+<h1>The Usergrid Data Store<a class="headerlink" href="#the-usergrid-data-store" title="Permalink to this headline">¶</a></h1>
+<p>The Usergrid data store is backed by Cassandra, an open source
+distributed DBMS. Cassandra isn’t a relational database system (RDBMS),
+and is sometimes placed in the category of “NoSQL” or “schema-less”
+databases.</p>
+<!-- workaround a Sphinx bug -->
+<div class="admonition note"> <p class="first admonition-title"><p>Note</p>
+</p> <p class="last"><p>Usergrid is not a relational database. Optimizing for performance on a
+non-relational database like Cassandra differs a bit from relational
+databases. For more information, see Optimizing access to your Usergrid
+data store.</p>
+</p> </div><p>Cassandra is specifically designed to support applications that need
+flexibility and high scalability, particularly web and mobile
+applications. Usergrid client applications write and read data formatted
+as JavaScript Object Notation (JSON). (Usergrid provides SDKs through
+which client apps can do much of this work in their native language. For
+more information, see Usergrid SDKs.)</p>
+<p>With Cassandra as the underlying DBMS, apps benefit from:</p>
+<p>Fast writes to the data store. * A distributed architecture that means
+no single point of failure. * Flexibility in data model design. You
+aren&#8217;t constrained by a schema. * Linear scalability.</p>
+<p>If you have experience with relational databases and are unfamiliar with
+&#8220;NoSQL&#8221; databases, the following table might be a helpful start. It maps
+the high-level concepts of an RDBMS’s data model both to Cassandra’s and
+to the Usergrid, which is backed by Cassandra.</p>
+<table class="usergrid-table">
+<tr>
+    <td></td>
+    <td><p>RDBMS</p>
+</td>
+    <td><p>Cassandra</p>
+</td>
+    <td><p>Usergrid</p>
+</td>
+</tr>
+<tr>
+    <td><p>Each tuple is modeled as</p>
+</td>
+    <td><p>A row.</p>
+</td>
+    <td><p>A row.</p>
+</td>
+    <td><p>An entity. Written and retrieved as JSON, an entity contains values for
+all of its properties in the way a row has values for columns.</p>
+</td>
+</tr>
+<tr>
+    <td><p>Each data attribute is modeled as</p>
+</td>
+    <td><p>A column.</p>
+</td>
+    <td><p>A column. Many thousands of columns are supported.</p>
+</td>
+    <td><p>A entity property. An entity has a default set of properties, including
+the entity’s UUID. You can add many more to support your application.</p>
+</td>
+</tr>
+<tr>
+    <td><p>Each group of attributes is modeled as</p>
+</td>
+    <td><p>A table.</p>
+</td>
+    <td><p>A column family. Unlike rows in tables, rows in a column family can have
+differing numbers of columns. Because you’re not using a schema to
+define the model, you can update the column list for a row at any time.</p>
+</td>
+    <td><p>An entity collection. As with its underlying Cassandra column family, a
+collection can have entities with differing numbers of properties. In
+other words, just because one entity has an authorId property doesn’t
+mean that other entities in its collection need to.</p>
+</td>
+</tr>
+</table><p>The following examples from a product database provide simple
+illustrations of these differences.</p>
+<p>An RDBMS table has a schema-defined set of columns per row.</p>
+<img alt="../_images/rdbms.png" src="../_images/rdbms.png" />
+<p>A Cassandra column family includes rows that can have differing column
+sets.</p>
+<img alt="../_images/cassandra.png" src="../_images/cassandra.png" />
+<p>In the JSON from the Usergrid application, the products are represented
+as entities. Note that each entity in the entities array below has a
+slightly different set of properties, like the columns in a Cassandra
+column family.</p>

+<h2>Creating Custom Data Entities<a class="headerlink" href="#creating-custom-data-entities" title="Permalink to this headline">¶</a></h2>
+<p>This article describes how to create custom data entities and entity
+properties. Entity types correspond to the name of collection to which
+they are posted. For example, if you create a new custom &#8220;dog&#8221; entity, a
+&#8220;dogs&#8221; collection will be created if one did not already exist. If a
+&#8220;dogs&#8221; collection already exists, the new &#8220;dog&#8221; entity will be saved in
+it. All user-defined properties are indexed, and strings that contain
+multiple words are keyword-indexed.</p>
+<p>The methods cited in this article should be used to create custom data
+entities. If you are using one of the Usergrid SDKs, use one of the
+entity type-specific SDK methods to create default data entities.</p>
+<p><strong>Note</strong>: Although not shown in the API examples below, you need to
+provide a valid access token with each API call. See Authenticating
+users and application clients for details.</p>
+<div class="section" id="creating-a-custom-entity">
+<h3>Creating a custom entity<a class="headerlink" href="#creating-a-custom-entity" title="Permalink to this headline">¶</a></h3>
+<p>When a new entity is created, Usergrid will automatically create a
+corresponding collection if one does not already exist. The collection
+will automatically be named with the plural form of the entity type. For
+example, creating a custom entity of type &#8216;item&#8217; will automatically
+create a collection named &#8216;items&#8217; in which all future &#8216;item&#8217; entities
+will be saved.</p>
