ConceptDraw DIAGRAM ER Diagram Tool
ER-diagram is a tool used for database modeling which allows to determine data and relationships among the data. These diagrams help to detail data storages and to document all the properties of designed system. ER-diagram contains entities, attributes of the entities and the relationships between them. Chen’s notation and Crow’s foot notation are commonly used to represent elements in ER-model. To create such diagram you should use specific software, such as Entity-Relationship Diagram solution for ConceptDraw DIAGRAM.ConceptDraw ER Diagram Tool works across any platform, meaning you never have to worry about compatibility again. ConceptDraw DIAGRAM allows you to make Entity-Relationship Diagram (ERD) on PC or macOS operating systems.
Example of DFD for Online Store (Data Flow Diagram) DFD Example
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams
Crow's Foot notation was proposed by Gordon Everest. According to this notation, the entity is represented by rectangle, relation is depicted by line which ties two entities involved in a relationship. Entity-relationship diagrams based on both Chen's and Crow's Foot notations, can be easily drawn using the ConceptDraw DIAGRAM ERD diagrams software tools for design element Crow's Foot and Chen from Entity-Relationship Diagram (ERD) solution.![How to Build an Entity Relationship Diagram (ERD)](https://i1.ytimg.com/vi/MA_cEfa3ucU/hqdefault.jpg)
Components of ER Diagram
ConceptDraw gives the ability to draw ER diagram (ERD) for visual describing database using the entity relationship symbols, work flow shapes, entity relationship stencils. Entity-Relationship model making possibility to describe a database using the components of ER Diagram in which in the tables data can be the point to data in other tables - for instance, your entry in the database could point to several entries.Entity-Relationship Diagram (ERD) with ConceptDraw DIAGRAM
Entity-Relationship Diagram (ERD) serves for detailed description of structures and databases. An ERD represents a diagram made up mainly of rectangular blocks (for entities, or data) linked with relationships. The links between the blocks describe relations between these entities. There are three types of relationships: one-to-one,one-to-many, many-to-many.
Draw Entity-Relationship Diagrams (ERD) easily with ConceptDraw extended with Entity-Relationship Diagram (ERD) Solution from the Software Development Area. Use ERD software to create ER diagram.

SDL Diagram
Specification and Description Language (SDL) is used for creating the object-oriented diagrams, visualizing the processes of the state machines for the systems of communication, telecommunication, automotive, aviation and medical industries. SDL is a specification language for creating specifications, descriptions of the behavior, data, and inheritance for real-time systems.This sample shows the SDL Diagram of the process game.
UML Collaboration Diagram (UML2.0)
UML Collaboration Diagram depicts the interactions between objects or parts in terms of sequenced messages and describes both the static structure and dynamic behavior of a system.Rapid UML solution provides templates, examples and libraries of stencils for quick and easy drawing all the types of system and software engineering diagrams according to UML 2.4 and 1.2 notations.

Notation & Symbols for ERD
The ER diagram is constructed from the specific ERD graphic elements. There are used 2 types of ERD notations: Chen and Crow's Foot.A complete set of work flow shapes, notation & symbols for ERD, entity relationship stencils, included in Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software, makes drawing diagrams based on ERD notation as smooth as possible.
UML Deployment Diagram. Design Elements
UML Deployment diagram describes the hardware used in system implementations and the execution environments and artifacts deployed on the hardware.ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML Deployment library.
Design Element: Crows Foot for Entity Relationship Diagram - ERD
