In this article by Matthew Nohr and Isaac Robinovitch, we will learn how to create an application using Appfog. The AppFog console is a very useful tool, but you can also create applications completely from the command line. In this article, we will create a simple application directly from the command line and publish it as a new application to AppFog.Read Creating an Application from Scratch in full
In this article by Ajit Kumar, author of Sencha MVC Architecture, we will take a step-by-step approach to create a functional application in ExtJS using the MVC architecture and the framework classes related to it. For the sake of completeness and illustration of the concepts, we will be taking up an application requirement and implementing it in ExtJS.
As a requirement, we will be creating an application, which would:
Show the list of departments and the users
Show the list of users for a selected department
Allow the user to edit user information
Refresh the users list to get all the users of all the departments
In web application development, gauges can be useful for showing complicated or dynamic data in a visual or intuitive way. In this article by Sandro Paganotti, author of Designing Next Generation Web Projects with CSS3, we'll learn how to create a fully customizable animated gauge that can respond to real-time changes. We'll also discuss techniques to port this type of widget for support in older web browsers. We'll start by learning about a cool SASS enhancement called Compass; this is another way to deal with CSS3 experimental prefixes. The following is the list of the topics we'll discuss:
A basic gauge structure
Moving the arrow
Animating the arrow
Dealing with older browsers
As noted in Part 1, OLAP presents Business Intelligence via what is known as a CUBE. A Cube has many dimensions and it provides a faster method to access the intelligence compared to the structured querying where the overhead of 'Joins' makes it inefficient. Taking the example of a 'Sales' Cube having everything related to sales we can identify the dimensions as the Sales Outlet, The Customers , the Products and the time period over which sales are being audited or looked into. We also notice that there are certain measures that we are interested related to these 'dimensions' like 'Store Sales', 'Cost of Products, 'number of units sold' etc. The Analysis Services analyzes these intricate relationship that exist in a cube. In this part we will see the process of creating a Cube in VS 2008.Read Creating an Analysis Services Cube with Visual Studio 2008 - Part 2 in full
A cube in the context of Business Intelligence is a multidimensional representation of business facts that can be accessed quickly to provide specific information. (This can be accomplished by properly written queries in a relational database, but the overhead involved in processing the query, which may involve a large number of 'joins', is simply not efficient). While a relational model is more suited to OLTP, a different model is necessary for OLAP. Whereas highly normalized tables are a norm for OLTP, the model for OLAP does not require normalization. The SQL Server Analysis Services that supersedes the earlier versions is specifically meant for analyzing data in the archives or in OLTP databases to be retrieved and burnished to provide the 'Intelligence' by mining for facts hidden in the data. This two part article by Dr. Jayaram Krishnaswamy describes how a Cube is designed using Visual Studio 2008 and how it may be browsed on the Analysis Server. In Part 1, the necessary items for creating the Cube, namely the Data Source and Data Source Views are described.Read Creating an Analysis Services Cube with Visual Studio 2008 - Part 1 in full
The administration interface is a universal feature needed in any web application that stores and manages data. For this reason, Django comes with a fully fledged administration interface ready to be used. This administration interface is considered one of the coolest features in Django because it's easy to use, and yet is powerful and flexible. This article is based on the updated version- Django 1.0. The previous article on Creating an Administration Interface was on the older version of Django.
In this article by Ayman Hourieh, you will learn how to:
- Activate the administration interface
- Use the administration interface to manage content
We need an administration interface to manage the content that users post to our website. In fact, the administration interface is a universal feature needed in any web application that stores and manages data. For this reason, Django comes with a fully-fledged administration interface ready to be used. This administration interface is considered one of the coolest features in Django because it's easy to use, yet powerful and flexible.
In this article by Ayman Hourieh, you will learn about:
- Activating the administration interface
- Using the administration interface to manage content
- Customizing the administration interface
- Assigning permissions to users and groups
Tables got a bad review in accessibility circles, because they used to create complex visual layouts. This was due to the limitations in the support for presentational specifications like CSS and using tables for layout was a hack—that worked in the real world—when you wanted to position something in a precise part of the web page.
Tables were designed to present data of all shapes and sizes, and that is really what they should be used for.
This article by Joshue O Connor, shows how to build a simple table using Joomla! and the features contained within the WYSIWYG editors that can make the table more accessible.Read Creating Accessible Tables in Joomla! in full

This article by Jayaram Krishnaswamy describes how you may connect to SQL Server 2008 and display the retrieved data in a GridView Control on a web page. Trying to establish a connection to the SQL Server 2008 is not possible in Visual Studio 2008 as you will see soon in the tutorial. One way to get around this, as shown in this tutorial, is to create an ODBC connection to the SQL Server and then using the ODBC connection to retrieve the data.
Visual Studio 2008 Version: 9.0.21022.8 RTM, Microsoft Windows XP Professional Media Center Edition, and SQL Server 'Katmai' were used for this tutorial.Read Creating a Web Page for Displaying Data from SQL Server 2008 in full

MySQL Query Browser, one of the open source MySQL GUI tools from MySQL AB, is used for building MySQL database queries visually. In MySQL Query Browser, you build database queries using just your mouse—click, drag and drop!
When you’re creating a query for non-technical users and you don’t want them to see the complexity of the query, you can create a view from the query. Your users can then use the view as a table; for example, they can double-click the view, which will effectively execute its complex query behind the scene.
In MySQL Query Browser, you have two ways to create a view, which Djoni Darmawikarta will demonstrate in this article:
- From an existing query
- Writing from scratch manually
