What are the advantage of ADO.Net
ADO.NET is the common name for the classes and interfaces of the namespace System.Data. ADO.NET data components in Visual Studio environment encapsulate data access functionality in various ways that help you to develop applications more easily and with fewer errors.
ADO.Net offers performance advantages by its Disconnected Architecture, it is a remarkably efficient and scalable architecture. The DataSet class in ADO.Net operates in an entirely disconnected nature. This model allows for the DataSet class to be unaware of the origin of its data source, an unlimited number of supported data sources can be plugged into code without any hassle in the future
ADO.NET programs can take advantage of the flexibility and broad acceptance of Extensible Markup Language (XML). XML is the format for transmitting datasets across the network, so any component that can read the XML format can process data. In fact, many of the classes in ADO.NET, like the DataSet, are so intertwined with XML that they simply cannot exist or function without utilizing the technology.
The role of ADO.NET data providers is to permit direct manipulation of data through SQL. ADO.NET includes a SQL Server Data Provider that is highly optimized for interaction with SQL Server. It uses SQL Server's own Tabular Data Stream (TDS) format for exchanging information. This is deftly handled by the Advantage ADO.NET Data Provider.
Another advantage of ADO.NET is its rich object model. The entire ADO.NET architecture is built on a hierarchy of class inheritance and interface implementation. Once you trace for things you need within this namespace, you can find that the logical inheritance of features and base class support makes the entire system extremely easy to use.
