WebSQL

WebSQL was a deprecated API for client-side database storage in web browsers. It allowed developers to interact with an SQL database using synchronous queries, providing a simple way to store and retrieve structured data within the browser.

However, due to lack of standardization and browser support, it is no longer recommended for new development. Developers are encouraged to use modern alternatives like IndexedDB for client-side storage.

Example

-- Example SQL queries that might have been used with Web SQL
CREATE TABLE Books (id INTEGER PRIMARY KEY, title TEXT, author TEXT, genre TEXT);
INSERT INTO Books (title, author, genre) VALUES ('Sample Book', 'Author Name', 'Fiction');
SELECT * FROM Books WHERE author = 'Author Name';
