How to connect to database in html

HTML, as a web page markup language, is not direct for database operations. It requires other technologies to interact with the database. If you want to connect HTML to a database, you need to use a server-side language.

Generally, for the connection between HTML and database, we adopt the following method:

1. Use server-side scripting language

Use server Terminal scripting languages, such as PHP, ASP, JSP, etc., realize the connection with the database. These server-side scripting languages ​​can interact with the database in various ways.

You can use the database extension libraries provided by PHP, such as mysql, mysqli, PDO, etc., to connect to databases such as MySQL and MariaDB. You can also use ADO (ActiveX Data Objects) provided by ASP, JDBC (Java Database Connectivity) provided by JSP and other technologies to complete database connection related operations.

2. Using AJAX technology

AJAX is an asynchronous web page interaction technology that can achieve asynchronous interaction with the server through the XMLHttpRequest object. Through the cooperation of AJAX and server-side scripting language, the interaction between HTML and database can be realized.

Send a request to the server-side script through AJAX to interact with the database. The server-side script handles the request and returns the results to the client, ultimately dynamically updating the page data through JavaScript.

3. Using Web Services

A Web service is an independent, network-based, distributed, reusable application that can be accessed through SOAP (Simple Object Access Protocol), XML-RPC (XML-based remote procedure call) and other network protocols achieve cross-platform and cross-language interoperability.

Using web services, you can interact with the database by sending requests to server-side scripts through the SOAP protocol. Web services provide standards-based, universal interfaces that can be used by a variety of programming languages ​​and development platforms.

In general, the connection between HTML and database requires the use of server-side language. When choosing a server-side language, you need to consider factors such as compatibility with the database, performance, and security. At the same time, you also need to consider specific business needs and try to choose a server-side language that corresponds to the functions.
