Reverse-Engineering SQLite: Decoding Database Files Byte by Byte

SQLite is ubiquitous yet remains opaque to most developers—built into billions of devices worldwide, but rarely understood at the code level. This article decodes the .db file format through reverse engineering, transforming abstract database concepts into concrete C++ implementations. The byte-level insights are invaluable for optimizing queries, debugging issues, and mastering how storage systems fundamentally work.
