UML Object Diagram. Design Elements
UML Object Diagram is a type of Structure Diagrams that shows the objects of the system and attributes, and relations between the objects at a certain moment of time.
UML Object Diagram represents a specific instance of a Class Diagram at a moment of time.
A correlated group of the Object Diagrams shows how the system will develop over the time.
Objects and links on the UML Object Diagram are represented by Instance Specification that use the slots to show the object classifier, instance name, attributes and other structural characteristics. One attribute or feature has the one corresponded slot. Links between instances are named as links. You can also use the associations of aggregation (represents as empty diamond) or composition (represents as filled diamond), and other UML entities on the UML Object Diagram.
The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.

NINE RELATED HOW TO's:
While designing a conceptual data model, you should use appropriate software. For instance, ConceptDraw DIAGRAM is a user-friendly ER diagram tool that has a lot of samples and templates to facilitate your work. A clear entity-relationship diagram helps to define the relations between system’s components.
Software engineering is the section of a computer science engaged to design, realization, and support of complex software products. An ERD is a data modeling method that is widely applied in the software engineering practice. Commonly it is used for developing a structure of a a relational database. An entity relationship diagram is helpful for structuring and organizing databases that can be modeled using a relational structure. An entity relationship diagram is designed to depicts the interrelationships within the sets of entities which are accumulated in the database. Each entity represents a particular component of a data. Thus, ER diagrams depicts the logical structure of databases. ConceptDraw ER Diagrams solution provides software engineers with the professional tool for making entity-relationship diagrams.

You can use many tools to create a representation of a system behavior or a scheme of objects relationships. Some of them are quite abstract and useless, and some, like UML tools help clarifying both the structure and the behavior of a system. There are various types of uml diagrams and tons of examples explaining the difference between them.
UML 2.2 specification has many kinds of diagrams. They are divided into two groups( structure and behavior diagrams). This class diagram shows the hierarchical structure of UML 2.2 specification. Class diagram - the most suitable tool for this task because it is designed to describe basic structure of a system. This diagram can be use as a visual aid for learning UML.
