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.

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.

Data Flow Diagram Model →

Developing a software project supposes architecture first. To make it proper, you can use data flow diagram model in your current project. The data flow diagram represents the Model of small traditional production enterprise that is made using Yourdon and Coad notation. It shows how the data is transfered through a process. According to the notation of Yourdon and Coad a process is represented by circles and data stores are drawn using parallel lines. This DFD was created using the ConceptDraw Data Flow Diagrams solution. Using this solution one can visualize data flow accordingly to the rules of two basic notations used for data flow modeling.Data Flow Diagram Model *

Diagram of a Basic Computer Network. Computer Network Diagram Example →

What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable. This sample shows the connection scheme of the home WLAN equipment to the Internet.Diagram of a Basic Computer Network

UML Diagram →

While developing software, it is very important to have a visual model, because it helps to represent the logic and the architecture of an application. Experienced engineers use UML diagrams to denote relationships between classes and their instances. UML is a general language for a set of diagrams like deployment diagrams, object diagrams or use case diagrams. This diagram represents UML class diagram used for a software system development using an object-oriented method. Class diagrams are categorized as static structure diagrams that depict the physical structure of a system. Class diagram divides a software system's structure into "classes". Classes are defined by the methods and variables of objects. UML Class diagram is used to depict relationships and source code dependencies between objects.UML Diagram *
