How to Draw ER Diagrams
How to Draw ER Diagrams? ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the ERD drawings and ER Diagrams. Entity Relationship diagram depicts database by abstract way.
Entity-Relationship Diagram (ERD) solution from the Software Development Area for ConceptDraw Solution Park includes 45 predesigned icons advocated by popular Chen's and Crow’s Foot notations that can be used when describing an enterprise database.
Sample 1. How to Draw ER Diagrams
The easiest and fastest way of drawing ER diagrams is to design them on the base of ready-to-use Chen ERD and Crow's Foot ERD templates. They both are represented at ConceptDraw STORE.
Example 2. ERD Templates
Use the corresponding template and other objects from the ERD Chen's Notation and ERD Crow's Foot Notation libraries to design your Entity-Relationship Diagram in a few minutes.
Example 3. Entity-Relationship Diagram, Crow's Foot Notation
Another way of easy drawing ER diagrams in ConceptDraw DIAGRAM is:
- create new ConceptDraw document,
- add required objects from the libraries,
- connect the objects with Smart Connector tool from the Home toolbar,
- use the Action menus of the objects to change diagram elements,
- apply Line, Fill, Shadow and Text tools to format diagram objects.
Example 4. Entity-Relationship Diagram, Chen's Notation
The ER Diagrams you see on this page were created in ConceptDraw DIAGRAM using the libraries from Entity-Relationship Diagram (ERD) solution. An experienced user spent 10-15 minutes creating each of these samples.
Use the Entity-Relationship Diagram (ERD) Solution for ConceptDraw DIAGRAM software to demonstrate how to draw ER Diagrams fast, easy and effective.
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.
TEN RELATED HOW TO's:
Both Crow’s Foot and Chen’s notations are used to build database models. Each of them has its’ own features, and if you use a proper entity relationship diagram software, you’ll be able to create diagrams of any notation. Database model with clearly defined entities and relationships between them facilitates further work greatly.
This ERD represents the model of Employee Certification Entity. The entity-relationship diagram is a visual instrument of database software development. It is used to structure data and to define the relationships between structured data groups. This ERD was designed with a help of ConceptDraw Entity-Relationship Diagram (ERD) solution. The solution supports the both basic ERD notations used to describe the structure of database: Chen's and Crow’s Foot notations.

The vector stencils library Chen ERD from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Chen ERD notation including entity symbols and relationship symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.

ER diagram is the most popular database design tool which lets create graphical representations of database tables, their columns and also relationships. As for the Mac users, they are very interested in powerful database diagramming tools and ER diagram tool for OS X to design professional looking E-R Diagrams and ERD drawings. ConceptDraw DIAGRAM software on Mac OS X gives the ability to easy draw ERDs.

This template shows the Context Diagram. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Block Diagrams Solution from the “Diagrams” area of ConceptDraw Solution Park.
The context diagram graphically identifies the system. external factors, and relations between them. It’s a high level view of the system. The context diagrams are widely used in software engineering and systems engineering for designing the systems that process the information.

It is very difficult to get into database model idea without any examples. To create one, you can use Chen’s notation for Entity Relationship Diagrams (ERD) and try to see all the peculiarities yourself. This notation describes entities and relations as basic geometric shapes like rectangles and diamonds.
Chen notation for Entity-relationship diagrams is used for designing relational databases. It depicts the database entities as a set of subjects. For example events, people, ideas, etc. All entities has common characteristics (attributes). Any object of the system is identified as the sole and unique. The name of entity should indicate the class or type of the the whole object, not a given example. The connection commonly represents a relationship between entities. Conceptdraw Entity-Relationship Diagrams (ERD) solution provides the libraries with ready-to-use ERD element fitting Chen's notation objects and relationships.

Using ConceptDraw you will be able to create bubble diagrams from the ready ConceptDraw library objects or make your own objects. The created diagram can be saved and edited, objects can be moved and links between them will be automatically repainted after object moving because of using the ConceptDraw connectors.

ConceptDraw DIAGRAM application is perfect for creating workflow diagrams. This application contains specific features and technologies designed to draw diagrams faster, such as RapidDraw and Arrows10. ConceptDraw DIAGRAM software extended with the Workflow Diagrams solution gives you a flexible tool to draw any kind of workflow.

Plumbing systems are very important for any manufacture, and it's a good practice to have a clear scheme of that system. To create one, you should use a piping and instrumentation diagram software with a possibility to save files in vector format, so you can print them without quality loss. ConceptDraw DIAGRAM is a great tool for creating diagrams, and you don't need to be very experienced to use it efficiently.
This example of Piping and Instrumentation Diagram (P&ID) depicts a scheme that illustrates the physical sequence and functional communications of piping, instrumentation and plumbing equipment components of a typical food trailer.
Seeking to avoid health troubles in a mobile food service , the plumbing demands for food trailers must be considered accurately. This P&ID shows all of piping including a basic set of piping system components along with multiple sinks, extra water heaters and other elements to meet health guidelines.

If your company is in chaos in clutter and no one understands their rights and responsibilities, maybe it's time to change that. One of the ways to put the company in order is to draw an organization chart that would reflect the structure and show the relationships among departments and positions. This is a very useful and easy to understand scheme.
This is example of the one of the most typical kind of organizational chart. It depicts an organizational structure of the hierarchical type. Its construction is similarv to pyramid. The single main position on the top - in this case, the mayor's position followed by sub-levels of authority in his command. Each position in the pyramid reports only to his supervisor, and takes only a report of direct subordinates. Such scheme limits the number of communications. This organizational structure is effectively used in public organizations. Also it is suitable for any organization with the need for multiple levels of middle managers. The ability to create organizational charts of different types is supplied with ConceptDraw Ogrcharts solutions.
