<AppML> Case Study - Prototype

This case study demonstrates how to build a complete <AppML> Internet application with the ability to list, edit, and search information for several tables in a database.

Prototype

In this chapter, we will create a prototype model for each table in the database.

Prototypes are a very convenient starting point for developing applications.

Prototype Models

First, create a folder for the prototypes. Name this folder Prototypes.

Then, create a prototype model for each table in the database.

Use SELECT * from each table, and save the models as XML files:

Model: Proto_Customers.xml

<appml>
<datasource>
<database>
<connection>Demo</connection>
<sql>SELECT * FROM Customers</sql>
</database>
</datasource>
</appml>

Model: Proto_Suppliers.xml

<appml>
<datasource>
<database>
<connection>Demo</connection>
<sql>SELECT * FROM Suppliers</sql>
</database>
</datasource>
</appml>

Model: Proto_Products.xml

<appml>
<datasource>
<database>
<connection>Demo</connection>
<sql>SELECT * FROM Products</sql>
</database>
</datasource>
</appml>


Prototype View

Create a prototype view, save it as Demo_Prototype.html, and try it:

View: Demo_Prototype.htm

<h1>Customers</h1>
<div id="List01"></div>

<script src="appml.js.html"></script>
<script>
customers=new AppML("appml.php","Prototypes/Customers");
customers.run("List01");
</script>

Try it »

Now combine everything together

Finally, with a little JavaScript coding, create a simple prototype page for all prototype models:

Demo_Prototype_Views.htm

<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="appml.css.html" />
</head>

<body>
<h1>Demo Applications</h1>

<button onclick='myOpen("Customers")'>Customers</button>
<button onclick='myOpen("Products")'>Products</button>
<button onclick='myOpen("Suppliers")'>Suppliers</button>
<button onclick='myOpen("Shippers")'>Shippers</button>
<button onclick='myOpen("Categories")'>Categories</button>
<button onclick='myOpen("Employees")'>Employees</button>
<button onclick='myOpen("Orders")'>Orders</button>
<button onclick='myOpen("OrderDetails")'>OrderDetails</button>
<br><br>

<div id="Place01"></div>

<script src="appml.js.html"></script>
<script>
function myOpen(pname)
{
var app_obj
app_obj=new AppML("appml.php","Prototypes/" + pname);
app_obj.run("Place01");
}
</script>

</body>
</html>
