Object oriented file system design

Thus the players need to play the game within the defined rules. So the more the player knows those rules the better they can play the game without making fouls. Similarly, the rules for the object-oriented concepts are inheritance, composition, abstraction, encapsulation.

Thus the better we know these concepts the better design we can make. Let's say you want to design an online shopping web Application like amazon. So before making that web application you have to think of :.

Now once you finalized all these things and went to implement writing code any part of the system then you can follow the Object-oriented design to make classes, interfaces etc. For example, you started implementing the notification microservice say in Java , so now you have to design classes, interfaces etc.

So we can say that object-oriented design is a part of system design which comes into picture when we start working on the actual implementation for any part of the system. System in System Theory can be everything. In overall, System Development included 2 major phases :. These items related to specific methodology in system theory. As I said, System can be everything.

Each category may have detailed and specific analysis and design steps based on mentioned 2 major phases. In computer world, Software Systems is one of System categories. Each software Analysis and Design method is based on mentioned 2 major phases too.

Each of them has it's own Analysis and Design Steps. These steps are based on 2 major phases as well. But in details, they have some differences. To sum up, Systems Analysis and Design is a big picture to all other type of systems.

Learning System Analysis and Design helps to understand all other systems analysis and design and specially helps to compare and evaluate them. Objects are parts of a system. You can design a system in high level with overview or in low level with details. Branches Tags. Could not load branches. Could not load tags. Latest commit. Git stats 17 commits.
