Object-oriented design is a software design that replaces linear code with code that adapts to specific objects. It has driven the development of technologies like Microsoft Visual Basic and C Suite. Each object may contain its own code, and programmers can separate them into classes. Sequence diagrams can be useful in object-oriented design. It is a versatile form of code that will continue to drive technological advances in software design.
Object-oriented design (OOD) is a special type of software design developed to replace simple linear code with a type of code that adheres to more complex conventions. In object-oriented design, code refers to a specific “object” and conceptually “adapts” to that object to provide specific user operations or other conditions. Object-oriented design is also called object-oriented programming (OOP).
Object-oriented design has driven the development of many new technologies including those related to Microsoft Visual Basic and the C Suite (C, C++, C#) of programming languages that are still widely used today. As a conceptual model for better software code conventions, object-oriented programming is perfect for the kind of visual applications often built in Visual Basic that are commonly used in Windows operating systems. Object-oriented analysis can also provide a better way of looking at the “raw code” to understand what is at work in a specific program or application.
An example of object-oriented design involves the various buttons, text boxes, image boxes, etc. which are programmed into visual applications. Each of these “objects” may contain its own specific code that governs the behavior or use of that object. Programmers can further separate various instances of an object into “classes” upon which functions or other modules of code can be used.
In object-oriented design, a sequence diagram of the system can be useful. These diagrams operate according to a Unified Modeling Language. A system sequence diagram (SSD) shows various events driven by “actors” that help define the behaviors and uses of objects in a program.
As a more versatile form of code than older linear systems developed with primitive software such as BASIC and FORTRAN, object-oriented programming is likely to continue to drive technological advances in software design. Along with coding languages like XML and other markup languages, object-oriented programming can drive both highly conceptual and highly functional programs. This type of software design contributes to a philosophy of creating virtual objects that will serve the IT community well in efforts to isolate and enhance various software functions, or shape software to mimic events in the physical world. Meanwhile, object-oriented programming has become a universally useful standard convention in the computer programming community.
