    <p>This is the subject matter of a whole library of books, so I will just give an introduction here :-) You can basically start scripts directly and then have multiple options to do this in a way that they keep running in the background.</p> <p>If you have certain functionality that needs to run on regular moments, you would do this by scheduling it:</p> <ul> <li>Windows: Windows Scheduler or specific scheduling tools</li> <li>Linux: <a href="https://en.wikipedia.org/wiki/Cron%20Cron" rel="nofollow noreferrer">Cron</a></li> </ul> <p>If your problem is that you want to start a script without it closing on you while SSH'ing into Linux, you want to look into the "screen" or "tmux" tools.</p> <p>If you want to have it started automatically this could be done by using the "At Startup" as you point out and Linux has similar functionalities, but the preferred and more robust way would be to set up a service that is better integrated with the OS.</p> <ul> <li>Windows: <a href="https://stackoverflow.com/questions/32404/can-i-run-a-python-script-as-a-service-in-windows-how">Windows Service</a></li> <li>Linux: <a href="https://en.wikipedia.org/wiki/Daemon_%28computing%29%20Daemon" rel="nofollow noreferrer">Daemon</a></li> </ul> <p>Even more capabilities can be yielded by using an application server such a Django</p> <p>Tomcat (see comment) is an option, but definitely not the standard one; you'll have a hard time finding support both from Tomcat people running Python or Python people running their stuff on Tomcat. That being said, I imagine you could enable CGI and have it run a Python command with your script.</p> <p>Yet, instead of just starting a Python script I would strongly encourage you to have a look at different Python options that are probably available for your specific use case. From lightweight web solutions like <a href="http://flask.pocoo.org/" rel="nofollow noreferrer">Flask</a> over a versatile networking engine like <a href="http://twistedmatrix.com/trac/" rel="nofollow noreferrer">Twisted</a> to a full blown web framework like <a href="https://www.djangoproject.com/" rel="nofollow noreferrer">Django</a>.</p> <p>They all have rather well-thought-out deployment solutions available. Look up <a href="http://webpython.codepoint.net/wsgi_tutorial" rel="nofollow noreferrer">WSGI</a> for more background.</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.
