In the first part of this series Fusion Charts and PostgreSQL Part 1: Database Analysis of USDA DB in our November/December 2008 issue, we did some back-seat analysis of a database we had never seen before and formulated some thoughts of things that would be useful to see in a dashboard as well as starting to develop some views to support our Dashboard. In the second part of our Fusion Charts series, we covered creating a Dashboard application in ASP.NET that demonstrated both VB.NET and C# variants using the database we loaded and prepped in Part 1.

In this part three of our series, we shall conclude by demonstrating the same application we did in ASP.NET in PHP.

We are going to create a simple dashboard that has the following features:

A drop-down list to allow the user to pick the kind of chart to display the data in (Bar, column, funnel etc)
A drop-down list that allows the user to pick the metric to explore -- e.g. Cholestrol, Vitamin K, Caffeine etc.
2 charts -- one chart showing the top 5 food groups for our metric and another showing the top 5 foods for our metric

Our final product will look like this:

You can see the app in action - USDA Food Stats and discover some interesting things about the food you eat or were considering eating.

In this part, we start the fun off by building an ASP.NET app in both VB and C#. In the next part of this series, we shall perform the same feat with PHP.

We are going to create a simple dashboard that has the following features:

A drop downlist to allow the user to pick the kind of chart to display the data in (Bar, column, funnel etc)
A drop downlist that allows the user to pick the metric to explore -- e.g. Cholestrol, Vitamin K, Caffeine etc.

Fusion Charts and PostgreSQL Part 1: Database Analysis of USDA DB

In our Product Showcase section of this issue, we introduced Fusion Charts which is a flash-based charting product that makes beautiful flash charts. It comes in both a free and a non-free more bells and whistles version.

In this 3-part series article we shall demonstrate using this with a PostgreSQL database, building a simple dashboard with ASP.NET and PHP. We shall demonstrate both C# and VB.NET both using the PostgreSQL NPGSQL driver.

For this first part we shall simply load the database, do a quick analysis of what we've got to report on and create some views to help us with our PHP and ASP.NET apps that will follow in parts 2 and 3.

We will be testing this on 8.3, but since the database is an old one, it should work just fine on older versions of PostgreSQL. We'll try to refrain from using new features of PostgreSQL.
