This article introduces the relevant knowledge of "what are the skills of ADO.NET database first?". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

ADO.NET database is a new database access model redesigned by Microsoft for the defects of ADO. It supports industry standards and integrates all the types used for data processing. This paper discusses the structure and main objects of ADO.NET database. The remarkable feature of ADO.NET database is that it combines XML technology and realizes under the concept of disconnection.

Database access based on multi-tier architecture is specially designed for Web. Taking the reservoir hydrology WDS database of the Institute of Hydrology of Nanjing Institute of Automation as an example, this paper discusses the way of accessing the database by using ADO.NET database technology, which provides the data basis for the development of power grid water regulation automation system using .NET (ASP.NET).

Introduction ADO.NET database is the development product of ADO and has more versatility. Its emergence has opened up a new era of data access technology. Database access based on Web is a current data access technology. It not only successfully realizes the access of the client to the database on the server when the network is disconnected and the Web page is stateless, but also does not require developers to do a lot of work [1].

ADO.NET database is a new database access mechanism developed by Microsoft under. Net platform [2]. Compared with ADO, ADO.NET database meets three important requirements that ADO can not meet: it provides a disconnected data access model to meet the programming needs of Web environment; provides tight integration with .NET; and provides a seamless connection with .NET framework. In terms of performance, because ADO uses COM marshaling to pass between layers.

ActiveX Data Object (ADO for short) is a data access model provided by Microsoft. According to this model, the database can be easily operated. At the same time, ADO is supported by all the development tools of Microsoft, so it can be used by VB, VC and ASP development. So to develop ASP database applications, you only need to embed SQL (structured query language) commands in the code.

Users can easily enter, update, and delete background database records. When the browser of the client fills out the information required by the form and presses the "Submit" button, it sends the HTTP request to the WEB server through the Internet and the intranet, where the request executes an Active Server Pages program specified in the form (a document with the suffix .ASP).

The ADO.NET database is not just a simple upgrade to ADO, it is an important part of Microsoft's .NET strategy, so how is it different from before? Let this article tell you now.

In the past, the main method of data processing in ADO was OLEDB, and now the same is true in ADO.NET databases. However, in order to better support the two widely used databases, Oracle and SQL Server, Microsoft has made special extensions to OLEDB, which are OracleClient and SQLClient respectively. Of course, because there are many database products, in order to facilitate the previous OLEDB program upgrade, OLEDB itself has also been upgraded. Represented as an OLEDB class in .net.
