UML Use Case Diagram Example. Registration System
The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.
The essence of this diagram is as follows: the designed system is represented as a set of actors interacting with the system using the so-called “use cases”. In this case, an actor (acting person, actant, artist) is any object, subject, or system that interacts with a simulated system from the outside. In turn, the “use case” is a specification of the services (functions) that the system provides to the actor. In other words, each “use case” defines a certain set of actions performed by the system when interacting with an actor. At the same time, the model does not reflect in any way how this set of actions will be implemented.
In the structural approach, the analogue of the use case diagram is IDEF0 and DFD diagrams, use-work options (IDEF0) and processes (DFD), and actors — external entities (DFD).
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.

If you ever tried programming, you could face a lot of problems as a beginner. To help yourself, create a flowchart to follow an algorithm logic. Flowchart represents a program as a sequence of steps depicted in special symbols for each type of action.
This image of the interactive diagram made in ConceptDraw DIAGRAM applying the Live Objects technology. The diagram shows the effect of Selection Sort algorithm. The left part of the chart is the input area. The diagram in the central part of the drawing is a flow chart showing of the selection sort algorithm. The flowchart includes basic flowchart symbols, that represent various stages of algorithm. The flowchart symbols are connected with arrows ended lines, that depict the direction of the process flow. On the right side — the result is displayed.

Describing the way data flows through an information system might become a subject of a study. One of the kinds on a data flow diagram is called Gane Sarson Diagram after its authors, and it slightly differs from other notations. Process symbols in this notation are depicted as rounded rectangles connected with arrows representing data flows.
This is a sample of data flow diagram. It demonstrates utilization of the Gane-Sarson notation for making DFD on the example of an online appointment system of the Health Centre. This sample is used the vector objects library of Gane-Sarson DFD notation supplied by the ConceptDraw solution for data flow diagramming. It contains all symbols of the Gane-Sarson notation including connectors, jumps, and processes. This solution can be successfully utilized to generate DFDs for business documentation, and presentations.

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.

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.
