UML Use Case Diagram Example. Social Networking Sites Project

UML Diagrams Social Networking Sites Project. 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 Facebook Socio-health system and is used at the projection and creating of the social networking sites.

UML Diagram of Parking

This sample shows the Use Case Diagram of parking lot control system. On this sample you can see use cases represented as ovals and three actors represented as figures of persons that employ these use cases. Associations between actors and use cases are shown as lines.
UML Diagram of Parking - This diagram can be used for understanding the process of working the car parking, at the projection and construction the parking by building companies and for automation the existing parkings.

An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

How to Create an Entity-Relationship Diagram Using ERD Solution

An entity-relationship diagram (ERD)is used in a database modeling process. ERD diagram shows a graphical representation of objects or concepts within an information system and their relationships. The ability to describe a database using the Entity-Relationship model is delivered by the ConceptDraw ERD solution.
