Entity Relationship Software
Entity Relationship Diagram
ERD is a major data modelling tool which can help to organize your project's data into the entities and to define the relashionships between these entities.
It is convenient to design ER Diagrams using ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park. This solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.
In a Chen's notation, entities are represented by rectangles with the entities names inside and relationships are represented by diamonds. The attributes are drawn as ovals and are connected with a line to exactly one entity or relationship set.
Example 1. Entity Relationship Software. Chen's notation
Another type of notation is known as Crow's Foot notation. Fundamentally it is very similar to Chen's notation and differs by designations, are used the boxes to represent entities and the lines between them to represent relationships. The attributes of entity are drawn in the box that represents this entity.
Example 2. Entity Relationship Software. Crow's Foot notation
The Entity-Relationship Diagram (ERD) solution provides templates and samples that allow you get closer with ER diagrams. All they are available for viewing and editing from ConceptDraw STORE.

TEN RELATED HOW TO's:
A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.

Database model is a graphic representation need at the beginning of project development. You won't have any problems with drawing ER diagrams on a Mac anymore with ConceptDraw DIAGRAM application. Special libraries that contain all the symbols of both Chen's and Crow’s foot notation allow you to start database modeling within a few minutes.
Creating entity-relationship diagrams on Mac is fun and effortless when you use a software designed for professional ERD drawing tailored to specific characteristics of Apple OS X. ConceptDraw DIAGRAM is a business diagramming software for those using OS X.
The Entity-Relationship Diagrams solution for ConceptDraw has 2 libraries containing about 50 vector icons, depicting ERD symbols of the most popular Chen's and Crow’s Foot Notations. The other valuable component of the solution is a collection of ERDs samples and templates that can be opened on Macs and PCs.

Working with personnel might be difficult if you are not prepared enough. To explain your workers all the details of communication with customers, you can draw an order process flowchart which will describe every step of the process and answer all the questions that might appear. You can view a lot of business process mapping diagram examples here, in ConceptDraw Solution Park.
This business process flow chart is created to illustrate the sample work order process. Before an organization can make some work for a person, the customer work order request must be completed. It is needed for tracking and accountability objectives. We used this business process flowchart to show a certain tasks and actions assumed by an organization. This flowchart depicts the outside inputs that are needed to launch a process, and ways the organization delivers its outputs. This business process flowchart was created with a help of ConceptDraw Business Process Mapping solution.
