The below is how the template of a database model diagram looks like in EdrawMax.Ĭlick on the “Library” button found in the left menu, and then you can enable all the symbol libraries of ER diagrams that are pre-defined in EdrawMax, including Crow’s Foot Database Notation and Chen’s Database Notation. You can choose and open one of the pre-made ER diagram templates to save your time of building the ERD from scratch. ĭouble-click the icon of Chen ERD or other types of diagrams to open a blank drawing page.

Install EdrawMax on your computer or visit EdrawMax Online. Right-click on the attribute to set its type (primary key, multivalued attribute, derived attribute, or required attribute). Release the attribute over the entity to connect the entity and the attribute. Drag "Attribute" from the stencil towards the entity. Drag the other end of the connector to the other entity. This will connect the connector to the entity. Drag a Relationship Connector shape over the entity. Now, start drawing the entities by dragging an Entity shape from Chen's Notation stencil. Step 1: Open Visio and Choose the diagram type. Follow the steps below to draw an ERD using Chen’s notation in Visio. In this notation, rectangles represent entities, ovals represent attributes, and the relationship is shown with a diamond shape and some description.

Chen’s notation is commonly used for brainstorming and quick diagramming. Such an ER Model helps in understanding database structures. Customize it according to your needs.Ĭhen’s Database Notation is used to present an abstract view of associations between entities. Click on the "Set Begin Symbol" and "Set End Symbol" to set the start and end cardinality, respectively. Drag the ends of the relationship line to connect it to the entities or their attributes.Īfter drawing the line, set the cardinality by right-clicking on the relationship line. In this step, drag a Relationship shape from the stencil to draw the relationships between entities. Step 3: Draw the relationships and cardinality. Now, start drawing the entities by dragging an Entity shape from the Crow’s Foot Database Notation stencil. Go to the File menu, click on “New” and select “Crow’s Foot Database Notation.” Then choose the desired unit system and click on “Create.” Now, following are steps of using Crow’s Foot Notation in Microsoft Visio to make an ERD. It communicates complex relationships in an easy-to-understand manner. It describes the relationship with the help of connected lines, with symbols at either end that describe the relationship's cardinality. We will explain making an ERD first by using the Crow’s Foot Notation and then Chen’s Database Notation.Ĭrow's Foot Notation is a simple notation that helps illustrate the relationship between entities. Each stencil uses specific symbols for the representation of entities and relationships. Visio provides you with two stencils for different kinds of ERDs. So, we will look into the steps of creating an ER diagram in Visio. Microsoft Visio is a visualization tool that shows data in an easy-to-understand manner.
