It is necessary to develop an online booking form for a beauty salon and integrate it into the existing website (landing page). The site is in the development stage (in HTML, CSS, JS). The site does not have its own database (and none is planned), so it is necessary to propose a free solution for storing and managing data that will be easy to administer and stable in operation. Required functionality: loading the list of service categories; loading services according to the selected category; loading the list of masters who perform the selected service; displaying available dates and free times according to the master's work schedule; creating a booking with automatic blocking of the selected time; protection against double booking. Data in the form: name; phone number; service category; service; master; date; time; comment (optional). Administration: There should be the ability to: add and edit service categories; add and edit services; add and edit masters; set the work schedule for each master; manage days off, vacations, and other periods of unavailability; view, edit, and cancel client bookings. Please specify: what solution you propose for data storage; estimated cost; completion time. Design is not important, the main thing is functionality. The person who does the site layout will design it in the required style.
