I need a small SQL database designed specifically for time-tracking, focused on recording employee hours. On top of that I want a clean, lightweight HTML front-end that lets staff clock-in and clock-out in real time and tags each entry to the customer they are working for. Core needs • Database schema that stores employee profiles, customers, raw punch data and a simple status flag so the system knows who is currently punched in. • Web interface (plain HTML/CSS/JS is fine; PHP or another thin back-end layer if you prefer) with two main screens: one for the actual punch button and one for basic admin review of today’s records. • Basic validation and protection against duplicate punches. • Simple report or query I can run to pull a date-range of hours per employee and per customer. Keep it structured and easy for a non-technical manager to extend later. If you already have a preferred stack—MySQL + PHP, SQLite + Flask, etc.—let me know; I’m flexible as long as setup is straightforward.
