XML

Extensible Markup Language (XML) is an abbreviation for Extensible Markup Language. It is a text-built markup language based on the Standard Generalized Markup Language (SGML).

Unlike HTML tags, which define how to show the data, XML tags describe the data and are used to store and arrange it rather than defining how to display it. XML will not replace HTML in the immediate future, but it will add new possibilities by incorporating several successful HTML features.



JSON

JSON is an abbreviation for JavaScript Object Notation. JSON is a lightweight data storage and transport format. When data is transmitted from a server to a web page, JSON is often used. JSON is "self-describing" and simple to grasp.



AJAX

AJAX stands for Asynchronous JavaScript. AJAX is a methodology for designing interactive and fast-loading websites. AJAX enables asynchronous web page updates by sharing tiny volumes of data with the server behind the scenes. This ensures that portions of a web page can be updated without reloading the whole page.

I learn to be more patient with every work that is assigned to me, to be polite and modest with everyone with whom I contact, and, most importantly, to LOVE MY WORK. The training helped me un

It is the basic language for relational database management systems, according to ANSI (American National Standards Institute). SQL statements are used to do things like update data on a database or extract data from a database. SQL Partitions The SQL language is divided into three parts: DML is used to retrieve and edit data in a table, such as inserting, deleting, and updating records. On the other hand, Select becomes a special declaration in this subset despite being a read-only instruction that does not modify data at all. DCL is used to manage access to data in a network, such as granting or robbing other users' privileges to execute specific tasks. DDL is used to describe data structures, such as creating, altering, or deleting tables. TCL commands, or transaction management language commands, deal with databas
