The ADO.NET Entity Framework is almost here! First introduced as ADO.NET vNext in 2006, the framework is now ready for prime time with the upcoming release of Visual Studio® 2008 SP1. After a couple of unsuccessful attempts at similar products over the years, Microsoft released two technologies with Visual Studio 2008 that fit, in part, into the Object Relational Mapping (ORM) space: LINQ to SQL and the ADO.NET Entity Framework. With the adoption of these technologies in the marketplace, develop...

ADO.NET provides a rich programming interface that allows developers to interact with rows through the DataTable, DataRowCollection, and the DataRow objects. Because I receive many questions regarding DataRow objects in ADO.NET, I have combined several of them and will present the answers in this month's installment of Data Points. I'll explore how you can manipulate data using the DataRow and focus on importing loading, traversing, locating, and examining data in ADO.NET and C#....

X ML has taken the development community by storm. But until the introduction of ADO.NET, the basic tenets of XML have not been fully implemented by a data access toolset. Because ADO.NET has XML at its core, it can handle full-feature XML data structures as well as relational data structures. This wasn't always the case. ADO 2.x required the use of either the hierarchical recordset structure (which was very slow and not sufficiently intuitive) or the standard Recordset object with a matrix of c...

In this month's column I will focus on some data management techniques commonly required in enterprise applications. These include saving parent-child data in a multitier application using ADO.NET, ADO.NET transactions, merge techniques, and a number of other ADO.NET features. I'll also discuss the best process for incorporating consistent and informative exception-handling techniques and debugging strategies into your multitier app....

With the release of Microsoft® .NET just around the corner, developers are gearing up to take advantage ot the many features, increased interoperability, and better data integration that the new framework promotes. While COM and Visual Basic® 6.0 are still widely used and will likely live on for years to come, I've met many developers who are anxious to get moving with the .NET components. Some of the questions I am asked most often regarding .NET are how developing with ActiveX Data Objects (AD...

Last month (November 2001) I concluded that in ASP.NET, caching is the key to performance if you want to exploit Web controls and maintain optimal server response times. Caching relates directly to applications that can work disconnected from the data source. Not all applications can afford this. Applications that work in a highly concurrent environment that need to detect incoming changes to data can't be adapted to work disconnected. However, there are scenarios where you have a large block of...

The vast majority of applications built today in-volve data manipulation in some way—whether it be retrieval, storage, change, translation, verification, or transportation. For an application to be scalable and allow other apps to interact with it, the app will need a common mechanism to pass the data around. Ideally, the vehicle that transports the data should contain the base data, any related data and metadata, and should be able to track changes to the data. Here's where the ADO.NET DataSet ...

I recently discovered some features of ActiveX® Data Objects (ADO) 2.5 that make it easier to use XML and your data source in your Web applications. I was working on Internet and intranet apps that run on Windows® 2000, so I could take advantage of ADO 2.5 to make data manipulation easier. Let's take a look at the benefits of ADO 2.5 that I found in my research and how I dealt with some of the problems you may encounter....

Implementing data access functionality is a core activity of most developers working with the .NET Framework, and the data access layers they build are an essential part of their applications. This article outlines five ideas to consider when building a data access layer with Visual Studio .NET and the .NET Framework. The tips include taking advantage of object-oriented techniques and the .NET Framework infrastructure by using base classes, making classes easily inheritable by following guidelin...

One of the most fundamental differences between ADO.NET and classic ADO is how the data is represented. In ADO.NET it's represented in related DataTable objects, whereas classic ADO represents data in Recordset objects. Using classic ADO, the typical app retrieves a single rowset and stores it in a single Recordset object. When using DataTable objects in ADO.NET, you can store several rowsets in several DataTable objects, all related to one another and contained within a single DataSet....

In recent years ADO has taken the lead as the preferred method for implementing data access in Windows®-based applications. Huge numbers of ADO applications are in use today and many developers are well versed in ADO development. With the introduction of the Microsoft® .NET Framework came ADO.NET—the evolution of ADO. While there are similarities between ADO and ADO.NET, the way they operate and their foundations are quite different. To help you make a smooth transition to ADO.NET, I'm going to ...
