    <p>I am writing a web service and one of the operation in service is <code>getShortURL(String longURL)</code>. In this method I first check whether <code>longURL</code> exists in database, if yes, return it otherwise create a <code>shortURL</code>, insert it in database and return to client.</p> <p>My confusion is how to organize and name my classes. Apart from the web service class, right now I have 3 classes:</p> <ol> <li><code>URLData</code>: It just has URL attributes and getters and setters.</li> <li><code>MongoDB</code>: It connects to database(right now connection attributes are hard-coded in it), inserts in database, and retrieves raw string from database.</li> <li><code>MongoDBUtil</code>: This class has again <code>insert(URLData)</code> method, it calls <code>MongoDB.insert()</code> to insert into database. Also has <code>retrieveURLData</code> which in turn calls <code>MongoDB</code> equivalent method to do the actual job.</li> </ol> <p>Web service method sets <code>URLData</code> setters and calls <code>MongoDBUtil.retrieve</code> or <code>insert</code>.</p> <ol> <li>I am thinking that <code>URLData</code> class should be named <code>URLDataBusinessObject</code> and along with setters and getters it can have insert, update and delete methods.</li> <li><code>MongoDBUtil</code> can be renamed to UrlDAO and it can have different kinds of retrieve methods.</li> <li><code>MongoDB</code> is more kinda Select query class, not sure how to design and name it.</li> </ol> <p>Please advise</p>

    1. COIt's a simple service and best modeled in a simple way imo. There's nothing wrong with your implementation.

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.
