The Entity Data Model and ADO.NET vNext let you deal with tabular data as objects, eliminating much of the effort endemic to older data-retrieval and modification code.

All applications are dependent on data in some form and most developers find themselves writing reams of data access code. Microsoft has been building databinding frameworks for years. Each one promises to solve our databinding woes forever. We're still waiting for the perfect one. In the previous article you were exposed to programmatically controlling data binding mechanisms of WPF. Along with a programmatic interface, WPF also provides a declarative databining interface. This second article will introduce you to using the declarative data binding mechanisms contained in WPF.

Enterprises collect a wide variety of data in the form of text, audio, video, geospatial attributes, web, system and device logs, clickstreams, sensor readings, device outputs, link traversal logs from bots, crawlers, etc. In fact, about 90% of the data in the world has been created in the last few years. As hardware gets cheaper, more people have and use more devices and generate huge volumes of data which needs to be stored and analyzed to create value.

The most popular instrument to access database data for .NET applications is ADO.NET. This set of components contains three main classes those are used to manipulate and store data: DataReader, DataSet and DataAdapter. DataReader is only able to read data and can't work as data source for data-aware components like DataGridView; DataSet provides all interfaces to be a data source but disconnected model considers some restrictions that can become important for some kind of applications, especially for desktop programs that work under multiuser concurrent environment and change database data actively. Below we consider main restrictions and popular ways to solve them; non standard solutions are considered also.

Over the past couple of months I've authored five articles on displaying a grid of data in an ASP.NET MVC application. The first article in the series focused on simply displaying data. This was followed by articles showing how to sort, page, and filter a grid of data. We then examined how to both sort and page a single grid of data. This article looks at how to add the final piece to the puzzle: we'll see how to combine sorting, paging and filtering when displaying data in a single grid.

Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more!

Any application that deals with data needs data validation. Prem walks through aspects of data validation in Microsoft Visual Studio LightSwitch and provides insight into certain details of the underlying framework and design.

When people think of having to store data for their applications, a database such as SQL Server immediately comes to mind. However, XML files are very handy for storing data without the overhead of a database. Using XML files to cache often-used, but seldom changed data such as US state codes, employee types and other validation tables can avoid network roundtrips and speed up your application. In addition, XML files are great for off-line applications where a user needs to add, edit and delete data when they can’t connect to a database.

When migrating data from other sources into a single database used by your app, you'll probably have to employ some matching and de-duplication processes to end up with a useful data store. We'll show you four different matching algorithms and the F# code to implement them.

Find out how to create custom indexes for geographical data that includes latitude and longitude location information so that you can retrieve real-time data faster than ever.

Data integration is the cornerstone of many apps these days, which means you’ll need to add database expert to the many hats you wear. Or maybe not. We’ll show you some handy tools and resources for maximizing data access while minimizing muss and fuss.
