Exploration into the critical subsystems of SQLite that are frequently overlooked during initial implementation. We will examine the nuances of referential integrity enforcement, the mechanics of Write-Ahead Logging (WAL) for concurrent access, and the strategies for managing disk footprint through vacuuming.

This is continuation of discussion about SQLite pitfalls.

SQLite is the world’s most widely used database, powering the backends of countless applications. For most software, it offers a reliable solution for embedded data storage, eliminating the need to reinvent the wheel. Its broad adoption means developers benefit from a well-documented, dependable tool with a familiar SQL dialect.
