chidb

χdb (chidb in plain ASCII) is a didactic relational database management system (RDBMS) designed for teaching how a RDBMS is built internally, from the data organization in files all the way up to the SQL parser and query optimizer. The design of χdb is based on SQLite, with several simplifying assumptions that make it possible to develop a complete χdb implementation over the course of a quarter or semester.
