Introduction

This is a masterpiece purely discussing dlephi object-oriented programming.
This book aims to be proficient in Delphi Object-Oriented Programming and explains in depth the concepts and essence, methods and experiences, ideas and practices of Delphi object-oriented programming; it discusses in detail the advanced object-oriented skills that Delphi has built on dynamic binding mechanisms such as virtual methods, abstract methods, and object interfaces, as well as type conversion mechanisms such as upward transformation, downward transformation, and interface transformation; in addition, we have thoroughly studied how to separate interfaces from Business Objects through encapsulation, and gradually implemented a distributed multi-layer architecture from the interface and business separation, thereby implementing cross-platform enterprise-level solutions for interfaces and business applications. This book also provides VCL's internal information and research experience.
The book uses the modelmaker that comes with Delphi7 to implement ul-to-ul Object Modeling, along with a large number of Delphi source code instances for readers to study and learn. This book is applicable to software developers who have a certain degree of Delphi Foundation and want to master object-oriented programming ideas and methods to further improve the level. Similarly, Java and C ++ programmers who have mastered object-oriented programming can quickly master Delphi programming through this book.
This book is also suitable for colleges and universities to teach Object-Oriented Programming Based on Object Pascal/Delphi. All rights reserved. infringement is required.
"Selecting object-oriented programming means you need to discard some visual programming methods ."
--- Marcocantu
"Using object-oriented tools in non-object-oriented methods is an error. Using Delphi to write structured programs can quickly reach Beta ...... Your program may never be released from Beta. It is still wrong to quickly get the wrong answer ."
--- Paul Kimmel
"Remember, successful developers only need to write a small amount of high-quality code, rather than a large amount of common code ."
--- Grady booch
Main content of this book:
● Introduction to object-oriented programming and the Object Model of Delphi.
● Understand the essence of Delphi objects and use the skills of Delphi objects.
● Analysis of concepts such as polymorphism, interfaces, virtual methods, and abstract classes and specific application of object-oriented programming.
● Advanced object-oriented programming skills based on dynamic binding and type conversion mechanisms.
● In order to realize the maintainability, scalability and reusability of the program, an in-depth discussion of encapsulation, interface and Business Object separation, distributed multi-layer architecture, and implementation interface and business application cross-platform is given.
● VCL's internal information and research experience.
