PostGIS ajoute le support d'objets géographique à la base de données PostgreSQL. En effet, PostGIS "spatialise" le serverur PostgreSQL, ce qui permet de l'utiliser comme une base de données SIG.

Maintenu à jour, en fonction de nos disponibilités et des diverses sorties des outils que nous testons, nous vous proposons l'ensemble de nos travaux publiés en langue française.

8 * @class Ext.data.XmlStore
9 * @extends Ext.data.Store
10 * <p>Small helper class to make creating {@link Ext.data.Store}s from XML data easier.
11 * A XmlStore will be automatically configured with a {@link Ext.data.XmlReader}.</p>
12 * <p>A store configuration would be something like:<pre><code>
13var store = new Ext.data.XmlStore({
14    // store configs
15    autoDestroy: true,
16    storeId: 'myStore',
17    url: 'sheldon.xml', // automatically configures a HttpProxy
18    // reader configs
19    record: 'Item', // records will have an "Item" tag
20    idPath: 'ASIN',
21    totalRecords: '@TotalResults'
22    fields: [
23        // set up the fields mapping into the xml doc
24        // The first needs mapping, the others are very basic
25        {name: 'Author', mapping: 'ItemAttributes > Author'},
26        'Title', 'Manufacturer', 'ProductGroup'
27    ]
28});
29 * </code></pre></p>
30 * <p>This store is configured to consume a returned object of the form:<pre><code>
31&#60?xml version="1.0" encoding="UTF-8"?>
32&#60ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2009-05-15">

58 * An object literal of this form could also be used as the {@link #data} config option.</p>
59 * <p><b>Note:</b> Although not listed here, this class accepts all of the configuration options of

61 * @constructor
62 * @param {Object} config
