    <p>I would suggest a slightly different test, it is not a simple mathematical algorithms and functions. There are plenty of odd-looking tests whose results always contains all reviews. You launch the application, it works for a while, and then gives you the result in standard scores. The more points more (or less), it is considered that the device better. But that the comparison results mean in real life, is not always clear. And not all. Regard to mathematics, the first thing that comes to mind is a massive amount of counting decimal places and the task to count the number "pi"</p> <p>OK. No problem, we will do it:</p> <p>Here's a test number one - "<strong>The Number Pi</strong>" - how long it takes your phone to calculate the ten million digits of Pi (3.14) (if someone said this phrase a hundred years ago, exactly would be immediately went to a psychiatric hospital)</p> <p>When you feel that the phone is slow. You turn / twist interface. But how to measure it - it is unclear. Angry Birds run on different devices at different times - perhaps test "Angry Birds"</p> <p>We think further - get a couple more tests, "heavy book" and "a large page."</p> <p>algorithm of calculation:</p> <ol> <li>Test "of Pi"</li> </ol> <p>Take the Speed Pi. Count ten million marks by using a slow algorithm "Abraham Sharp Series. Repeat measurements several times, take the average.</p> <ol> <li>Test "Angry Birds"</li> </ol> <p>Take the very first Angry Birds (not required, but these versions are not the most optimized) </p> <p>Measure the time from launch to the first sounds of music. Exit. Immediately run over and over again. Repeat several times and take the average.</p> <ol> <li>Test "Large Page"</li> </ol> <p>Measure the load time of heavy site pages. You can do it with your favorite browser :)</p> <p>You can use <a href="http://helpix.ru/opinion/201201/43896-huawei_u8860_honor.html" rel="nofollow">This link</a> (sorry for the Cyrillic)</p> <p>This page is maintained by using "computers browser" along with pictures. Total turns out 6.5 Mb and 99 files (I'm still on this page in its stored version of a small sound file) </p> <p>All 99 files upload to the phone. Turn off Wi-Fi and mobile Internet (this is important!)</p> <p>Page opens with your browser. Click the "back" button. And now click "Forward" and measure the time the page is fully loaded. And so a few times. Back-forward, backward-forward. As usual, we take the average.</p> <p><em>All results are given in seconds.</em></p> <p><em>During testing all devices that support microSD cards, was one and the same card-Transcend 16 Gb, class 10. And all data on it.</em></p> <p>Well, the actual results of the tests for some devices <a href="https://docs.google.com/spreadsheet/ccc?key=0Av3LioPm9LYVdHRmNzJWVFJoY25yaXhDRnR1SzhqV3c&amp;usp=sharing" rel="nofollow">TEST RESULT</a></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.
