Entity Relationship Diagram Symbols

The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park. This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.

Interior Design

Interior design is simultaneously the science and art directed on beautification of interior space with the aim to provide convenience, comfort, aesthetic for pleasant staying of people. Interior design is very multifaceted, it includes the processes of interior design development, space planning, research, communication with project's stakeholders, programming, management, coordination, site inspections, all they are realized directly by interior designers or under its supervision. Creation of interior design project lets you plan and optimize the space, improve the navigation inside large premises, develop the decoration project according to the chosen style, create the lighting plan, ventilation scheme, plumbing and heating plans, and schematic of furniture arrangement. Numerous solutions from Building Plans area of ConceptDraw Solution Park contain examples, samples, templates and vector stencils libraries helpful for development the interior designs of different styles, for professional creation the interior design drawings and using them for technical documentation.
