No, it\'s not what I suffer from the lack of (as in sleep). It\'s
Representational State Transfer. It\'s been a buzzword for
a few years now. I\'m just now reading about it, and thought
I would include some highlights here for my own reference.
<a href=\'http://www.xfront.com/REST-Web-Services.html\'>Read
all about it.</a>
From the URL above, REST exhibits the following characteristics:
<ul>
<li>Client-Server: a pull-based interaction style: consuming components pull
representations.</li>
<li>Stateless: each request from client to server must contain all the
information necessary to understand the request, and cannot take advantage
of any stored context on the server.</li>
<li>Cache: to improve network efficiency responses must be capable of being
labeled as cacheable or non-cacheable.</li>
<li>Uniform interface: all resources are accessed with a generic interface
(e.g., HTTP GET, POST, PUT, DELETE).</li>
<li>Named resources - the system is comprised of resources which are named
using a URL.</li>
<li>Interconnected resource representations - the representations of the
resources are interconnected using URLs, thereby enabling a client to
progress from one state to another.</li>
<li>Layered components - intermediaries, such as proxy servers, cache servers,
gateways, etc, can be inserted between clients and resources to support
performance, security, etc.</li>
</ul>
Trying to make my CatalystX::CRUD project more RESTful.
If I needed to explain REST to my wife, I could <a
href=\'http://tomayko.com/articles/2004/12/12/rest-to-my-wife\'>refer her to
this.</a>
The <a
href="http://en.wikipedia.org/wiki/Create%2C_read%C_update_and_delete">Wikipedia
CRUD article</a> maps the RESTful verbs to CRUD and SQL actions like so:
<table cellpadding="3">
<tbody><tr>
<th>Operation</th>
<th>SQL</th>
<th>HTTP</th>
</tr>
<tr>
<td>Create</td>
<td><a title="Insert (SQL)">INSERT</a></td>
<td><a title="HTTP POST">POST</a></td>
</tr>
<tr>
<td>Read (Retrieve)</td>
<td><a title="Select (SQL)">SELECT</a></td>
<td><a title="HTTP GET">GET</a></td>
</tr>
<tr>
<td>Update</td>
<td><a title="Update (SQL)">UPDATE</a></td>
<td><a title="HTTP PUT">PUT</a></td>
</tr>
<tr>
<td>Delete (Destroy)</td>
<td><a title="Delete (SQL)">DELETE</a></td>
<td><a title="HTTP DELETE">DELETE</a></td>
</tr>
</tbody></table>
However, important to note that <B>REST != CRUD</B>.
