Its development was based on a relational modeling system proposed by computer science pioneer Dr. E.F. Codd.<\/p>\r\n<p>Today, data scientists, software developers, and IT professionals mainly use SQL to query or update databases.<\/p>\r\n<p>Tech insiders widely consider SQL a relatively easy programming language to learn. It also has extensive applications, including nontechnical roles at the management and executive levels.<\/p>\r\n<p>This guide offers a detailed overview of SQL in computer programming. Below, we'll cover where students and working professionals can learn SQL computer programming, and how SQL fits into a career profile.<\/p>\r\n\r\n\r\n\r\n\r\n\n  \n  \n  <a class=\"subnav-waypoint\" name=\"what-is-sql\" id=\"what-is-sql\"><\/a>\n\n \r\n<h2>What Is SQL?<\/h2>\r\n<p>SQL allows users to retrieve and process information from relational databases. Relational databases are structured data collections that document information in tables.<\/p>\r\n<p>SQL supports many types of relational database operations, including:<\/p>\r\n<ul>\r\n<li>Searching for and retrieving information<\/li>\r\n<li>Adding, removing, or updating data<\/li>\r\n<li>Improving database accuracy and performance<\/li>\r\n<\/ul>\r\n\r\n\r\n<p>As a widely used standard, SQL has multiple important applications:<\/p>\r\n\r\n<div class=\"bg-primary-light rounded-lg border-thin py-1 px-6 mb-6\">\r\n<h3 class=\"text-primary-800\">Relevance in Common Database Management Systems<\/h3>\r\n<p>Many common database management systems support SQL. Examples include MySQL, Microsoft SQL Server, Amazon Redshift, PostgreSQL, Oracle.<\/p>\r\n<\/div>\r\n\r\n<div class=\"bg-primary-light rounded-lg border-thin py-1 px-6 mb-6\">\r\n<h3 class=\"text-primary-800\">Integration with Multiple Programming Languages<\/h3>\r\n<p>In professional settings, SQL often pairs with other <a href=\"\/resources\/computer-programming-languages\/\">common programming languages<\/a>. Combining SQL with languages such as Java, Scala, or Python enables programmers to create powerful, efficient, and customized data retrieval and processing solutions.<\/p>\r\n<\/div>\r\n\r\n\r\n<div class=\"bg-primary-light rounded-lg border-thin py-1 px-6 mb-6\">\r\n<h3 class=\"text-primary-800\">Nontechnical Uses<\/h3> \r\n<p>Business strategists and analysts use SQL to inform deep, original research. Process engineers draw on it for insights into areas of operational efficiency and weakness.<\/p>\r\n<\/div>\r\n\r\n\r\n\r\n<p>SQL continues to see new applications as businesses gather greater quantities of data. Its ability to quickly and efficiently return targeted libraries of data saves time and money. SQL also helps organizations identify and develop opportunities to build competitive advantages.<\/p>\r\n\r\n<div class=\"grid lg:grid-cols-3 gap-5 my-8\"> \n  \r\n\n<div class=\"sonic-interlink duration-500 flex hover:shadow-lg bg-secondary-700 \">\n    <a\n        target=\"_self\"\n        href=\"\/resources\/computer-programming-languages\/html\/\"\n        class=\"flex items-center p-8 relative rounded w-full transition-opacity duration-500 hover:opacity-75\">\n                <span class=\"text-white block w-full\">\n          <span class=\"interlink-content flex justify-between items-center\">\n            <div>\n                                                <span class=\"title leading-snug\">What is HTML?<\/span>\n                            <\/div>\n            <sonic-icon class=\"ml-3 md:ml-0\" icon=\"arrow-circle-right\" size=\"small\" color=\"#fff\"><\/sonic-icon>\n          <\/span>\n        <\/span>\n    <\/a>\n<\/div>\n\n\n\r\n\n<div class=\"sonic-interlink duration-500 flex hover:shadow-lg bg-secondary-700 \">\n    <a\n        target=\"_self\"\n        href=\"\/resources\/computer-programming-languages\/objective-c\/\"\n        class=\"flex items-center p-8 relative rounded w-full transition-opacity duration-500 hover:opacity-75\">\n                <span class=\"text-white block w-full\">\n          <span class=\"interlink-content flex justify-between items-center\">\n            <div>\n                                                <span class=\"title leading-snug\">What is Objective-C?<\/span>\n                            <\/div>\n            <sonic-icon class=\"ml-3 md:ml-0\" icon=\"arrow-circle-right\" size=\"small\" color=\"#fff\"><\/sonic-icon>\n          <\/span>\n        <\/span>\n    <\/a>\n<\/div>\n\n\n\r\n\n<div class=\"sonic-interlink duration-500 flex hover:shadow-lg bg-secondary-700 \">\n    <a\n        target=\"_self\"\n        href=\"\/resources\/python\/\"\n        class=\"flex items-center p-8 relative rounded w-full transition-opacity duration-500 hover:opacity-75\">\n                <span class=\"text-white block w-full\">\n          <span class=\"interlink-content flex justify-between items-center\">\n            <div>\n                                                <span class=\"title leading-snug\">Learn more about Python<\/span>\n                            <\/div>\n            <sonic-icon class=\"ml-3 md:ml-0\" icon=\"arrow-circle-right\" size=\"small\" color=\"#fff\"><\/sonic-icon>\n          <\/span>\n        <\/span>\n    <\/a>\n<\/div>\n\n\n\r\n\n<\/div>\n\r\n\r\n\r\n\r\n<sonic-editorial-listings degree=\"\" category=\"\" subject=\"\" limit=\"3\"><\/sonic-editorial-listings>\r\n\r\n\r\n\n  \n  \n  <a class=\"subnav-waypoint\" name=\"why-use-sql\" id=\"why-use-sql\"><\/a>\n\n \r\n<section class=\"-mx-4 md:-mx-1\/2vw py-12 md:py-16 mt-12 md:my-16 relative md:left-1\/2 md:right-1\/2 md:w-screen bg-gray-50\">\n    <div class=\"container content\">\n        \r\n<h2>Why Use SQL?<\/h2>\r\n<p>SQL ranks among the most <a href=\"\/resources\/best-programming-languages-to-learn\/\">widely used database languages<\/a> in computing.

Its longevity as a querying tool has made SQL a fixture in both corporate and institutional settings.<\/p>\r\n<p>Countless companies and organizations use SQL on a regular basis. Some particularly well-known and high-profile examples include:<\/p>\r\n<ul>\r\n<li>Accenture<\/li>\r\n<li>Adobe<\/li>\r\n<li>Intuit<\/li>\r\n<li>Microsoft<\/li>\r\n<li>Oracle<\/li>\r\n<li>Google<\/li>\r\n<li>Meta<\/li>\r\n<li>Amazon<\/li>\r\n<\/ul>\r\n\r\n\n  \n  \n  <a class=\"subnav-waypoint\" name=\"sql-vs-mongodb-xquery\" id=\"sql-vs-mongodb-xquery\"><\/a>\n\n \r\n<h3>SQL vs. MongoDB vs. XQuery<\/h3>\r\n<p>SQL databases use relational structures. These databases feature tables with vertical columns or attributes and horizontal rows. Many organizations use SQL databases, but there are alternatives such as NoSQL.<\/p>\r\n<p>NoSQL databases can be structured or unstructured. At first, they did not support SQL querying. Over time, many such databases began integrating SQL queries because of SQL's popularity. Professionals now use the term \"NoSQL\" to mean \"not only SQL.\"<\/p>\r\n<p><a href=\"\/careers\/\">Computer science professionals<\/a> can use numerous methods to query NoSQL databases that do not support SQL.<\/p>\r\n<p>In recent years, MongoDB has emerged as one of the more popular alternative database structures. MongoDB Query Language (MQL), now MongoDB Query API, executes queries in MongoDB databases.<\/p>\r\n<p>Developers are creating a language known as XQuery. Their goal is for XQuery to become a standardized language for querying both structured and unstructured databases.<\/p>\r\n<p>The following table compares key features of each of these three tools:<\/p>\r\n\r\n\r\n<table class=\"sonic-table\">\r\n<tbody>\r\n    <thead>\r\n<tr>\r\n<th style=\"background-color:#EEECF9\">\r\n<\/th>\r\n<th style=\"background-color:#EEECF9\">\r\n<strong>SQL<\/strong>\r\n<\/th>\r\n<th style=\"background-color:#EEECF9\">\r\n<strong>MQL<\/strong>\r\n<\/th>\r\n<th style=\"background-color:#EEECF9\">\r\n<strong>XQuery<\/strong>\r\n<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tr>\r\n<td>\r\n<p><strong>Popularity\/Usefulness<\/strong><\/p>\r\n<\/td>\r\n<td data-title=\"SQL\">\r\n<p>High<\/p>\r\n<\/td>\r\n<td data-title=\"MQL\">\r\n<p>Growing<\/p>\r\n<\/td>\r\n<td data-title=\"XQuery\">\r\n<p>Emerging<\/p>\r\n<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>\r\n<p><strong>Portability Across Operating Systems<\/strong><\/p>\r\n<\/td>\r\n<td data-title=\"SQL\">\r\n<p>Excellent<\/p>\r\n<\/td>\r\n<td data-title=\"MQL\">\r\n<p>Good<\/p>\r\n<\/td>\r\n<td data-title=\"XQuery\">\r\n<p>Evolving<\/p>\r\n<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>\r\n<p><strong>Required Skill Level<\/strong><\/p>\r\n<\/td>\r\n<td data-title=\"SQL\">\r\n<p>Suitable for users of all skill levels<\/p>\r\n<\/td>\r\n<td data-title=\"MQL\">\r\n<p>Open to beginners but some supplementary computer science knowledge is helpful<\/p>\r\n<\/td>\r\n<td data-title=\"XQuery\">\r\n<p>Designed to optimize ease of use<\/p>\r\n<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>\r\n<p><strong>Support<\/strong><\/p>\r\n<\/td>\r\n<td data-title=\"SQL\">\r\n<p>Comprehensive<\/p>\r\n<\/td>\r\n<td data-title=\"MQL\">\r\n<p>Mostly community-based<\/p>\r\n<\/td>\r\n<td data-title=\"XQuery\">\r\n<p>Improving but limited<\/p>\r\n<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n\n    <\/div>\n<\/section>\n\r\n\r\n<sonic-editorial-listings degree=\"\" category=\"\" subject=\"\" limit=\"3\"><\/sonic-editorial-listings>\r\n\r\n\n  \n  \n  <a class=\"subnav-waypoint\" name=\"where-to-learn-sql\" id=\"where-to-learn-sql\"><\/a>\n\n \r\n<h2>Where Can You Learn SQL?<\/h2>\r\n<p>Undergraduate <a href=\"\/degrees\/computer-programming\/\">computer science degree programs<\/a> often include instruction in SQL and computer programming languages.
