                            The XML (Extensible Markup Language) markup language offers a set of rules for encoding texts in a human-readable and machine-readable manner. XML is used to store and organize data rather than dictating how it should be displayed, like HTML elements do.              JSON (JavaScript Object Notation) is a data-exchange format that is simple to use. Reading and writing are simple tasks for humans. Machines can easily parse and produce it. When data is transmitted from a server to a web page, this is commonly utilized.              AJAX (Asynchronous JavaScript and XML) is a collection of web development approaches that generate asynchronous online applications by utilizing a variety of client-side web technologies. Ajax allows web applications to transmit and retrieve data from a server asynchronously without interfering with the existing page's appearance and functionality.

                   SQL stands for Structured Query Language. It is a standard language for storing, manipulating and retrieving data in a Relational Database Management System. The standard SQL commands are the following: "Select" for display, "Insert" for adding a new record in the table, "Update" to change the value of one field or more, "Delete" to delete a record, "Create" to add new table/field/database, and "Drop" to delete the existing table/field/database.
