《Database和数据库打交道-2020红宝书词汇(必考词+基础词+超纲词)-连线自测本》是一本针对Go语言学习者编写的实用指南,特别关注于Go语言在数据库交互方面的知识。该书籍分为六个章节,涵盖了Go语言的基础概念、高级特性以及与数据库相关的技术。 第1章“语言基础”深入浅出地介绍了Go语言的基本构造,如创建Hello, World程序,数组、字符串和切片的使用,函数、方法和接口的定义,以及面向并发的内存模型,这些都是理解数据库操作的关键。章节中还涵盖了错误处理和异常管理,这对于编写稳定且健壮的数据库驱动程序至关重要。 第二章“CGO编程”着重于Go语言与C/C++交互的能力,包括快速入门、类型转换、函数调用等,并通过实战封装qsort来展示如何利用CGO进行底层操作。这部分内容对理解数据库连接池或直接操作数据库接口可能用到的C扩展至关重要。 第3章“汇编语言”部分让读者了解汇编语言的基础知识,包括计算机体系结构、控制流等,对于理解Go语言的底层执行机制和优化数据库查询性能有帮助。通过GoroutineID的例子,读者可以学习如何在低级别上管理和同步并发。 第4章“RPC和Protobuf”章节讲解了远程过程调用(RPC)的概念,以及如何通过Protocol Buffers (Protobuf)进行数据序列化和反序列化,这对于构建分布式系统中的数据库接口和服务间通信至关重要。GRPC的介绍则展示了Go语言在高性能RPC框架中的应用。 第5章“Go和Web”将数据库操作与Web开发结合,涵盖了路由、中间件、验证、数据库连接、流量控制、项目分层设计以及灰度发布等主题,这些都与后端数据库操作紧密相连。 最后的第6章“分布式系统”探讨了Go语言在分布式环境下的应用,涉及数据库在分布式架构中的角色,如何设计分布式数据库访问策略,以及如何实现负载均衡和故障恢复等关键知识点。 综上,这本书籍提供了一个全面的学习路径,不仅教授Go语言语法,还深入介绍了如何利用Go进行高效、安全的数据库交互,是任何想要在Go领域从事数据库开发者必备的参考资料。

请阅读下面文字并完成这个数据库的ER图 题目背景以及要求 SirenCD is a digital media company that runs several retail stores that sell CDs to customers. In this coursework, you are asked to design a database for SirenCD to help manage the information of artists, albums, media tracks, and media purchases. The final database must be in 3NF and have no M:N relationships. You will also be asked to write a few queries based on your database design. 数据库设计 The retail stores of SirenCD sell many different CD albums. An album can have one or more soundtracks. Each soundtrack has its track name, release date, genre, length and composer. Each album is associated with an artist. Customers can look up information about all artists, such as date of birth, biography and all his/her albums from the website of the company. The company provides a special service that allows customers to make their own CDs by providing a playlist to the company. These playlists can have tracks from different albums. The selection of soundtracks for these playlists are private to customers and are not visible to others. The price of such a customised CD is the sum of the prices of all soundtracks plus 30. Before being able to make purchases, a customer needs to register an account with the help of a retail store staff. The information needed for registration includes name, phone number, membership card number, address (for delivery, when needed) and the staff id who helped with the registration. The information about staff members consists of the staff id, name, the store he works in and the date of joining the store. After purchasing CDs, the customer will receive an invoice with the list of items he/she purchased. The information of invoices should also be stored in the database. You need to decide what to include in your database.
