深入探讨 SQLAlchemy，这是一个流行的开源代码库，可帮助 Python 程序员处理 Oracle、MySQL、PostgresSQL 和 SQLite 等关系数据库。本实用指南通过实际案例，向您展示如何使用 SQLAlchemy 构建一个简单的数据库应用程序，以及如何使用相同的元数据同时连接多个数据库。
SQL 是一种用于查询和操作数据的强大语言，但很难与您的应用程序集成。SQLAlchemy 可帮助您将 Python 对象映射到数据库表，而无需大幅更改现有的 Python 代码。如果您是具备基本 SQL 语法和关系理论知识的中级 Python 开发人员，本书可作为学习工具和实用参考。
《SQLAlchemy 核心》包含以下几个部分：
- SQLAlchemy 核心：使用 SQL 表达式语言以 Python 方式为您的应用程序提供数据库服务
- SQLAlchemy ORM：使用对象关系映射器将数据库模式和操作与应用程序中的数据对象绑定
- Alembic：使用这个轻量级数据库迁移工具，处理应用程序演进过程中数据库的变更
- 食谱：学习如何将 SQLAlchemy 与 Flask 等 Web 框架和 SQLAcodegen 等库一起使用
