The objective of this book is to enlighten you in the ways of DotNetNuke by showing you how to design and implement a professional, real-world DNN website solution, while taking the opportunity to outline and detail many of the terrific features of the DNN framework. While describing in detail how to take full advantage of just some of DNN's feature set, the book explains explain most of the problems you'll face when building your website, and offers one or more solutions for solving them. In the end, the result will be a great deal of knowledge surrounding a key set of features that includes a myriad of functions you may not have thought were possible from an open source application framework. Many beginning to intermediate users will be surprised, by the depth and power of DNN and the ease at which professional-level, modern functionality can be implemented. More advanced users may already be utilizing DNN in similar ways but should also find the information contained in this book to be helpful and insightful. This book is basically a large case study that starts with a foundation and works its way through to completion with a series of designs and solutions for each incremental step along the way. What sets the Problem-Design-Solution series apart from other Wrox series is the structure of the book and the start-to-finish approach to many aspects of a completed project. Specifically, this book leads the reader through the development of a complete modern, sophisticated, highly functional, and professional DNN business website solution including many of DNN's key built-in modules/functionality: Account login/registration, roles, and permissions Announcements FAQ Media Links Survey Text/HTML From an administrative point of view, the following features and problems are also covered: Full DNN Administration to manage many aspects of the website solution Skin deployment Content deployment The implementation of each of these features provides the opportunity to present various processes of creating, designing, and developing our DNN website solution such as the following: Skin and containers/site layout CSS customizations Security: site membership, roles, and profile management Detailed content implementation: working with pages and modules This book covers DNN's key built-in features and demonstrates how to get the most out of them to create a complete, professional website solution. All of the features are explained and presented in detail to make you aware of all of the options that are possible. At the end of the book you will have learned many of the best practices for using DNN and will have acquired a well-rounded foundation to use it comfortably on a day-to-day basis, allowing you to gain proficiency and efficiency in developing more professional and profitable DNN website solutions. This book provides the foundation to build a complete, professional DNN website solution based on a key set of built-in features. All chapters are self-contained components within the overall solution, build on the chapters before it, and are structured in three sections: Problem: This section defines the problem or problems to be addressed in the chapter: Which key DNN features should you take advantage of and why are these features important? What restrictions or other factors need to be taken into account? Design: After the problem is defined adequately, this section describes what features are needed to solve the problem. This will give you a broad idea of how the solution will work or how the solution to the problem will be accomplished. Solution: After preparing what is going to be accomplished and why (and how it solves the problem defined earlier), we will produce and discuss the code, page, and module configurations, and so on, and any other material that will realize the design and solve the problem laid out at the beginning of the chapter. Just as the coverage of this book as a whole is weighted toward solution, so is each chapter. This is where you will get hands-on practice and create the code. This book is intended to be read from cover to cover, so that you start from scratch and finish with a complete website solution. However, the book follows a modular structure, so every chapter is quite self-contained and implements DNN features that, if necessary, can be "turned on or off" at any time. This book is not for advanced programmers who use DNN at the core level to create modules or extend the project. This book is intended for beginning-to-intermediate users, as well as some advanced users, who want to learn: How to create a great-looking DNN website and how to customize it with CSS How to use DNN's built-in functions and modules to implement a complete professional, content-driven business website solution while providing the necessary core skills that will help you become proficient in your day-to-day usage of the framework While the book does not explain every last detail of the DNN technology, it does concentrate on functionality that is found “under the surface” while walking you through many processes and details that will allow you to take advantage of the DNN framework.

这本书最让我感到惊喜的是其对“遗留系统维护”这块内容的深入挖掘。在现实世界中,我们很少从零开始构建一切,更多的是在修补和迭代前人留下的代码库。作者非常现实地指出了在接手一个庞大而复杂的现有项目时,如何进行“手术刀式”的风险最小化干预。他提供了一套非常实用的诊断流程,包括如何快速定位性能瓶颈、如何安全地引入新功能而不破坏旧有逻辑,以及最关键的——如何与那些不愿改变的旧代码“和解”。书中提到的“渐进式重构”策略,简直是为所有维护老旧项目的工程师量身定制的良方。它教会我们如何用最小的代价,逐步优化那些看起来像“千年老妖”一样的代码结构,这比任何鼓吹“推倒重来”的书籍都要来得实用和宝贵。它真正做到了技术上的“授人以渔”,并教会你如何在泥泞中前行。
评分我个人对这本书中关于安全性和可扩展性部分的论述给予高度评价,这往往是很多初级教程会略过,或者一笔带过的地方。作者用一种近乎“预言家”的口吻,提前指出了未来网站在面对流量洪峰和安全威胁时可能遇到的瓶颈。例如,关于负载均衡策略的讨论,不仅仅是介绍了A/B两种方案的优劣,而是结合了不同行业(如媒体发布与实时交易)的具体需求,给出了量身定制的建议。当我读到关于缓存机制的深度剖析时,我简直惊呆了。它详细阐述了不同层级缓存(浏览器缓存、CDN缓存、应用层缓存)之间的协作与冲突管理,这种系统性的思维,让我对构建一个能“活得久”的健壮系统有了全新的认识。这本书让我明白,优秀的设计不在于功能多么花哨,而在于它在压力之下能否保持稳定和高效。
评分这本书的叙事节奏把握得相当老道,它懂得如何在一堆技术术语中穿插一些引人入胜的案例研究。我记得有一章专门分析了一个在用户体验上做得非常糟糕的电商网站,作者并没有简单地批判其设计缺陷,而是深入挖掘了导致这些缺陷的深层技术原因——比如前端渲染阻塞如何影响了用户的感知速度,或者数据库查询优化不当如何造成了关键节点的卡顿。这种从“现象”反推“本质”的分析路径,对我来说是极具启发性的。它让我意识到,一个“坏”的网站体验,往往不是单一因素造成的,而是一系列技术决策失误累积的结果。更妙的是,针对每一个被剖析的“病灶”,作者都提供了非常具有可操作性的“治疗方案”。读到这些解决方案时,我总忍不住想马上打开我的开发环境,去验证一下这些策略的有效性。这绝不是一本只停留在理论层面的书籍,它更像是一本实战手册,充满了实战的硝烟味和解决问题的快感。
评分从文风上来说,这本书的作者显然是一位经验丰富且略带幽默感的导师。他的语言风格非常接地气,不会让人觉得是在阅读晦涩的官方文档。在讲解那些枯燥的API调用细节时,他总能找到一个恰当的比喻来辅助理解。比如,他将“异步处理”比作餐厅后厨的点单系统,清晰地解释了为什么有些任务需要“等待”而有些可以“并行处理”。这种将复杂概念“日常化”的能力,极大地降低了学习的门槛和心理负担。我感觉自己不是在啃一本技术书,而是在一位资深前辈的午后茶叙中听他传授多年经验。这种亲切感,使得即便是涉及到一些比较前沿的框架特性时,我也能保持专注和好奇心,而不是望而却步。这种人情味的写作方式,使得这本书的阅读体验远超同类产品。
评分这本关于网站构建的读物,给我的感觉就像是拿到了一份详尽的建筑蓝图,只不过这次的主角是数字世界的门面。我尤其欣赏作者在探讨基础架构时那种近乎偏执的细致,对于那些初入门户的新手来说,那些关于服务器配置、数据库连接的讲解,简直就是救命稻草。它没有那种高高在上的理论说教,而是实实在在地告诉你:“看,当你遇到这个报错信息时,问题很可能出在那个配置文件里,试试这样做。” 这种手把手的指导,让原本复杂难懂的后端知识变得平易近人。它不仅仅是教你如何搭建一个网站,更是教你如何理解网站“活”起来背后的逻辑。书中的图表清晰明了,每一步操作都有明确的预期结果,这极大地减少了我在实际操作中走弯路的概率。读完这部分内容,我感觉自己对整个网站生命周期的掌控力提升了一个档次,不再是那个只会点点鼠标、上传文件的“小白”了,更像一个能深入地基考察的工程师。那种踏实感,是其他一些泛泛而谈的入门书籍所不能比拟的。
