Django 1.2 E-commerce: Data Integration

by Jesse Legg | May 2010 | e-Commerce Open Source Web Development

The needs of every e-commerce application can vary widely when it comes to reports, metrics, and data exports. Some businesses will want to capture detailed profiles of their customers and what they are purchasing in order to optimize promotions and marketing activities for their particular needs. Others will be interested in making data available internally, to provide the boss updates on how many jars of cranberry preserves sold in December last year versus this year.

In this article by Jesse Legg, author of Django 1.2 e-commerce, we will discuss a toolbox of Python libraries and Django applications to assist with whatever reporting needs that may arise. These topics include:

  • Serializing and exposing data
  • Tracking and improving search engine rank using sitemaps
  • Exporting information via RSS and Atom feeds
  • Salesforce integration

Generating charts and graph-based reports will be covered seperately in another article.

Distributed transaction using WCF

by Mike Liu | June 2010 | Enterprise Articles Microsoft

WCF is the acronym for Windows Communication Foundation. It is Microsoft's latest technology that enables applications in a distributed environment to communicate with each other.

In this article series, we will first verify that the LINQNorthwind WCF service does not support distributed transaction processing. We will then explain how to enhance this WCF service to support distributed transaction processing and how to configure all related computers to enable distributed transaction support. To demonstrate this, we will propagate a transaction from the client to the WCF service and verify that all sequential calls to the WCF service are within one single distributed transaction. We will also explain the multiple database support of the WCF service and discuss how to configure MSDTC and the firewall for the distributed WCF service.

In this article by Mike Liu, author of  WCF 4.0 Multi-tier Services Development with LINQ to Entities We will cover the following topics in this article:

  • Creating the solution files
  • Testing the transaction behavior of the DistNorthwind WCF service
  • Enabling transaction flow in the service bindings
  • Modifying the service operation contract to allow transaction flow
  • Modifying the service operation implementation to require a transaction scope
  • Configuring the Distributed Transaction Coordinator for the distributed WCF service

Displaying SQL Server Data using a Linq Data Source

by Dr. Jay Krishnaswamy | May 2009 | Microsoft

Linq to SQL is an object relational model that you can leverage in Visual Studio 2008. Your connection to SQL Server 2008 database is through a new control in Visual Studio 2008, the LinqDataSource control. This control needs a data context. The data context is provided by the Linq to SQL classes, a class generator that maps SQL server objects to the model. The class files generated support CRUD operations.

In this article by Dr. Jay Krishnaswamy, we will be adding a LinqDataSource control in Visual Studio 2008 to a ASP.NET website and configuring it by providing a data context. The data context will created using the Object Relational Designer(O/R Designer) in Visual Studio. The Linq data source is then bound to the Gridview in the Visual Studio designer.

Displaying MySQL data on an ASP.NET Web Page

by Dr. Jayram Krishnaswamy | August 2009 | Open Source PHP

Web enabling business data is one of the key devices used to advertise and market products. This can be done with various technologies such as VB, ASP, JSP, ASP.Net and many others.

The table used in this tutorial was the one described in the first article in this series on Exporting data from MS Access 2003 to MySQL.

This article by Dr. Jay Krishnaswamy explains how to populate a GridView on an ASP.NET web page by data retrieved from a MySQL Server. MySQL.Data.MySqlClient is a connector (provider) provided by MySQL which you can use with the .NET Framework applications whose details may be reviewed here. MySQL is well integrated with Visual Studio (MySQL Visual Studio Tools: MySQL.VisualStudio.dll).

Displaying Data with Grids in Ext JS

by Colin Ramsay Shea Frederick Steve 'Cutter' Blades | October 2010 | AJAX Open Source

The grid is, without doubt, one of the most widely-used components of Ext JS. We all have data, and this needs to be presented to the end user in an easy-to-understand manner. The spreadsheet (a.k.a. grid) is the perfect way to do this—the concept has been around for quite a while because it works. Ext JS takes that concept and makes it flexible and downright amazing!

In this article by Shea Frederick, Colin Ramsay, Steve 'Cutter' Blades, and Nigel White, authors of the book Learning Ext JS 3.2, we will be:

  • Using a GridPanel to display structured data in a user-friendly manner
  • Reading data from the server (which provides the data from a database) to display in the grid
