one you wish they would open.
