[Handwritten database toadb] The content structure of the data dictionary and its generation avoid the chicken-and-egg problem and improve performance under high-frequency access.

411 The role of data dictionary

Column content :

• This column mainly introduces how to develop the handwritten database toadb
  from scratch, the steps of development, the principles involved in the development process, problems encountered, etc., so that everyone can keep up and develop together, so that everyone who needs it can become a participant .
  This column will be updated regularly, and the corresponding code will also be updated regularly. The code at each stage will be tagged to facilitate learning at each stage.

Preface

---

This column introduces hand-writing a database kernel from scratch. By building a simple database kernel model, we avoid the huge code volume and numerous functions of open source databases. Toadb simplifies the complexity and displays the core modules of the database even though it is small. The principles and processes can also deepen the understanding of database principles and improve programming and architecture design capabilities.
