<p>You can take an advantage of the <b>Information Blocks</b> module to display and manage structured information.</p>
 
<p>You can use information blocks to create:</p>
 
<ul> 
  <li>news sections;</li>
 
  <li>articles; 	</li>
 
  <li>product catalogs; 	</li>
 
  <li>photo galleries;</li>
 
  <li>job lists; 	</li>
 
  <li>billboards; 	</li>
 
  <li>link catalogs; 	</li>
 
  <li>FAQ pools  etc. 	</li>
  </ul>
 
<p>Information blocks offer a convenient way to store frequently updated information. Information blocks make adding and updating information easier owing to structured storage as well as data import and export functions.</p>
 
<p>The following notions form the information blocks infrastructure:</p>
 
<ul> 
  <li>information block types;</li>
 
  <li>information blocks; 	</li>
 
  <li>information block sections;</li>
 
  <li>information block elements. </li>
 </ul>
 
<p><b>Information</b><b> block types </b>(e.g. Catalog, Disctionary, Jobs, News, Photos) are used to group information blocks. Information blocks of the same type are usually devoted to a common subject and have similar structure. For example, information blocks <b>Company News</b>, <b>New Arrivals </b>and <b>Partner News </b>can be of a single type: <b>News</b>.</p>
 
<p><b>Information</b><b> blocks</b> represent structures of heterogeneous information. For example: blocks &laquo;Phones&raquo;, &laquo;Partner News&raquo;, &laquo;Product News&raquo; etc. Depending on parameters of the type to which the information block belongs, it can contain sections and subsections (i.e. it can have tree structure).</p>
 
<p><b>Sections</b> are logical units used to group elements inside an information block. Sections can form the hierarchical information storage structure. Names of information block sections (<b>Group</b>, <b>Section</b>, <b>Type</b> etc.) are defined when creating the information block type to which they refer.</p>
 
<p><b>Information</b><b> block elements</b> contain stored information. For example: news, product, photo, vacancy, dictionary entry etc.</p>

<p>The example that you can find in the <b>Content</b> section (<b>/content/</b>) uses the following information block types:</p>
 
<ul>
  <li>News; 	</li>

  <li>Bookshop; 	</li>

  <li>Photo Gallery; 	</li>

  <li>Media;</li>

  <li>Services.
    <br />
  </li>
</ul>

<p>The <b>News</b> section (<i>/content/news/</i>) displays the contents of the <b>e-Store News</b> information block using the <b>News </b> <b>line</b> <b> </b>composite component.</p>
 
<p>The <b><a title="Demo Bookstore" href="http://localhost:1108/e-store/books/"></a>Demo Bookstore</b> section (<i>/content/catalog/</i>) elements of the <span id="ctl00_AdminMenu1_LabelMenuContainer"></span><a title="" href="../bitrix/admin/IBlockListAdmin.aspx?type_id=20&amp;iblock_id=25&amp;filter_sectionid=0"></a><b>Books</b> information block.</p>

<p>The <b>Photo Gallery</b> section contains two subsections: <span id="ctl00_AdminMenu1_LabelMenuContainer"></span> <b>Holiday</b>  and <strong>My  album</strong>. The <b>Photo Gallery</b> elements are displayed using the<b> Photo gallery</b> <b> </b>composite component.</p>
  
<p>The <b>Classifieds</b> page displays the contents of the <b>Bulletin Board</b>   information block using the <b>Catalog</b> composite component. </p>

<p>The <b>Media Gallery</b> section renders media items from a selected information block using the <b>Media Gallery</b> component.</p>

<p>The <b>URL Processing</b> section illustrates the SEF (search engine friendly URL's) features.</p>

<p>The <b>AJAX</b> section does just what it speaks of: sows how a component can function in AJAX mode.</p>
