I wrote a RDBMS (SQLite clone) from scratch in pure Python

In this web content, the author introduces the LearnDB project, which aims to deepen the understanding of databases by creating a relational database management system (RDBMS) similar to SQLite from scratch. The project is written in pure Python and has a relatively simple codebase, making it ideal for tinkering. However, it is not recommended for actual storage solutions due to its limitations, such as simplified floating-point number arithmetic and lack of support for wildcard column expansion. The content provides instructions for getting started with LearnDB, including tutorials, reference manuals, and installation steps. The author also mentions the references consulted, including a tutorial and resources on SQLite and Postgres.
