Components of ER Diagram

Entity-Relationship model gives the possibility to visually describe a database using the components of ER Diagram, entity relationship stencils, relationship symbols, work flow shapes. ER-diagram lets represent the data or entities, attributes of these entities and relationships between them, using standardized Crow’s Foot notation icons or Chen’s notation icons. An entity is an object of the real world, it can exist independently and has the instances which differ in attribute values (properties). The attributes give an unambiguous (uniquely) identification for the instance and are called the primary key, this key can be composite and combine several attributes. ConceptDraw DIAGRAM is a professional software available with Entity-Relationship Diagram (ERD) solution from Software Development area that lets create ERDs for various database systems, using Crow’s Foot and Chen’s notations. It is invaluable tool for software engineers and developers, it supports ODBC-compatible databases (Oracle, MySQL, MS Access, MS SQL, InterBase, Firebird and others).

Interior Design. Office Layout Plan Design Element

Lucky interior design is an integral part of succesful work at office. The important challenge in office design planning is to find a balance between two main office activities: concentration and communication. Primarily you need to determine with a type of office space, this can be an open space or separate rooms. The first type is more suitable for communication and rapid interaction. That's why open offices and combined spaces are modern types of work space and often used, especially for private offices. Traditional office basically represents separate rooms arranged along the corridor. It is applied for the companies with small number of people or for enterprises divided on separate departments, and is practically inapplicable for teamwork. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Office Layout Plans solution offers a lot of vector stencils libraries with design elements of office furniture and equipment for effective office interior design and office space planning, for easy creation Office Floor Plans and Office Layout Plans. Use ConceptDraw DIAGRAM to visualize process flowcharts, network architecture and program workflows like Visio for Mac and even more. The software can be used with different fields like business, engineering and construction, etc.
