ERD Symbols and Meanings

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.

"A baseball field, also called a ball field or a baseball diamond, is the field upon which the game of baseball is played. The term is also used as a metonym for baseball park. ...
The starting point for much of the action on the field is home plate, which is a five-sided slab of whitened rubber, 17-inches square with two of the corners removed so that one edge is 17 inches long, two adjacent sides are 8½ inches and the remaining two sides are 12 inches and set at an angle to make a point. Adjacent to each of the two parallel 8½-inch sides is a batter's box. The point of home plate where the two 12-inch sides meet at right angles, is at one corner of a ninety-foot square. The other three corners of the square, in counterclockwise order from home plate, are called first base, second base, and third base. Three canvas bags fifteen inches (38 cm) square mark the three bases. These three bags along with home plate form the four bases at the corners of the infield." [Baseball field. Wikipedia]
The diagram example "Simple baseball field" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Baseball solution from the Sport area of ConceptDraw Solution Park.

Geo Map - Asia - Saudi Arabia

First of all, Saudi Arabia is known as "the Land of the Two Holy Mosques". Two of the holiest sites of Islam are located in Saudi Arabia. Medina - the city where the Quran was finally approved, and where Prophet Muhammad was buried, and Mecca, the birthplace of Muhammad. Every year, millions of muslims perform hajj and visit Al-Masjid al-Haram - the Sacred Mosque. Unfortunately, the entry is prohibited for non-Muslim people. The citizens of the country live under Sharia law, which impose certain obligations. For example, the usage of drugs and alcohol is forbidden. Gambling is also under the ban. Expats have a possibility to live in special reservations - compounds, where some concessions are allowed, for example, the appearance of women is not so strictly regulated and they have a right to drive there.
