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.

How to Draw ER Diagrams *

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.

ERD Templates

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.

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.

IDEF0 Flowchart Symbols →

Functional modeling allows to make complex business processes simple. One of the basic methods is IDEF0 and one of the most effective also. To create a business model, use flowchart symbols. The IDEF0 library, supplied with ConceptDraw IDEF0 Diagrams solution contains 18 IDEF0 basic notation symbols. All symbols are the vector graphic images what means, that one can customize their size preserving the stable quality. Another library of IDEF0 symbols can be find out in the the Business Process Diagrams solution, included to the Business Processes section of ConceptDraw Solution Park. These libraries composed from just vector objects and are totally compatible. You can apply the IDEF0 symbols from both libraries at your flowcharts, if needed.IDEF0 Flowchart Symbols *

How To use House Electrical Plan Software →

Electrical plan is a document that is developed during the first stage of the building design. This scheme is composed of conventional images or symbols of components that operate by means of electric energy. To simplify the creation of these schemes you can use house electrical plan software, which will not require a long additional training to understand how to use it. You only need to install the necessary software ant it’s libraries and you’ll have one less problem during the building projection. Any building contains a number of electrical systems, including switches, fixtures, outlets and other lightening equipment. All these should be depicted in a building electrical plans and included to general building documentation. This home electrical plan displays electrical and telecommunication devices placed to a home floor plan. On the plan, each electrical device is referenced with the proper symbol. Electrical symbols are used for universal recognition of the building plan by different persons who will be working on the construction. Not all possible electric symbols used on a certain plan, so the symbols used in the current home plan are included to a legend. The electrical home plan may be added as a separate document to a complete set of building plans.House Electrical Plan Software
