This article will explain in detail what ADO. NET solution means, Xiaobian thinks it is quite practical, so share it with you as a reference, I hope you can gain something after reading this article.

ADO. NET solution is to express the data in memory (that is, data sets) as XML, and then pass it to other components in XML format, but only if you have a deep understanding of exactly what FrontPage server is and how it works.

In fact, the component that accepts data doesn't have to be an ADO. NET component; it can be a Microsoft Visual Studio based solution or any application running on another platform. Programmability With Visual Studio. NET, you can program your objects instead of a single data table or column. ADO. NET uses strongly typed programming to better represent business objects.

For example, the ADO. NET schema is used in the following line of code using traditional programming (not strongly typed)IF TotalCost > Table("Customer").Column("Availability Credit") In this example, ADO tables and columns are programmed in an associative, abstract manner.

If you use strongly typed programming, things are much simpler: IF TotalCost > Customer. Available Credit In addition to being easier to read, strongly typed code is easier to write.

In particular, depending on the automatic complement of statements, you can write programs that recognize ADO. NET. As you can see in the following example, IntelliSense technology makes it easy to find tables related to Customers.

In addition, strongly typed datasets have a higher execution speed because the application ADO. NET schema does not have to look in the ADO object collection every time it accesses a data member. Using Data Sets The most important aspect of any ADO. NET application is the data set. A dataset is a copy of database data.

A data set can contain any number of data tables, each typically corresponding to a table or view in the database for an ADO. NET schema. Data sets form a single, unjoined view of database data. That is, it is in memory and does not maintain an active connection to the database containing the corresponding table or view. This disconnected architecture allows database server resources to be used only when reading or writing to the database, thus providing better scalability.
