The Object-Oriented Thought Process

Objects with the Intent to Cooperate Designing with Reuse in Mind Designing with Extensibility in Mind Making Names Descriptive Abstracting Out Nonportable Code Providing a Way to Copy and Compare Objects Keeping the Scope as Small as Possible A Class Should Be Responsible for Itself Designing with Maintainability in Mind Using Iteration in the Development Process Testing the Interface Using Object Persistence Serializing and Marshaling Objects 6 Designing with Objects Design Guidelines Performing the Proper Analysis Developing a Statement of Work Gathering the Requirements Developing a Prototype of the User Interface Identifying the Classes Determining the Responsibilities of Each Class Determining How the Classes Collaborate with Each Other Creating a Class Model to Describe the System Prototyping the User Interface Object Wrappers Structured Code Wrapping Structured Code Wrapping Nonportable Code Wrapping Existing Classes 7 Mastering Inheritance and Composition Reusing Objects Inheritance Generalization and Specialization Design Decisions Composition Representing Composition with UML Why Encapsulation Is Fundamental to OO How Inheritance Weakens Encapsulation A Detailed Example of Polymorphism Object Responsibility Abstract Classes, Virtual Methods, and Protocols 8 Frameworks and Reuse: Designing with Interfaces and Abstract Classes Code: To Reuse or Not to Reuse? What Is a Framework? What Is a Contract? Abstract Classes Interfaces Tying It All Together The Compiler Proof Making a Contract System Plug-in Points An E-Business Example An E-Business Problem The Non-Reuse Approach An E-Business Solution The UML Object Model 9 Building Objects and Object-Oriented Design Composition Relationships Building in Phases Types of Composition Aggregations Associations Using Associations and Aggregations Together Avoiding Dependencies Cardinality Multiple Object Associations Optional Associations Tying It All Together: An Example 10 Creating Object Models What Is UML? The Structure of a Class Diagram Attributes and Methods Attributes Methods Access Designations Inheritance Interfaces Composition Aggregations Associations Cardinality 11 Objects and Portable Data: XML and JSON Portable Data The Extensible Markup Language (XML) XML Versus HTML XML and Object-Oriented Languages Sharing Data Between Two Companies Validating the Document with the Document Type Definition (DTD) Integrating the DTD into the XML Document Using Cascading Style Sheets JavaScript Object Notation (JSON) 12 Persistent Objects: Serialization, Marshaling, and Relational Databases Persistent Objects Basics Saving the Object to a Flat File Serializing a File Implementation and Interface Revisited What About the Methods? Using XML in the Serialization Process Writing to a Relational Database Accessing a Relational Database 13 Objects in Web Services, Mobile Apps, and Hybrids Evolution of Distributed Computing Object-Based Scripting Languages A JavaScript Validation Example Objects in a Web Page JavaScript Objects Web Page Controls Sound Players Movie Player Flash Distributed Objects and the Enterprise The Common Object Request Broker Architecture (CORBA) Web Services Definition Web Services Code Representational State Transfer (ReST) 14 Objects and Client/Server Applications Client/Server Approaches Proprietary Approach Serialized Object Code Client Code Server Code Running the Proprietary Client/Server Example Nonproprietary Approach Object Definition Code Client Code Server Code Running the Nonproprietary Client/Server Example 15 Design Patterns Why Design Patterns? Smalltalk's Model/View/Controller Types of Design Patterns Creational Patterns Structural Patterns Behavioral Patterns Antipatterns
