    <p>I have some code that will need to write about 20 bytes of data every 10 seconds. I'm on Windows 7 using python 2.7</p> <p>You guys recommend any 'least strain to the os/hard drive' way to do this?</p> <p>I was thinking about opening and closing the same file very 10 seconds:</p> <pre><code>f = open('log_file.txt', 'w') f.write(information) f.close() </code></pre> <p>Or should I keep it open and just <code>flush()</code> the data and not close it as often?</p> <p>What about <code>sqllite</code>? Will it improve performance and be less intensive than the open and close file operations? (Isn't it just a flat file database so == to text file anyways...?)</p> <p>What about <code>mysql</code> (this uses a local server/process.. not sure the specifics on when/how it saves data to hdd) ?</p> <p>I'm just worried about not frying my hard drive and improving the performance on this logging procedure. I will be receiving new log information about every 10 seconds, and this will be going on 24/7 24 hours a day. Your advice?</p> <p>ie: Think about programs like utorrent that require saving large amounts of data on a constant basis for long periods of time, (my log file is significantly less data that those being written in such "downloader type programs" like utorrent)</p> <pre><code>import random import time def get_data(): letters = 'isn\'t the code obvious' data = '' for i in xrange(20): data += random.choice(letters) return data while True: f = open('log_file.txt', 'w') f.write(get_data()) f.close() time.sleep(10) </code></pre> <p>My CPU starts whining after about 15 seconds... (or is that my hdd? )</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.
