What Company Developed SQL? Embark on a historical journey to unravel the company responsible for unleashing the power of SQL.
SQL: The Evolution of a Game-Changing Language
Developed by IBM: SQL, originally known as SEQUEL, was birthed in the laboratories of IBM during the 1970s. The aim was to create a language that would interface effectively with IBM’s relational database management system (RDBMS).
Standardized by ANSI and ISO: The 1980s saw SQL gain universal recognition, with standardization by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). Today, a variety of database management systems, including MySQL, Microsoft SQL Server, and Oracle Database, utilize SQL.
Declarative Programming Language: One of SQL’s distinct features is its nature as a declarative programming language. This means SQL clearly articulates the desired results of a computation, while the steps to achieve these results are not specified.
Consider an example SQL statement:
SELECT name FROM table ORDER BY name;This statement expresses the intent to sort the “name” column in alphabetical order. It leaves the method of sorting up to the database management system. Importantly, despite the method chosen, all SQL implementations must yield the same results for a given SQL statement.

SQL has three main components:
Shape Your Database with Data Definition Language (DDL): Take control of your database’s architecture by creating and modifying structures like tables and indexes – the foundation of your data ecosystem.
Interact with Your Data using Data Manipulation Language (DML): Dive into the heart of your database, inserting, updating, and deleting data, ensuring your information remains fresh and relevant.
Govern Access with Data Control Language (DCL): Master the art of authority in your database, granting and revoking permissions on database objects – the gatekeeper of your precious data assets.
DDL statements are typically used to create or modify database structures. For example, the following SQL statement creates a new table called “employees”:
CREATE TABLE employees (
id INTEGER PRIMARY KEY,
name TEXT,
salary REAL
);DML statements are used to insert, update, and delete data in a database. For example, the following SQL statement inserts a new row into the “employees” table:
INSERT INTO employees (name, salary) VALUES ('John Smith', 30000);The UPDATE and DELETE statements can be used to modify existing data in a database. For example, the following SQL statement updates the “salary” column for all employees with the last name “Smith”:
UPDATE employees SET salary = 40000 WHERE last_name = 'Smith';Finally, DCL statements are used to grant and revoke permissions on database objects. For example, the following SQL statement grants the “SELECT” permission on the “employees” table to the user “jsmith”:
GRANT SELECT ON employees TO jsmith;SQL is a powerful and versatile language that can be used to perform a wide variety of tasks on a database. In addition to the standard SQL commands, most database management systems also offer a set of proprietary extensions that add new features and capabilities to the language.
What is the History Behind SQL?
What Company Developed SQL? Discover the industry titan whose ingenuity laid the foundation for SQL’s universal dominance in data management.
Let’s take a step back in time to the 1970s, where at the heart of IBM, Dr. E. F. Codd crafted what we now know as SQL. Short for Structured Query Language, SQL is the recognized standard for interacting with and manipulating databases.
Originally, SQL’s design complemented the relational model of databases. Much like neatly organized folders in a filing cabinet, the relational model arranges data into tables. Imagine a table as a detailed directory, storing key information – a list of employees with their respective contact details, for instance.
But, data doesn’t exist in isolation. The beauty of the relational model lies in its ability to create relationships between tables. Think of an employee linked to their manager. These links, or foreign key constraints, form the essence of relational databases. SQL was sculpted to efficiently navigate and manipulate this web of related data.
