基础设施即代码（IaC）自约 25 年前诞生以来，已经彻底改变了我们管理和部署基础设施资源的方式。这种方法通过引入版本控制、自动部署和一致的环境，将基础架构配置视为代码。数据库即代码（Data-as-Code，DaC）将这些相同的原则延伸到数据库模式管理中，将版本控制和部署自动化的优势带到任何应用程序堆栈中最关键的组件之一。
关于数据库即代码的基础知识
数据库即代码代表了一种全新的数据库管理方法，它摆脱了传统的手动做法。DaC 不是手动执行 SQL 脚本或使用图形工具修改数据库模式，而是将数据库结构和更改视为代码工件，可以通过自动化管道进行版本控制、审查和部署。
我们可以将其比作建造房屋：在传统的数据库管理中，不同的承包商会出现并在没有蓝图或文档的情况下进行更改。同时，数据库即代码就像拥有每个人都遵循的详细架构计划，每项更改在实施前都会被记录和批准。此方法可确保数据库架构在所有环境中以可预测且一致的方式发展。
核心原则涉及将所有数据库架构定义、迁移脚本和配置文件，与应用程序代码一起存储在版本控制系统中。这为你的数据库结构创建了单一事实来源，并使你能够准确跟踪数据库随时间的演变情况。
重要组件和实施方法
数据库即代码包含几个基本组件，这些组件协同工作以创建全面的数据库管理策略：
- 结构定义是其基础，通常用 SQL DDL（数据定义语言）语句编写，或用描述表结构、索引、约束和关系的领域特定语言编写。
- 迁移脚本处理数据库从一个版本到另一个版本的转换。这些脚本经过精心设计，尽可能向前和向后兼容，确保顺利部署和回滚功能。每个迁移都按顺序编号，并包含升级和降级说明。
- 部署自动化通过持续集成和持续部署（CI/CD）管道将所有内容联系在一起。这些自动化工作流验证架构更改，针对示例数据运行测试，并将批准的更改部署到目标环境。自动化可确保最大限度地减少人为错误，并确保所有环境保持同步。
- 版本控制集成允许团队像应用程序代码一样协作处理数据库更改。拉取请求支持对模式修改进行同行评审，并且可以采用分支策略来管理功能开发和修补程序。这种协作方法有助于在潜在问题到达生产环境之前发现它们。
工具和实施支持
现代数据库管理工具已经发展到可以有效支持数据库即代码工作流程。Liquibase 和 Flyway 等工具提供了用于管理数据库迁移和模式版本控制的框架。这些平台提供 database-agnostic（与数据库无关）的方法，可以跨多个数据库系统工作，同时保持一致的工作流程。
云平台和容器化技术也采用了数据库即代码原则，提供与版本控制系统和部署管道无缝集成的托管服务。这些工具减少了实施数据库即代码的运营开销，同时提供了企业级可靠性和可扩展性。
Navicat Premium 通过提供一系列工具，增强了“数据库即代码”的实践效果，这些工具能够促进基于代码的方法来管理及生成数据库架构和数据。Navicat 在几个重要方面支持“数据库即代码”的原则：
从可视化工具中生成 SQL
Navicat 的可视化查询创建工具、数据建模工具和存储过程创建工具允许用户以图形方式设计和管理数据库对象。然后，这些可视化操作被转换为相应的 SQL 脚本，这些脚本可以作为 DaC 工作流的一部分进行版本控制。
代码段和自动化
代码段功能允许用户保存和重复使用常见的 SQL 语句和代码块，从而提高一致性并减少手动编码。此外，还可以配置和安排批处理作业和自动同步数据等功能，从而实现符合 DaC 原则的自动化数据库任务。
数据迁移和同步
Navicat 提供了用于数据迁移和同步的简化向导，可用于以受控和可重复的方式管理数据更改，这是 DaC 的一个关键方面。这些操作生成的 SQL 脚本也可以合并到版本控制系统中。
SQL 编辑器功能
Navicat 中的 SQL 编辑器提供代码补全、语法高亮显示和 SQL 美化工具等功能，提高了手动编写的 SQL 代码的效率和质量。这为 DaC 创建干净且可维护的 SQL 脚本提供了支持。
数据建模和模式导出
Navicat Data Modeler 允许数据库模式的可视化设计，并将这些设计导出为 SQL 脚本。这提供了可以进行版本控制和部署的数据库结构的基于代码的表示形式。
结语
数据库即代码代表了基础设施即代码原则的自然演变，将数据库管理从一个容易出错的手动流程转变为支持现代开发工作流程的可靠、自动化系统。虽然对于拥有既定流程的组织来说，最初的过渡似乎具有挑战性，但提高一致性、可追溯性和协作的长期好处远远超过学习曲线。通过采用数据库即代码实践，组织可以将其数据库管理从容易出错的手动流程转变为支持现代开发工作流程和业务需求的可靠自动化系统。
