    <p>I have a simple subject reservation here made up of html, css, javascript, and jquery. I would like to ask if is it possible that if for example there are 5 remaining slots, if i clicked the "Reserve" button it will decrease into 4. So, there are 4 remaining slots already. If I close the browser or restart the computer and when I will run again the program, the remaining slots will remain 4. Is it possible?</p> <p>This is my code:</p> <pre><code>&lt;script type="text/javascript"&gt; var availableSlot1 = 5; var reduceSlot1 = function(valueToDeduct1){ availableSlot1 = availableSlot1 - valueToDeduct1;

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.
