Design Element: Crows Foot
for Entity Relationship Diagram - ERD
Entity-relationship Diagram (ERD) is a perfect tool which lets execute the detalization of data warehouse for designed system, as well as documenting the entities of the system and their interactions each other, including the identification of important domain objects (entities), the properties of these objects (attributes) and their relationships to other objects.
Creating an ERD requires choosing a specific set of notations that best serve the specific database being designed. Chen’s original notation had a linguistic approach, where boxes representing entities could be thought of as nouns, and the relationships between them were in verb form, shown on a diagram as a diamond.
Eventually Chen’s style was adapted into the Crow’s Foot notation, where relationships were shown as single labeled lines – this quickly became the popular standard, due to improved readability on diagrams, with a more efficient use of space on the page.
ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons.

ER-modeling nowadays is a very popular approach for database design. If you are tired of looking for a good entity relationship diagram Software for Mac, then your search is almost over. ConceptDraw DIAGRAM is a great tool for creating diagrams of any complexity with tons of editable samples and templates.
This diagram represents the vector library of the Chen’s and Crow’s Foot notation icons for drawing ERD (entity-relationships diagram). ConceptDraw Entity Relationship Diagram solution delivers the ability to visualize databases structure on both Mac and PC. The "bricks" entity-relationships models are the entity, and the relation. An entity is represented by a rectangle comprising the entity name. It means an object, information about which should be available and stored. A relation is intended to show a relations between two entities. There are several types of relations between entities. To show there are a number of different symbols for the types of relationships.

Electrical plan is a document that is developed during the first stage of the building design. This scheme is composed of conventional images or symbols of components that operate by means of electric energy. To simplify the creation of these schemes you can use house electrical plan software, which will not require a long additional training to understand how to use it. You only need to install the necessary software ant it’s libraries and you’ll have one less problem during the building projection.
Any building contains a number of electrical systems, including switches, fixtures, outlets and other lightening equipment. All these should be depicted in a building electrical plans and included to general building documentation. This home electrical plan displays electrical and telecommunication devices placed to a home floor plan. On the plan, each electrical device is referenced with the proper symbol. Electrical symbols are used for universal recognition of the building plan by different persons who will be working on the construction. Not all possible electric symbols used on a certain plan, so the symbols used in the current home plan are included to a legend. The electrical home plan may be added as a separate document to a complete set of building plans.

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.

Using diagrams, you can visualize the flow of the information or build a detailed data structure. There's no need to have a degree in software and database design with ConceptDraw DIAGRAM , because this software has all the tools needed in developing models and diagrams. Project planning, designing and prototyping was never so easy.
This UML diagrams can be used to visualize a model of the data base development process. A UML diagram shows a graphical view of a structure of software system: components and relationships.
Using Unified Modeling Language helps to depict logical and physical elements of a data base, visually represent requirements and sub-systems. UML diagrams allows developers to organize and predict critical issues, as well as collaborate data base information.
