Body
You can start off with connecting a MySQL DB because setting up MySQL is pretty simple. Try <a href="http://www.karlkraft.com/index.php/2010/06/02/mysql-and-objective-c/" rel="nofollow noreferrer">this</a>. This seems like a simliar question. What I would suggest you is that learn basics of PHP, connecting to MySQL via PHP and read all your database contents and echo it as a JSON, your mobile client can use a <a href="https://stackoverflow.com/questions/4025349/is-there-an-3rd-party-library-for-parsing-json-on-the-iphone/4025379#4025379">JSON parser</a> that would parse and give you valid information that was echoed from your PHP script. For setting up Apache, MySQL , PHP you can go with <a href="http://www.mamp.info/en/index.html" rel="nofollow noreferrer"> MAMP for mac</a> or if windows try <a href="http://www.wampserver.com/en/" rel="nofollow noreferrer">WAMP server</a> I have done a small service with MAMP, just echoing a JSON to a client <pre><code><?php // Returns: ["Apple","Banana","Pear"] echo json_encode(array(fruit1=>"Apple", fruit2=>"Banana", fruit3=>"Pear",fruit4=>"JackFruit",fruit5=>"Guava",fruit6=>"Pomogrenate")); ?> </code></pre> So instead of hardcoded values you should fetch results from your MySQL db and echo it. <pre><code><?php $con=mysqli_connect("localhost or host name","username","password","databasename"); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } $result = mysqli_query($con,"SELECT * FROM Persons"); while($row = mysqli_fetch_array($result)) { echo json_encode(array(firstname=>$row['FirstName'],lastname=>$row['LastName'])); echo " "; } mysqli_close($con); ?> </code></pre>

Guidance

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.
