ASP.NET is a relatively popular technology for making dynamic web pages. Using VBScript, JavaScript and other simple and easy-to-learn scripting languages, combined with HTML code, the application program of the system can be completed quickly without compilation and easy writing, and can be directly executed on the server side. Using a common text editor, such as Windows Notepad, you can edit the design. Regardless of the browser, the browser used by the client can browse the webpage content designed by ASP.NET as long as it can execute HTML code. The scripting languages (VBScript, JavaScript) used by ASP.NET are all executed on the Web server, and the browser of the client does not need to be able to execute these scripting languages. ASP.NET can be compatible with any Active Scripting language. Besides VBScript or JavaScript, it can also use other scripting languages provided by third parties, such as REXX, Perl, Tcl, etc. through plug-in.SQL, as a database developed by Microsoft on Windows series platform, has won the favor of many users for its ease of use once it is launched.

Different from FoxPro database, SQL is a database management system with complete functions. It includes support for the development of engines, standard SQL language, extended features (such as replication, OLAP, analysis) and other functions.
