ADO.NET v2.0 will finally provide a built-in object-relational mapper called ObjectSpaces. What is an O/R mapper? Its a framework that lets you totally avoid SQL and stored procs! Note that I'm not talking about generating the SQL or stored procs, like many tools do now; no, I mean totally avoid it and have the framework transparently do all the CRUD for you. That may sound like an impossible dream, if you've never looked into these types of tools, but its very doable and its been rather commonp...

The article shows a simple comparison between Linq to SQL and ADO.NET for the excution time of Selecting data from SQL Server Database. LINQ to SQL provides a runtime infrastructure for managing relational data as objects without losing the ability to query. Your application is free to manipulate the objects while LINQ to SQL stays in the background tracking your changes automatically. Linq to SQL gives you your database, tables, columns as objects that you can use them directly in your C# or VB...

When your goal is a scalable and efficient enterprise solution, you need to develop an efficient data-access strategy. You can't just do some testing on your production machines and rely on the results. While an application can exhibit excellent response times when serving a few users, performance problems can surface when the load increases. So when I am asked to perform architectural and code reviews, there are several coding patterns I look for. In this column, I will share some of them as th...

The Journey Toward ADO.NET

The journey to ADO.NET started with Microsoft's first offering for accessing data viz. DAO (Data access objects) which was designed basically keeping in mind the need of VB programmers to access Microsoft's Access database (also known as the Jet Engine). This technology could be used for accessing the SQL Server and Oracle databases too but this proved to be extremely slow and painful. The process was slow because even though DAO uses ODBC it is designed specifically to talk to Jet. Jet translat...

The advent of ASP back in late 1996 when ADO 1.0 was released represented a new way of dynamically retrieving data from a database. Though ADO was at its very infancy then, and was something of an offshoot of DAO and RDO, nevertheless it represented a new bold direction. Each subsequent version of the technology leads us one step closer to ADO 2.6, when development came to an end. At this point, emerging from the shadows came the most revolutionary framework to date - .NET, with it the very powe...

One topic that keeps coming up in our forums and in newsgroups could be phrased as “how can I prevent users from updating data that another user is editing”. Usually this revolves (incorrectly) around the idea that you should have some way to “lock” a table or tables while a user is editing same. However, the “disconnected data” paradigm of ADO.NET makes this approach both unrealistic and in many cases, unfeasible....

Connected operations in ADO.NET are data access scenarios that require tight binding and open connection to the data source while working with the connected subset of the ADO.NET object model. This is in contrast to the round-tripping and client manipulation of the DataSet, which is the disconnected data vehicle of choice in ADO.NET....

Read Reviews | Write Review |  Your Rating: 

Disconnected operations in ADO.NET consist of data access scenarios that don't require the maintenance of an open database connection while working with data. This contrasts with the connected operations discussed in the preceding article in this series, which utilize the DataReader and Command classes. The primary vehicle for working with disconnected operations is the DataSet; it allows us to connect to a data source, manipulate the DataSet offline, and later reconnect to update the data sourc...

The Windows Forms DataGrid control provides a user interface to ADO.NET datasets, displays ADO.NET tabular data in a scrollable grid, and allows for updates to the data source. In cases where the DataGrid is bound to a data source with a single table containing no relationships, the data appears in simple rows and columns, as in a spreadsheet.As soon as the DataGrid control is set to a valid data source, the control is automatically populated, by creating columns and rows based on the structure ...
