UML Use Case Diagram. Design Elements
UML Use Case Diagram is a type of Behavior Diagrams that displays the dependencies between the actors and use cases.
UML Use Case Diagram displays the system on the conceptual level.
The purpose of a UML Use Case Diagram is to demonstrate the various types of users of a system and the different ways of their interacting with this system. Use Case Diagrams are often used together with the textual use cases and other types of diagrams.
The notation for a Use Case Diagram involves the following types of symbols:
- Use cases are represented as the horizontally shaped ovals and display the different uses.
- Actors are the people that employ the use cases and are represented on the diagram as figures of persons. Actors cannot be related each to other (except relations of generalization/inheritance).
- Associations are shown as lines between actors and use cases.
- System boundary – the box with the name and ovals (use cases) inside that sets a system scope to use cases.
- Packages that allow you to add the elements in groups.
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.
To design a Use Case Diagram use the UML Use Case Diagram library.
UML Use Case Diagram library contains 26 shapes:
- Include relationship
- Use case
- Communicates relationship
- Actor 1
- Uses relationship
- Extend relationship
- Generalization relationship
- Multiplicity: mandatory
- Package
- Multiplicity: many (zero or more)
- Communication line
- Use case set 2.0
- Divider
- Actor 2
- System boundary
- Frame, fragment
- Note
- Symbol << >>
- Association Many-to-Many
- Association One-to-Many
- Smart connector (with options)

To maintain big and complex mechanical systems, you need an appropriate education and tools. It’s needless to say that mechanical drawing is important part of any industrial project. There are a lot of standard symbols depicting valves, pumps, motors, etc.
This drawing illustrates the content of the Fluid Power Equipment library provided by the ConceptDraw Mechanical Engineering solution. The solution is composed from the 8 libraries, containing about 500 elements related to mechanical engineering visualization. it will be helpful for drawing various schemes, charts and blueprints of pneumatic, and hydraulic equipment or other drawing related mechanical engineering. All drawings can be freely resized without loss of quality due to the vector graphics components of its facilities.

Business Process Modeling Notation -BPMN- is a set of standard symbols that allow you to create a graphical view of a business process. The symbols were developed to help users develop standard, unified structure of processes, and any messages shared between these processes. This is business process improvement tools.

Database design is an important part of any project, as databases become more and more complex nowadays. To make the model more representative, entity relationship diagrams are widely used in software engineering area. These diagrams show sets of entities as rectangles connected via lines labeled with their cardinalities.
This an example of the ER-diagram developed to store information regarding some online role-playing game. It includes three main elements of ER diagram: entities, relationships and attributes. The entities, attributes and relationships on this ER-diagram is depicted according to the Chen's notation. Chen's notation for Entity Relationship diagrams admits using of rectangles to depict entities, ovals for attributes and ,at least, diamonds to show relationships. ConceptDraw Entity-Relationship Diagrams solution was applied as ERD software to create this diagram.

Data processing can be very complex sometimes. If you are interested in facilitating your work with data, it’s time to learn how to draw flowcharts with special software or using just a piece of paper. The list of flowchart basic symbols includes rectangles, diamond, ellipses etc. and is used to represent processes, actions, decisions or data processing.
A well-done flowchart bring the clearness of the sequence of a process stages. There are number of symbols that can be used in flow charts to show various sorts of steps. The basic flowchart can be created using a few of them: Process, Decision, Start/Finish. A basic element of a flowchart represents a simple action and looks like a box, that contains a description of the action. The depicting of actions sequence is made with arrows between corresponding action boxes, as you can see on the sample diagram. Also it shows the symbols for flowchart start and finish steps. ConceptDraw Flowcharts solution provides the ability to build basic flow charts as well as the ones of any size and complexity with a minimum of actions.

Visual information is easier to perceive. You can teach even a child to make diagrams with a good flowchart example that would be interesting for it. Flowcharts can be fun, it’s not about business processes or programming algorithms.
This flowchart shows step by step process of manufacturing of Nixtamal The product which is obtained by processing maize with calcium hydroxide. We must assume that the Aztecs were very fond of this product, if the recipe of its production came to our times. This flow chart was designed using ConceptDraw DIAGRAM with its solution for designing flowcharts of various types, sizes and purposes. ConceptDraw Flowcharts solution consists from the library of flowchart symbols, containing the set vector objects. Also there are a lot of diverse templates and samples of flow charts.
