Design Element: Crows Foot . Professional ERD Drawing

ERD or Entity-relationship diagram can be designed using design elements as well as different notations. Yes, 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. Extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park, ConceptDraw PRO software allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons. Find our Entity-Relationship Diagram (ERD) solution which also offers a lot of samples of ER Diagrams of Crow's Foot and also Chen's notations as well as two templates providing useful quick start. In order to make any professionally looking, stylish and attractive Entity-relationship diagram all you need is to download ConceptDraw PRO software and to use ConceptDraw STORE for getting any stencil libraries you need as well as examples and templates. All the samples we provide were created in ConceptDraw PRO software using the Entity-Relationship Diagram (ERD) solution and show the ER Diagrams created with Crow's Foot notation. An experienced user spend usually 10 minutes creating similar to these samples diagrams, for the beginner it can take a little bit longer, but we can ensure all of our clients that the final result will look truly professional as long as they use our Entity-Relationship Diagram (ERD) Solution for ConceptDraw PRO to create quickly and simply create ERDs using the Crow's Foot and Chen's notations.

ERD Symbols and Meanings

Having all necessary design symbols from the vector stencil image libraries with full standardized Chen and Crow’s foot notations as well as knowing all the meaning of all of these stencils means having everything for making entity-relationship diagram in case you have ConceptDraw PRO to draw it there in a short period of time. Having the Entity-Relationship Diagram (ERD) solution that contains a number of ERD templates and samples added to the solution pack which can be used for making any needed diagram in terms of the final result looking really professional and smart is a great thing to get in case it is as cheap as we sell this application for. Mentioning the entities, the attributes and the relationships between these entities means creating ERD or entity relationship diagram. An entity that cannot be uniquely identified by its attributes alone is a weak entity. The existence of a weak entity is dependent upon another entity called the owner entity. The weak entity’s identifier is a combination of the identifier of the owner entity and the partial key of the weak entity. An entity used in a many-to-many relationship (represents an extra table) is an associative entity. The attributes can be key ones, multivalued and derived. In the Chen notation each attribute is represented by an oval containing attribute’s name. The key attribute is an attribute that uniquely identifies a particular entity. A multivalued attribute is an attribute that can have many values (there are many distinct values entered for it in the same column of the table). The derived attribute is the one whose value is calculated (derived) from other attributes. Mentioning all of them in your ERD means making truly professional and smart diagram. Read more

Entity Relationship Diagram Symbols. Professional ERD Drawing

A semantic modeling method nowadays is commonly used in database structure design. Semantic modeling means modeling data structures, based on the meaning of these data. As a tool for the semantic modelling different variants of the entity-relationship diagrams are being used. Mentioning an entity, a relation and attributes is the basic common thing for all entity relationship diagrams or ERDs. An entity uses three-point entry to the entity rectangle, in case many instances of the entity may be used for this relation and single-point entry in case a relation can (or should) participate in only one instance of the entity. Usually an entity is represented by a rectangle which contains the entity’s name. It sometimes cannot be uniquely identified by its attributes alone. The existence of a weak entity is dependent upon another entity called the owner entity. The weak entity’s identifier is a combination of the identifier of the owner entity and the partial key of the weak entity. Some entity used in a many-to-many relationship is called associative entity. Attributes are also an important part of ERDs. Each attribute in the Chen notation is represented by an oval containing attribute’s name. Some attribute that uniquely identifies a particular entity is called a key attribute. The one that can have many values is called multivalued attribute. It is depicted on ERD in a way of a dual oval. Some attribute whose value is calculated (derived) from other attributes is called derived attribute. Once you want to illustrate all mentioned above as well as relationships between those entities and attributes, then we recommend you to start using ConceptDraw PRO right now as it is one of not so many applications which allows to make any needed diagrams, including the ER one offering many design symbols for making it look simply great.
