    <p><strong>Note:</strong> I have completely changed the original question!</p> <p>I do have several texts, which consists of several words. Words are categorized into difficulty categories from 1 to 6, 1 being the easiest one and 6 the hardest (or from common to least common). However, obviously not all words can be put into these categories, because they are countless words in the english language. </p> <p>Each category has twice as many words as the category before.</p> <ol> <li>Level: 100 words in total (100 new)</li> <li>Level: 200 words in total (100 new)</li> <li>Level: 400 words in total (200 new)</li> <li>Level: 800 words in total (400 new)</li> <li>Level: 1600 words in total (800 new)</li> <li>Level: 3200 words in total (1600 new)</li> </ol> <p>When I use the term level 6 below, I mean <strong>introduced</strong> in level 6. So it is part of the 1600 new words and can't be found in the 1600 words up to level 5.</p> <p>How would I rate the difficulty of an individual text? Compare these texts:</p> <h2>An easy one</h2> <p>would only consist of very basic vocabulary:</p> <pre><code>I drive a car. </code></pre> <p>Let's say these are 4 level 1 words.</p> <h2>A medium one</h2> <pre><code>This old man is cretinous. </code></pre> <p>This is a very basic sentence which only comes with one difficult word. </p> <h2>A hard one</h2> <p>would have some advanced vocabulary in there too:</p> <pre><code>I steer a gas guzzler. </code></pre> <p>So how much more difficult is the second or third of the first one? Let's compare text 1 and text 3. <code>I</code> and <code>a</code> are still level 1 words, <code>gas</code> might be lvl 2, <code>steer</code> is 4 and <code>guzzler</code> is not even in the list. <code>cretinous</code> would be level 6. <strong>How to calculate a difficulty of these texts, now that I've classified the vocabulary?</strong></p> <p>I hope it is more clear what I want to do now.</p>

    1. COI voted to reopen, but I still have doubts what you actually want done. Please consider rewriting the entire question.

    2. COI rewrote it now and hope it makes more sense now. If someone knows about this kind of stuff maybe I can edit appropriate terms into the question, so others can profit as well.

    3. COYOU need to think about what it means to combine words in a sentence. Your problem is one of definition, but that must come from you. Once that definition is available, then the answer will become trivial. Essentially this is a question maybe of linguistics or vaguely of mathematics, but not programming at all at this point.

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.
