The .sqlite file extension typically indicates a database file created using the SQLite database management system. SQLite is a self-contained, serverless, zero-configuration, transactional SQL database engine. Unlike client-server database systems, SQLite reads and writes directly to ordinary disk files. A complete SQLite database is stored in a single cross-platform disk file. This makes it highly portable and easy to embed in applications. SQLite is widely used in embedded systems, mobile applications, desktop software, and web browsers. The file contains the entire database, including tables, indices, views, and triggers. Because of its simplicity and ease of use, SQLite is a popular choice for applications that require local data storage without the overhead of a full-fledged database server. It is often used for storing application settings, user data, and other persistent information. The file format is well-documented and supported by numerous programming languages and tools, making it a versatile option for various data storage needs. The data within the file is organized according to the SQLite database schema defined when the database was created.
