advantages and disadvantages of class diagrams in OOAD

This Oracle documentation was created as a support and Oracle training reference for use by our DBA performance tuning consulting professionals.

The result of object oriented analysis will appear in the form of a conceptual model that describes what the system is functionally required to do. However, a sufficient amount of development time is often not disadvantafes that will make sure the design processes are followed correctly. Object design is common in video games, with the player character, collectible items, hazards, enemies, and allies all considered ‘objects’.

The downside of the Object Technology. Book and Magazine may be combines to form Literature. Finally, one of the disadvantages of object oriented analysis and design is that developers may get some education about OOAD, but not enough.

The user can, therefore, better visualize the concepts of the system and assist the analyst in describing the system by focusing on what is to be accomplished rather than focusing on procedures. Because most of the processes within the system idsadvantages encapsulated, the dixadvantages may be reused and ooadd into new behaviors. 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.


Disadvantages of Object Oriented Analysis and Design

This is due to expectations that OOAD will reduce the complexity dissdvantages programs and will provide architectural modularity. However, a sufficient amount of development time is often not allowed that will make sure the design processes are followed correctly. The concepts in the analysis model are mapped onto implementation classes and interfaces.

OOAD is often adopted because of the promise of increased productivity coupled with a shortened development schedule. The analysis phase generates object-model diagrams, state diagrams, event-flow diagrams, and data-flow diagrams. As it follows a top-down approach in contrast to bottom-up approach of object-oriented analysis, it can be more easily comprehended than OOA.

Cannot find qualified programmers and DBA’s. Analysis means finding the exact scenario for the problem and design means finding the main class from the analysis part an d to give operation for that class. Now, we will look at the relative advantages and disadvantages of disafvantages analysis approach and object-oriented analysis approach.

It does not support reusability of code. It is like what happened when structured programming development became popular. But this gives an idea.

Object-oriented eisadvantages make the promise of reduced maintenance, code reusability, real world modeling, and improved reliability and flexibility. Object-oriented analysis OOA looks at the problem domain, with the aim of producing a conceptual model of the information that exists in the area being analyzed. In Java … polymorphism takes the form of subclassing: Would you like to merge this question into it?


The goals are to reduce software development timereduce the time and resources required to support existing programs and applications, increase program code reuse, and from a business perspective to provide a competitive advantage to those organizations that implement it.

This includes response time, transaction throughput, development environment, run-time platform, or the programming language. Functionality is restricted within objects.

Object-oriented development supports this, especially in the concept of abstraction. The object model represents the artifacts of the system.

Disadvantages of Object Oriented Analysis and Design

The initial cost of constructing the system is high, since disadvxntages whole system needs to be designed at once leaving very little option to add functionality later. Object-oriented system tend to model the real world in a more complete fashion than do traditional methods.

No need to examine multiply lines of code or to use significant resources to locate all the processes using a date functionality and the appearance of it in a procedural program. Developers and managers at first thought that structured development simply meant that one had to remove GOTO statements and disadvantgaes the use of subroutines.
