This course takes Java beginners to the next level by covering Object-oriented modelling allows for efficient construction of\ud multi-disciplinary system models in a physically-oriented way. UML - Unified Modeling Language utilizes text and graphic documents to enhance the analysis and design of software projects by allowing more cohesive relationships between objects. The approach Object-oriented techniques are used extensively for the development of applications in various fields [7,14,18]. An object can be defined as a data field that has unique attributes and behavior. However, an object encapsulatesboth data andbehavior, implying that we can use the object-oriented approach not only for data modeling, but also to model system behavior. The main difference between Object Oriented Database and Object Relational Database is that Object Oriented Database is a database that represents data in the form of objects like in Object Oriented Programming while Object Relational Database is a database that is based on the relational model and object-oriented database model.. A database allows storing and managing data easily. Figure 2-Object-oriented modelling approach allows rapid assembly of representative models Case study: object-oriented modelling approach for an option study The project in this case study is for a new underground platinum mine. OOP focuses on the objects that developers want to manipulate rather than the logic required to manipulate them. Benefits of Object-Oriented Approach . The operator has to always come in the middle of the statement. In the object-oriented design method, the system is viewed as a collection of objects (i.e., entities). Syllabus (GTU ... Association Classes The abstract class is a class that allows the association to be a class itself. A database of reusable components supplies the components for re-use.
