SQL stands for "Structured Query Language." It is a domain-specific language used for managing and manipulating relational databases. SQL provides a standardized way to interact with databases, enabling users to create, retrieve, update, and delete data. It is widely employed for tasks such as database design, data querying, and data manipulation. SQL is not limited to a specific database system and is supported by various database management systems (DBMS) like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. Common SQL operations include SELECT (querying data), INSERT (adding new data), UPDATE (modifying existing data), and DELETE (removing data).
-- Selecting data from a table
SELECT FirstName, LastName FROM Employees WHERE Department = 'IT';
-- Inserting new data
INSERT INTO Customers (CustomerID, CustomerName, Email) VALUES (1, 'ABC Company', 'abc@example.com');
-- Updating existing data
UPDATE Products SET Price = 29.99 WHERE ProductID = 101;
-- Deleting data
DELETE FROM Orders WHERE OrderID = 500;
Declarative Language: SQL is a declarative language, meaning users specify the result they want, and the database management system determines the best way to retrieve it.
Scalability: SQL databases can handle large amounts of data and scale well with the growth of data and users.
Data Integrity: SQL supports constraints and relationships, ensuring the integrity of data stored in the database.
Interoperability: SQL is supported by a wide range of database systems, promoting interoperability across different platforms.

HTML stands for "Hypertext Markup Language." It is the standard markup language for creating and structuring web pages and web applications. HTML utilizes tags to define elements on a web page, such as headings, paragraphs, images, links, and more. Web browsers interpret HTML code to render the visual presentation of a page, incorporating text, images, and multimedia elements. HTML forms the backbone of the World Wide Web and serves as a fundamental building block for creating content and interactivity on websites. HTML files commonly use the ".html" file extension. The MIME type for HTML is "text/html."
<!DOCTYPE html> <html> <head> <title>My First Web Page</title> </head> <body> <h1>Hello, World!</h1> <p>This is a sample HTML page.</p> </body> </html>
Standardization: HTML provides a standardized way to structure and present content on the web, ensuring consistency across different browsers.
Accessibility: HTML supports the creation of accessible content, making it possible for users with disabilities to navigate and understand web pages.
Interactivity: HTML, combined with CSS and JavaScript, enables the development of interactive and dynamic web pages.
Global Compatibility: HTML is universally supported by web browsers, making it a versatile and widely adopted technology.
