昨夜到位了Web端新扩充图书消息的法力,以后就差DB的实际贯彻了。

首假诺参照豆瓣的书本查询接口:

因为笔者把Book相关的音讯拆分的可比多,所以更新有一点点小麻烦。

第风流洒脱,我索要创立七个Book Type的Matter;

归来内容如下:

下一场,将图片路线保存到FileBank中,并赶回FileBankID;

图片 1图片 2

此起彼伏,插入Publisher消息(必要判别name不设有才会insert),然后回到PublisherID;

He is founder and president of Object Mentor, Inc., a team of experienced consultants who mentor their clients worldwide in the fields of C++, Java, C#, Ruby, OO, Design Patterns, UML, Agile Methodologies, and eXtreme programming.", 
75     "summary": "Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.
76 Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of a software craftsman and make you a better programmer—but only if you work at it.
77 What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft.
78 Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code—of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code.
79 Readers will come away from this book understanding
80 How to tell the difference between good and bad code
81 How to write good code and how to transform bad code into good code
82 How to create good names, good functions, good objects, and good classes
83 How to format code for maximum readability
84 How to implement complete error handling without obscuring code logic
85 How to unit test and practice test-driven development
86 This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.",

豆瓣图书查询重返内容

 

 

三番五次,插入Binding消息(也急需看清name不设有才insert),再次回到BindingID;

刚才出去拿纱窗了,等清晨设计DB的时候继续纠正。
