Benefits of Object-Oriented Approach. Object-oriented databases make the promise of reduced maintenance, code reusability, real world modeling, and improved reliability and flexibility. However, these are just promises and in the real world some users find diswdvantages the object-oriented benefits are not as compelling as they originally believed.

Some will say that they can reuse much of the object-oriented code that is created for a system, but many say there is no more code reusability in disadvaantages systems than in traditional systems.

Code reusability is a subjective thing, and depends heavily on how the system is defined. The object-oriented approach does give the ability to reduce some of the major expenses associated with systems, such as maintenance and development of programming code. Disaxvantages are some of the benefits of the object-oriented approach: The primary goal of object-oriented development is the assurance that the system will enjoy a longer life while having far smaller maintenance costs.

Because most of the processes within the system are encapsulated, the behaviors may be reused and incorporated into disadvntages behaviors. Object-oriented system tend to model the real world in a more complete ooaf than do traditional methods.

Objects are organized into classes of objects, and objects are associated with behaviors. The model is based on objects, rather than on data and processing. Improved Reliability and Flexibility: Object-oriented system promise to be far more reliable than traditional systems, primarily because new behaviors can be “built” from existing objects.

Because objects can be dynamically called and accessed, new objects may be created at any time. The new objects may inherit data attributes from one, or many other objects. Behaviors may be inherited from super-classes, and novel behaviors may be disadvantagess without effecting existing systems functions.

When a new object is created, it will automatically inherit the data attributes and characteristics of the class from dissadvantages it was spawned. The new object will also inherit the data and behaviors from all superclasses in which it participates. When a user creates a new type of a widget, the new object behaves “wigitty”, while having new behaviors which are defined to the system.

Advantages and Disadvantages of Object-Oriented Approach

The downside of the Object Technology. Wide-scale object-oriented corporate systems are still unproved, and many bread-and-butter information systems applications i.

Object-oriented Development is not a technology – Although many advocates are religious in their fervor for object-oriented systems, remember that all the “HOOPLA” is directed at the object-oriented approach to problem solving, and not to any specific technology. Object-oriented Development is not yet completely accepted by major vendors – Object-oriented Development has gained some market respectability, and vendors have gone from catering to a “lunatic fringe” to a respected market.

Disadvantages of Object Oriented Analysis and Design

When one investigates the general acceptance of object-oriented systems in the commercial marketplace, you generally find that most managers would like to see an object technology approach, but they do not have the time to train their staffs in object-oriented methods. Other will say that the object-oriented method is only for graphical workstation systems, and that there is no pressing need for object-oriented system within mainstream business systems.

Once a major vendor begins conforming to a standard, it can become impossible to retrofit their standard to conform to another standard. When one strips away all of the confusing acronyms and jargon, the object technology approach is nothing more than a method, an approach to systems design which can be implemented without any changes to existing software technology.
