It is a programming language used to manage and work with data stored in databases. SQL helps users store, retrieve, update, and delete data easily. It is mainly used with relational database management systems such as MySQL, Oracle, SQL Server, and PostgreSQL.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SQL AS A DATABASE LANGUAGE<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In simple words, SQL is the language that allows us to communicate with a database. When we want to see specific information, add new records, change existing data, or remove data, we use SQL commands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>IMPORTANCE OF SQL IN WEBSITES<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Databases are used in almost every website and application. For example, when a user creates an account on a website, their information such as name, email, and password is stored in a database. SQL is used to manage and access this information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>MAIN FUNCTIONS OF SQL<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are several basic functions that SQL performs. It can create databases and tables, insert new data into tables, retrieve data from tables, update existing information, and delete unnecessary records. SQL can also control access to the data so that only authorized users can view or modify it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>WHY SQL IS IMPORTANT<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SQL is widely used because it is simple to learn and very powerful. It works with large amounts of data and allows users to organize information efficiently. Many developers, data analysts, and database administrators use SQL as an important tool in their work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CONCLUSION<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Learning SQL is useful for anyone who wants to work in web development, data analysis, or database management. It is one of the most important skills in the field of technology and data management.<\/p>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1773298994601\"><strong class=\"schema-faq-question\"><\/strong> <p class=\"schema-faq-answer\"><\/p> <\/div> <\/div>\n\n\n<div class=\"yoast-breadcrumbs\"><span><span><a href=\"https:\/\/gigz.pk\/sql\/\">Home<\/a><\/span> \u00bb <span class=\"breadcrumb_last\" aria-current=\"page\">SQL Foundations Program (SQL-101) > Introduction to Databases > What is SQL?<\/span><\/span><\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"menu_order":3,"template":"","class_list":["post-55","lesson","type-lesson","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What is SQL? - SQL Learning Hub<\/title>\n<meta name=\"description\" content=\"Learn SQL basics and database management.
