    <p>This is an interesting question - not least because I don't believe that there is a single ideal answer as it will depend to some extent on the nature of the "Hotel" and the way in which people are placed in rooms and to a further extent on the scale of the question.</p> <p>At the most basic level you have two ways that you can track occupancy of rooms:</p> <ol> <li>You can have a table with one row per room per day that defines the state of that room on that date (and possibly the related booking if occupied)</li> <li>For each room you maintain a list of "bookings" (which as already suggested will have to include states for when a room is unavailable for maintenance).</li> </ol> <p>The reason that its an interesting question is that these both immediately present you with certain challenges when maintaining the data and searching for occupancy in the case of the former you're holding a lot of data that may not be needed and in the case of the latter finding gaps in the occupancy for new bookings is perhaps more interesting.</p> <p>You then (in both cases) have a futher problem of resource allocation - if your bookings tend to be for two days and you system results in 1 day gaps between bookings you're going to need to re-arrange the occupancy to optimise usage... but then you have to be careful with bookings that need to be explicitly tied to specific rooms.</p> <p>Ideally you would defer assigning a booking to a room for as long as possible (which is why it depends on the hotel - fine for 400 modular rooms rather less so for a dozen unique ones) - so long as there are sufficient rooms of the necessary standard available (which you invert, so long as there are fewer rooms booked than real rooms) during a target period you can take the booking. Of course you've still then got to represent the state of the rooms so this is in addition to the data you've got to manage.</p> <p>All of which is what makes it interesting - there is considerable depth to the problem, you need to have a fairly decent understanding of the specific problem to produce an appropriate solution.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
