第 11 章 續存和資料庫
Python 標準程式庫並沒有內附 RDBMS 介面。然而，有許多第三方模組都
能讓你的 Python 程式存取特定的 RDBMS。這種模組大多都遵循 Python
Database API 2.0（
https://www.python.org/dev/peps/pep-0249/
）標準，也稱
為
DBAPI
。本章涵蓋 DBAPI 標準，並提及實作它的幾個最流行的第三方
模組。
有一個 DBAPI 模組特別的方便，因為它附在每個 Python 標準安裝中：
sqlite3（
https://docs.python.org/3/library/sqlite3.html
）， 它包裹了SQLite

DB 引擎」，是世界上最廣為部署的關聯式 DB 引擎。我們會在後面的
「SQLite」中涵蓋
sqlite3
。
除了關聯式 DB，還有本章中所涵蓋的較為簡單的做法，另外還存在
Python 限定的物件 DB，例如 ZODB（
http://www.zodb.org/en/latest/
），以及
許多 NoSQL（
