<h1>API Reference</h1>
<p>
The CloudBoost API is organized around <a href="http://en.wikipedia.org/wiki/Representational_State_Transfer">REST</a>. Our API is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API errors. We use built-in HTTP features, like HTTP authentication and HTTP verbs, which can be understood by off-the-shelf HTTP clients, and we support <a href="http://en.wikipedia.org/wiki/Cross-origin_resource_sharing">cross-origin resource sharing</a> to allow you to interact securely with our API from a client-side web application / mobile application (though you should remember that you should never expose your secret API master key in any public website's client-side code, Client Key can be exposed). <a href="http://www.json.org/">JSON</a> will be returned in all responses from the API, including errors (though if you're using API bindings / SDK, we will convert the response to the appropriate language-specific object).

<p>
In Cloudboost, you create an app each of which has its own AppID, Java
Client Key and the Master Key that you apply to your web app. You master key is a secret which should not be shared in your client apps. Your account on CloudBoost can accommodate multiple apps.
This is useful even if you have one application, since you can deploy different versions for test and production.

<h3>One-to-Many Relationship</h3>
<p>
If you want to model one-to-many relationship. Then you need to create a new column of type <code> Relation </code> pointed to a table which you want it to be related to and set that column <code> Unique </code> property to false.
</p>

var teacher = new CB.CloudObject("Teacher");
var course = new CB.CloudObject("Course");
//here one teacher be assigned to many courses.
//address column of Student Table is pointed to the Address Table with unique set to true.
course.Set("teacher", address);
student.SaveAsync();

<h3>Many-to-Many Relationship</h3>
<p>
If you want to model many-to-many relationship. Then you have two options<br/>
<ol>
<li><b>#1 - Relation Option</b></li>
<li><b>#2 - List Option</b></li>
</ol>
We will discuss both of these options below. <br/><br/><br/>
<h4>Relation Option</h4>
<p> This option is recommended only if you have huge number of relationships assigned to any one object. </p>
<p> This relationship can be created by creating a third table and having two columns that are relatied to tables you want to have many to many relationships on. </p>
<br/><br/><br/><br/><br/><br/><br/><br/>
<h4>List Option</h4>
<p> This option is recommended only if you have small number of relationships assigned to any one object. </p>
<p> This relationship can be created by creating an array and having related objects pushed to that array and having that array saved in any column of the table. </p>
</p>
</div>
<div class="method-example" id="api-summary-example">
<code class="method-request"><span class="prompt"></span><span class="lang lang-node"><span class="highlight_js javascript">
//Type #1 : Relation Option
var student = new CB.CloudObject("Student");
var course = new CB.CloudObject("Course");
//here one student be into many courses, and vice versa.
var studentCourse = new CB.CloudObject("StudentCourse");
studentCourse.Set("student", student);
studentCourse.Set("teacher", teacher);
await studentCourse.SaveAsync();
// ======================================================
//Type #2 : List Option.
var student = new CB.CloudObject("Student");
//create an array.
var courseList = new ArrayList();
//a new course
var course = new CB.CloudObject("Course");
//add it to the list. You can push any number of objects you need.
courseList.Add(course);
//here one student be into many courses, and vice versa.
student.Set("courses", courseList);
await student.SaveAsync();
