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.

When we think about programming, we usually imagine sleepless nights spent on writing kilobytes of code. However, from another point of view, Software development with ConceptDraw DIAGRAM makes a programmer's life endlessly easier. This tool is unique to fulfill all your needs in short period of time.
Over the recent years object-oriented methodology has become more and more widespread. Thanks to this methodology developers manage to deal with growing complexity of applications. More and more programs are written in such programming languages as C++, Java, Visual Basic and Object Pascal. However, the complexity of the designed systems imposes extended requirements as to design of graphic documentation. ConceptDraw possesses powerful tools for designing of technical documentation for object-oriented projects. The libraries included in the package allow to easily draw class hierarchies, object hierarchies and diagrams of data flows with the use of the most popular notations, including UML and Booch notations. And the library for projecting COM-interfaces will spare developers of ActiveX-servers a headache.
