## What it is
A curated series of in-depth notes and tutorials on database theory and practice, covering relational, document, key-value, NewSQL, search engines, data warehouses, and OLAP systems. It is a Chinese-language knowledge repository (part of the NGTE Books series) rather than runnable software.

## Use cases
- learn how relational databases like MySQL and PostgreSQL work internally
- understand differences between SQL, NoSQL, document, and key-value stores
- study NewSQL systems like TiDB, OceanBase, and Spanner
- prepare for database engineering interviews
- get an overview of data warehouses and OLAP concepts
- understand multi-model database architectures

## When to choose
- you want structured reading material on database theory and internals
- you need a broad survey of database types from relational to NewSQL
- you prefer Chinese-language technical notes

## When to avoid
- you need runnable code, drivers, or tools rather than documentation
- you need up-to-date official documentation for a specific database version
- you require English-language resources only

## Facets
- artifact type: learning-resource
- maturity: active
- function: database, search-engine, documentation
- domain: databases, big-data, developer-tools, tutorials
- platform: -
- tags: notes, database-internals, mysql, postgresql, newsql, olap, nosql, data-warehouse, chinese-language, web-server
