MySQL示例数据库(MySQL Sample Databases) 之 sakila数据库
官方示例数据介绍
MySQL 官方提供了多个示例数据库，在MySQL的学习、开发和实践中具有非常重要的作用，能够帮助初学者更好地理解和应用MySQL的各种功能和特性。
官方示例数据具体列表如下：
1. employee data (large dataset, includes data and test/verification suite)2. world database3. world_x database4. sakila database5. airportdb database (large dataset, intended for MySQL on OCI and HeatWave)6. menagerie database这些数据库都可以通过如下官方网址进行下载和安装

sakila数据库
可以在MySQL官方网站的示例数据库中(Sample Databases)找到Sakila示例数据库。Sakila示例数据库是由Oracle提供的，旨在替代原有的world示例数据库。相比于world示例数据库，Sakila示例数据库更加复杂，用于模拟一个DVD租赁店，并且包含了更多表格以及更复杂的表格关系。Sakila示例数据库被设计用来提供一个更加实用和有趣的示例，供MySQL学习者训练他们的SQL技能。如果您想要练习SQL技能，可以下载Sakila示例数据库进行尝试。
Sakila数据库包括16个表、7个视图、3个 Stored Procedures、3个 Stored Functions、6个触发器。
Sakila示例数据库中的基本表和视图简要介绍如下：1. actor - 这张表存储了所有演员的信息，包括演员的ID、姓名和最后更新时间。2. actor_info - 这个视图结合了 actor、film_actor 和 film 表，提供了更详细的演员信息，包括演员所出演的电影名称和描述。3. address - 这张表存储了客户的地址信息，包括地址ID、地址、区域、城市、邮编、国家和最后更新日期。4. category - 这张表存储了所有电影的分类信息，包括分类ID 和分类名称。5. city - 这张表存储了城市的信息，包括城市ID、城市名称、区域以及最后更新时间。6. country - 这张表存储了国家的信息，包括国家ID、国家名称以及最后更新时间。7. customer - 这张表存储了客户信息，包括客户ID、姓名、电子邮件、地址、区域、城市、邮编以及最后更新时间。8. customer_list - 这个视图结合了 customer、address 和 city 表，提供了更详细的客户信息，包括客户ID、姓名、电子邮件、地址、区域、城市、邮编、国家和最后更新日期。9. film - 这张表存储了所有电影的信息，包括电影ID、电影名称、描述、发布年份、语言ID、原始语言ID、时长、租赁持续时间、租赁费用以及最后更新时间。10. film_actor - 这张表存储了电影演员的关联信息，包括电影ID、演员ID以及最后更新时间。11. film_category - 这张表存储了电影类型的关联信息，包括电影ID、分类ID以及最后更新时间。12. film_list - 这个视图结合了 film 和 category 表，提供了更详细的电影信息，包括电影ID、电影名称、描述、发布年份、语言、分类、时长、租赁持续时间以及租赁费用。13. film_text - 这张表存储了电影的描述信息，包括电影ID、标题、描述以及最后更新时间。14. inventory - 这张表存储了所有电影的库存信息，包括库存ID、电影ID、租赁商店ID以及最后更新时间。15. language - 这张表存储了语言的信息，包括语言ID、语言名称以及最后更新时间。16. nicer_but_slower_film_list - 这个视图结合了 film_list、film_actor、actor 和 category 表，提供更详细的电影信息，包括电影ID、电影名称、描述、发布年份、语言、租赁持续时间、租赁费用、演员列表、分类列表以及平均评分。17. payment - 这张表存储了所有顾客的付款信息，包括付款ID、顾客ID、租赁ID、付款金额、付款时间以及最后更新时间。18. rental - 这张表存储了所有出租信息，包括租赁ID、客户ID、库存ID、租赁时间、返还时间、出租费用以及最后更新时间。19. sales_by_film_category - 这个视图统计了每种电影类型的销售额，包括分类名称、销售额以及最后更新时间。20. sales_by_store - 这个视图统计了每个店铺的销售额，包括店铺ID、城市、国家、销售额以及最后更新时间。21. staff - 这张表存储了员工的信息，包括员工ID、姓名、电子邮件、店铺ID、用户名、密码以及最后更新时间。22. staff_list - 这个视图结合了 staff 和 address 表，提供了更详细的员工信息，包括员工ID、姓名、电子邮件、地址、区域、城市、邮编、国家以及最后更新时间。23. store - 这张表存储了店铺的信息，包括店铺ID、地址ID、经理ID以及最后更新时间。Sakila数据库提供了丰富的数据集来演示如何使用MySQL进行高效的数据库查询和数据管理。通过使用Sakila数据库，初学者可以学习如何使用SELECT、JOIN、GROUP BY等关键字进行复杂的查询，使用INSERT、UPDATE、DELETE等关键字进行数据管理，以及使用约束、索引、存储过程等高级功能进行数据库设计和优化。
Sakila数据库还提供了一个典型的电影租赁业务场景，可以让学习者更好地理解数据库如何应用在真实的业务场景中。在官方网站上，有关该数据库的文档和示例都可以免费下载和使用。
