What is MIME type "application/x-sqlite3"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type application/x-sqlite3 marks files that implement the SQLite database engine. It stores structured, relational data in a single, portable file. This design skips the need for a separate server.

It is used in many desktop apps, mobile software, and embedded systems. The engine handles SQL queries, transactions, and data integrity in a lightweight package.

• Main purpose: Supports efficient local data storage and management in applications.
• Key features: - Embeds a complete SQL database in one file.
  - Ensures transactional integrity and ease of backup.
• File usage: Standard database files appear as DB, SQLITE, DB3, or SQLITE3 files.
  Supporting files include transaction logs like DB-WAL and SQLITE-WAL, and shared memory segments such as DB-SHM and SQLITE-SHM.
  Other variants include archive bundles (SQLAR) and Fossil repository files (FOSSIL).

This MIME type guides programs to handle these files correctly. For detailed technical information, check out the SQLite official site.
