Entity Relationship Diagram Examples

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ConceptDraw gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

UML Deployment Diagram

UML Deployment Diagram depicts the physical deployment of artifacts on nodes (nodes are the existing hardware components, artifacts are the software components running on each node); and how the different pieces are connected.
Use ConceptDraw DIAGRAM with UML deployment diagram templates, samples and stencil library from Rapid UML solution to model the physical deployment of artifacts on nodes of your software system.

Use Case Diagrams technology with ConceptDraw DIAGRAM

Use case diagrams are used at the development of software and systems for definition of functional system requirements or system of systems. Use case diagram presents the consecution of object’s actions (user’s or system’s) which are executed for reaching the definite result.
