Design Element: Crows Foot
for Entity Relationship Diagram - ERD
Entity-relationship Diagram (ERD) is a perfect tool which lets execute the detalization of data warehouse for designed system, as well as documenting the entities of the system and their interactions each other, including the identification of important domain objects (entities), the properties of these objects (attributes) and their relationships to other objects.
Creating an ERD requires choosing a specific set of notations that best serve the specific database being designed. Chen’s original notation had a linguistic approach, where boxes representing entities could be thought of as nouns, and the relationships between them were in verb form, shown on a diagram as a diamond.
Eventually Chen’s style was adapted into the Crow’s Foot notation, where relationships were shown as single labeled lines – this quickly became the popular standard, due to improved readability on diagrams, with a more efficient use of space on the page.
ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons.

The samples you see on this page were created in ConceptDraw DIAGRAM software using the Entity-Relationship Diagram (ERD) solution and show the ER Diagrams created with Crow's Foot notation. An experienced user spent 10 minutes creating these samples.
Use the Entity-Relationship Diagram (ERD) Solution for ConceptDraw DIAGRAM to create quick and easy your own ERDs using the Crow's Foot and Chen's notations.
All source documents are vector graphic documents. They are available for reviewing, modifying, or converting to a variety of formats (PDF file, MS PowerPoint, MS Visio, and many other graphic formats) from the ConceptDraw STORE. The Entity-Relationship Diagram (ERD) Solution is available for all ConceptDraw DIAGRAM or later users.

When thinking about data visualization, one of the first tools that comes to mind is a flowchart design. You can find flowchart symbols, shapes, stencils and icons easily on the Internet, but it might take time to systematize this information. Nevertheless, once you start flowcharting, you’ll love its simplicity and efficiency.
This diagram consists from standard flowchart symbols, approved by ANSI (American National Standard Institute) for drawing flowcharts. A flowchart is a diagram that represents a step-by-step algorithm of any process, displaying the process stages as boxes that are connected with arrows. Flowchart design makes it clear and readable.
Flowchart designed using ConceptDraw DIAGRAM flowchart software allows to make attractive and clear process presentation, it makes interpretation of the business process flow fresh and versatile. Great flowchart design view is a big advantage over the diagram created manually on a paper.

A waterfall model describes software development process as a sequence of phases that flow downwards. SSADM is one of the implementations of waterfall method. It’s easier to learn about structured systems analysis and design method (SSADM) with ConceptDraw DIAGRAM because this software has appropriate tools for creating data flow diagrams. You can use all the three main techniques of SSADM method with special tools and predesigned templates.
This data flow diagram illustrates the Structured Systems Analysis and Design Method. This method method considers analysis, projecting and documenting of information systems. Data flow models are the most important elements of SSADM and data flow diagrams are usually used for their description. It includes the analysis and description of a system as well as visualization of possible issues.

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.
Diagrams are a very important part of modern life. With the help of flow diagram software, a lot of companies can promote their ideas at the market. Its usefulness is totally doubtless.
This is a flow chart of the invoice payment flow. This flowchart details decrypts all stages of the process of obtaining and paying bills. It is a description of the universal process - such steps performs accounting departments of almost any organization. Since every business no matter what it does is a consumer of some goods or services. The given flow chart was made using ConceptDraw DIAGRAM software and the Diagrams solution for making flowcharts of any kind.
