Database is a fundamental element for the development of sites and web systems. It is responsible for storing, organizing and managing information in a structured and secure way. In HTML, it is possible to create pages that interact with databases, allowing users to view, insert, change or delete information from a system.
To create a database in HTML, it is necessary to use a programming language such as PHP, which allows the connection to the database and the execution of SQL commands. SQL is a structured query language that allows you to create, read, update, and delete records in a database.
To create a database, it is necessary to define the structure of the table, which is composed of columns and rows. The columns represent the table's fields, such as name, age, e-mail, telephone, among others. The lines represent the records, that is, the information that will be stored in the database.
To create a table in HTML, you must use the <table> tag, which defines the structure of the table. Within the <table> tag, it is possible to create the columns using the <th> tag, which represents the column header. Rows are created with the <tr> tag, and cells with the <td> tag.
In addition, it is possible to use the JavaScript programming language to create interactions with the database in real time. With JavaScript, it is possible to create forms that allow the insertion of information in the database, as well as the updating and deletion of records.
In summary, the database is an essential tool for the development of websites and web systems. In HTML, it is possible to create pages that interact with the database, allowing users to view, insert, change or delete information from a system. For this, it is necessary to use programming languages such as PHP and JavaScript, which allow the connection and interaction with the database.
