A static uml object diagram is an instance of a class diagram. Uml is a way of visualizing a software program using a collection of diagrams. This helps to depict processes, architectures and systems in a pictorial method for better retention and understandability. A uml object diagram represents a specific instance of a class diagram at a certain moment in time. Unified modeling language is a language which is standardized and it uses specific symbols.
When represented visually, youll see many similarities to the class diagram an object diagram focuses on the attributes of a set of objects and how those objects relate to each other. Object is an instance of a particular moment in runtime, including objects and data values. Objects and links are the two elements used to construct an object diagram. It offers rich models that describe the working of any software hardware systems. The link in object diagram is used to connect objects. It is the most widely used uml diagram subcategory. There are many tools available in the market for designing uml diagrams.
After this, the following things are to be decided before starting the construction of the diagram. These come with easytouse software diagrams design tools with. Object diagrams are vital to portray and understand functional requirements of a system. The concept of jetuml is to provide the basic support for sketching software design ideas. In other words, an object diagram in the unified modeling language uml, is a diagram that shows a complete or partial view of the structure of a modeled system at a specific time. The class diagram is the building block of all object oriented software systems. Jetuml currently supports the following uml diagrams. It is a standard which is mainly used for creating object oriented, meaningful documentation models for any software system present in the real world. It may be considered a special case of a class diagram or a communication diagram. The notation has evolved from the work of grady booch, james rumbaugh, ivar jacobson, and the rational software corporation to be used for object oriented design, but it has since been extended to cover a wider variety of software engineering projects. Jetuml is a simple desktop open source unified modeling language uml tool uml diagramming. What does a simple name in uml class and objects consist of.
The object diagram should have a meaningful name to indicate its purpose. Edit object diagrams online to customize them to match your need and export them or share them with your team. Users can depict the static structure and identify classes relationship of a system by checking systems classes and attributes. Uml diagram everything you need to know about uml diagrams.
