ADO. NET Architecture Microsoft Docs. Data processing has traditionally relied primarily on a connection based, two tier model. As data processing increasingly uses multi tier architectures, programmers are switching to a disconnected approach to provide better scalability for their applications. ADO. NET Components The two main components of ADO. NET 3. 0 for accessing and manipulating data are the. NET Framework data providers and the Data. Set. NET Framework Data Providers The. NET Framework Data Providers are components that have been explicitly designed for data manipulation and fast, forward only, read only access to data. The Connection object provides connectivity to a data source. The Command object enables access to database commands to return data, modify data, run stored procedures, and send or retrieve parameter information. The Data. Reader provides a high performance stream of data from the data source. Finally, the Data. Adapter provides the bridge between the Data. Set object and the data source. KB/database/Adonet/ADONETArchitecture.JPG' alt='Vb.Net Architecture Pdf' title='Vb.Net Architecture Pdf' />The Data. Adapter uses Command objects to execute SQL commands at the data source to both load the Data. Set with data and reconcile changes that were made to the data in the Data. Set back to the data source. For more information, see. NET Framework Data Providers and Retrieving and Modifying Data in ADO. Pearl In The Mist here. NET. The Data. Set The ADO. NET Data. Set is explicitly designed for data access independent of any data source. As a result, it can be used with multiple and differing data sources, used with XML data, or used to manage data local to the application. The Data. Set contains a collection of one or more Data. Vb Net BasicsTable objects consisting of rows and columns of data, and also primary key, foreign key, constraint, and relation information about the data in the Data. Table objects. For more information, see Data. Sets, Data. Tables, and Data. Views. The following diagram illustrates the relationship between a. NET Framework data provider and a Data. Set. ADO. NET architecture Choosing a Data. Vb.Net Architecture Pdf' title='Vb.Net Architecture Pdf' />Reader or a Data. Set When you decide whether your application should use a Data. Reader see Retrieving Data Using a Data. Reader or a Data. Set see Data. Sets, Data. Tables, and Data. Views, consider the type of functionality that your application requires. Use a Data. Set to do the following Cache data locally in your application so that you can manipulate it. If you only need to read the results of a query, the Data.

Remote data between tiers or from an XML Web service. Interact with data dynamically such as binding to a Windows Forms control or combining and relating data from multiple sources. Perform extensive processing on data without requiring an open connection to the data source, which frees the connection to be used by other clients. If you do not require the functionality provided by the Data. Set, you can improve the performance of your application by using the Data. Reader to return your data in a forward only, read only manner. Although the Data. Adapter uses the Data. Reader to fill the contents of a Data.

Net is a simple, modern, objectoriented computer programming language developed by Microsoft to combine the power of. NET Framework. Set see Populating a Data. Set from a Data. Adapter, by using the Data. Reader, you can boost performance because you will save memory that would be consumed by the Data. Set, and avoid the processing that is required to create and fill the contents of the Data. Set. LINQ to Data. Set LINQ to Data. Set provides query capabilities and compile time type checking over data cached in a Data. Set object. It allows you to write queries in one of the. NET Framework development language, such as C or Visual Basic. For more information, see LINQ to Data. Set. LINQ to SQL LINQ to SQL supports queries against an object model that is mapped to the data structures of a relational database without using an intermediate conceptual model. Each table is represented by a separate class, tightly coupling the object model to the relational database schema. LINQ to SQL translates language integrated queries in the object model into Transact SQL and sends them to the database for execution. When the database returns the results, LINQ to SQL translates the results back into objects. For more information, see LINQ to SQL. ADO. NET Entity Framework The ADO. NET Entity Framework is designed to enable developers to create data access applications by programming against a conceptual application model instead of programming directly against a relational storage schema. The goal is to decrease the amount of code and maintenance required for data oriented applications. For more information, see ADO. NET Entity Framework. WCF Data Services WCF Data Services is used to deploy data services on the Web or an intranet. The data is structured as entities and relationships according to the specifications of the Entity Data Model. Data deployed on this model is addressable by standard HTTP protocol. For more information, see WCF Data Services 4. XML and ADO. NET ADO. NET leverages the power of XML to provide disconnected access to data. ADO. NET was designed hand in hand with the XML classes in the. NET Framework both are components of a single architecture. ADO. NET and the XML classes in the. NET Framework converge in the Data. Set object. The Data. Set can be populated with data from an XML source, whether it is a file or an XML stream. The Data. Set can be written as World Wide Web Consortium W3. C compliant XML that includes its schema as XML schema definition language XSD schema, regardless of the source of the data in the Data. Set. Because of the native serialization format of the Data. Set is XML, it is an excellent medium for moving data between tiers, making the Data. Set an optimal choice for remoting data and schema context to and from an XML Web service.
