In this comprehensive guide to creating an e-commerce Web site using PHP and mysql, renowned author Larry Ullman walks you through every step--designing the visual interface, creating the database, presenting content, generating an online catalog, managing the shopping cart, handling the order and the payment process, and fulfilling the order--always with security and best practices emphasized along the way. Even if you're an experienced Web developer, you're guaranteed to learn something new. The book uses two e-commerce site examples--one based on selling physical products that require shipping and delayed payment, and another that sells non-physical products to be purchased and delivered instantly--so you see the widest possible range of e-commerce scenarios. In 11 engaging, easy-to-follow chapters, Effortless E-Commerce with PHP and mysql teaches you how to: / Think of the customer first, in order to maximize sales / Create a safe server environment and database / Use secure transactions and prevent common vulnerabilities / Incorporate different payment gateways / Design scalable sites that are easy to maintain / Build administrative interfaces / Extend both examples to match the needs of your own sites Larry Ullman is the president of Digital Media and Communications Insights, Inc., a firm specializing in information technology (***). He is the author of several bestselling programming and Web development books, including PHP and mysql for Dynamic Web Sites: Visual QuickPro Guide. Larry also writes articles on these subjects and teaches them in small and large group settings. Despite working with computers, programming languages, databases, and such since the early 1980s, Larry still claims he's not a computer geek (but he admits he can speak their language).

mysql是一种关系型数据库系统,相比较其他数据库系统而言,mysql是目前运行速度最快的数据库系统之一。其优势在于源代码开放,任何人都可以依据General Public License,下载并根据个性化的需求对源代码进行修改。插件式存储引擎是mysql数据库系统最显著的特色之一,作为数据库服务器中的组件,它负责为数据库执行数据I/O操作,解决了关系型数据库物理层优化这个难题。数据库专业人员可根据数据读取模式的特定需求,来选择专门的存储引擎。不同的存储引擎具有不同的能力,应用程序是与之分离的。
本文针对mysql源代码展开研究,深入分析mysql内核的设计与实现。论文首先介绍关系型数据库基础知识以及mysql数据库系统总体架构。然后研究mysql内核的实现方法,分析代码的核心类和核心算法,重点剖析插件式存储引擎体系结构,介绍两种经典存储引擎:MyISAM和InnoDB。最后开发设计出自定义存储引擎Nanjupt,引擎能够实现表操作、数据操作及索引功能。
