Foreword: Writing this article three motivations: First, I have to vent my uneven - because I spend a lot of money to buy books, I will regret it, I want to give you an advice. - Or suggestion, after taking the bitterness, I don't want more people to have the same experience; the third, I want to ask some people, if they first published these books, I thought too More money! money! money!
The mystery is finally revealed! I am a happy heart! Although there is still a hit hesitation - do I really write this article? For a book you don't like? Is it worth spend so much "youth"? But I can't take much more - if I don't say it, maybe I will not be relieved in my life.
Title: "Delphi Database Programming Technology".
Publisher: People's Posts and Telecommunications Publishing Houses. Author: ...... [authors deleting four names]
I think everyone should have earned (or personal experience) on this publishing house. Summary, that is, when you think a book is good (set with a slogan: "Cheap is cheap, very good"), you look at its publisher, will never be this; When you find that a book is not very satisfactory, you look at its publisher, ten eight nine is this home - this is not a coincidence, because there is no such coincidence in the world - and has become A law. Therefore, when I later saw "People's Postal and Telecommunications Publishing House", I will no longer have any expectations - I hope how it makes me satisfied, but at this time, some parts of the body will be difficult for a while. ...

Price: RMB 43.00 yuan.
The reason why the so-called one penny is not affected here.
Content - Evaluation of a book of a book to be seen. Take a look, see what this book brings to us? I gave me at the time - a technique of a technique (Biginner) missed something.
"Foreword: This written reader to each level: from Delphi, the reader with a certain programming language can complete the study of Delphi through this book; for the support of Delphi, there is no database development experience, more Through this book learning, understand the essence of the development of the database, becoming a master of database development; for readers who already develop experience in Delphi database, you can also get some programming inspiration from this book, fully grasp Delphi's kernel, and enrich relevant knowledge , Complete the preparation of high quality code. "
Wow! "In summary, this book is suitable for you. No matter what you belong, buy this book is worth it!" This kind of beautiful words can really be 人! " Is it true? Let's take a look at its chapter arrangement. (Hey, there are so many tongues ... I still have to break it!)
The following chapters in the books are listed, with comments.
Chapter 1 Delphi Basics
Comment: For the overall introduction to Delphi, basically translate the new features section of the help file;
Chapter II Delphi Quick Start
Comments: Mainly introducing IDE, plugging a large number of screen graphics (including a startup screen of a Delphi 4) is really a suspicion for the exemption of the space. Chapter III Object Pascal Language Foundation
Comment: Named Object Pascal, but no word tells Object, there is no introduction to the object-oriented language characteristics. The specific content is not a non-data type (enumeration, sub-boundary, array), process and function, and more. The check help will know that - perhaps the author is to help translate, or turn it down - not known. The description of this chapter is clearly that the reader is positioned at the level of positioning. It is time to introduce for the process and function.
The fourth chapter programming with Delphi objects
Comment: This chapter refers to the three major characteristics of the class: package, inheritance, and polymorphism, and tells a section for exceptional processing. But the introduction to Object Pascal language features is too thin. The introduction of the "Object Pascal Program Code" section also seems to have some paintings of snakes - whether the unit's frame (INTEFACE, USE, IMPLEMENTITION, etc.) is worth spending so many levels?
Chapter 5 Database System Introduction
Chapter 6 Using Database Access Controls
Chapter 7 Using Data Browsing Controls
Chapter 8 Using the Delphi Database Accessories
Chapter 9 Report Production and Statistical Treatment
Chapter 10 SQL language usage and programming
The eleventh chapter further understands the data set control
Chapter 12 Delphi Customer / Service Application Development
Chapter 13 MIDAS Programming
The above chapters focus on the application of Delphi in the database. Because Delphi provides many database-related components - therefore, this book is inevitable to spend a lot of space in the use of database components - and this, often gives beginners a misleading - whether developing database applications Just use existing components? Is the essence of Delphi development lies in using existing VCL components?
The location of "SQL Language Use and Programming" is slightly rely on. I don't know if the author's original content is that the part is too difficult to put it behind?
The book is filled with the unclear source code - a large part from Delphi's Examples! The author takes them one by one by the name of the source code. If you don't ask if there is a suspect with piracy, these examples are quoted, I want a little scholastic reader, "Rehabilitation" should not be a problem.
Summary: It is the most fundamental reason for the reader's positioning is the most fundamental reason for the book "I don't like the book". Want to make your own books for readers of all walks of life, often leading to their books that cannot be accepted by readers of any class. It is not to be accepted that no one is purchased - when this book will be launched, the publishers are also bigger. Because there are many initiaters (such as me) - the author's flower saying - and generosity. One of them will be in today, write an article to express their dissatisfaction and regret - this is probably what those who are not expensive to start.
