Entity-Relationship Diagram (ERD)

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

Entity Relationship Diagram Examples

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

Software and Database Design with ConceptDraw DIAGRAM

Unified Modeling Language (abbr. UML) is a modeling language used by software developers and software engineers for developing diagrams, expressive modeling, visualization, construction, specification, and documentation an information about software-intensive systems. There are used many types of UML diagrams, joined in main groups, each of them has its own functional abilities and applications: Behaviour diagrams illustrate the functionality of software systems, Structuring diagrams depict a structure of objects at the systems, Interaction diagrams show the flow of control and data among the things in a modeling system. UML has a lot of practical applications in varied areas, among them software development, hardware design, banking and financial services, telecommunication, science, research, enterprise information system, distributed Web-based services, user interfaces for web applications, medical electronics, patient healthcare systems, etc. ConceptDraw DIAGRAM extended with Rapid UML solution is a perfect tool for UML diagramming.

Building Drawing Software for Design Site Plan

Site plan is a detailed architectural plan or document, landscape architecture project for considered object. It is a part of technical design documentation that illustrates the arrangement of buildings, trails, roads, parking, lighting, water lines, sanitary sewer lines, drainage facilities, landscape and garden elements. Site plans are constructed by architects, landscape designers or licensed design engineers, and used by the builders, contractors and installers when constructing or making improvements to some property. They reflect the main design ideas and give an instantly vision of future result after the plan's implementation. They have special value for the large projects of single or multi-floor buildings, and for accomplishment the whole districts. ConceptDraw DIAGRAM extended with Site Plans solution offers the powerful building drawing software tools and vector design elements for development and drawing Site plans and Landscape design drawings, Residential and Commercial landscape designs, Parks and Landscaping territories plans, Yard layouts, etc.

Mechanical Drawing Software

It is impossible to imagine mechanical engineering without drawings which represent various mechanical schemes and designs. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with Mechanical Engineering solution from the Engineering area of ConceptDraw Solution Park offers the set of useful tools which make it a powerful Mechanical Drawing Software.
