In order to model some data, illustrate the logical structure and system design of databases, the Entity Relationship Diagram (ERD or ER Diagram as well as E-R Diagram) was introduced by Peter Chen as a modeling technique for software development. Using three main elements which are attributes, entities and relationships make possible to create so called ERD and to do it with help of ConceptDraw DIAGRAM software is simpler than ever now. As once you download ConceptDraw STORE, you will find the samples of ERDs which you can use for making your own diagram in short terms using all the elements necessary for this purpose. Immensely popular in software engineering this method for modeling database is common for IT engineers use as well as any other IT specialists once they want to succeed in their job. So why not to try our application just now to make sure you keep up with the times and use all necessary tools for achieving your goals?

Very commonly used in the database structure design, the sematic modelling method is one the ways of describing data structures as well as its modelling, based on the meaning of this data. ER-model based diagrams (ERD) consist of these main components: relation, entity and attributes. To be able to create such diagram, you have to mention the entities with their names presented in a form of a rectangle and the relations in a way of non-directional line connecting two entities. To help you to create this chart, we developed ConceptDraw STORE product full of libraries with vector elements you can use for your flowchart. Also we provide you with Solutions section on this site where you can find the numerous stencil libraries, samples and examples to simplify your work with software called ConceptDraw DIAGRAM which is the only one offering that many symbols and templates for making professionally looking smart and mature diagrams.

Design Element: Chen. Professional ERD Drawing

Entity-relationship diagrams or ERD are very well known for representing some data models as well as the relationships and the connections between them. Chen notation was first introduced by Chen and then developed by Barker and it provides lots of data modelling tool as, for example, decomposition charts or attribute diagrams as well as entity-relationship diagrams. The name of the diagram itself explains the reason of creating such type of diagram as it shows the relationship between the different entities which are the real or sometimes abstract objects, such as ideas, people, events, items, conditions, etc. Having ConceptDraw DIAGRAM on your desktop means having lots of design elements for creating any flowchart, charts, diagrams, schemes or plans with help of lots of templates as well as different examples of already existing diagrams, including the ERD. Downloading this application means helping yourself in drawing anything you need in a very short term and having the final result looking very professional.

It may sound very complex, but for those who work with it, especially in IT business, entity-relationship diagram is a very usual thing that can be used for executing the specification of some data warehouse for any designed system and for documenting all of the entities in system as well as their interactions with each other including the important domain objects or entities identification and the properties of these objects which are called the attributes. Also you can make ERD for visualizing relationships of these attributes to some other objects no matter what these objects are. To sum up, ER Diagrams of Crow’s Foot as well as Chen notations can help you to make the chart which consists of elements that are meant to describe each of the system’s element and to make such diagram is better in ConceptDraw DIAGRAM as it is the only one that professional software.
