SQLite: A Database Engine Shaped by Tcl

SQLite, the world's most widely used database engine, owes a significant debt to the Tcl programming language. While modern SQLite is a standalone C library independent of Tcl internally, its development process remains heavily reliant on Tcl. From test case creation and code generation to documentation and development tools, Tcl plays a crucial role. The author, drawing on 17 years of SQLite development experience, argues for Tcl's efficiency-boosting capabilities and suggests that without Tcl, SQLite's success would be unimaginable.
