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.

How to Add a Block Diagram to an MS Word ™ Document

Block diagram consists of graphic blocks. Blocks are connected by lines or arrows. Block diagrams are used to show the relationship between parts of some systems. It can be used for the development of new systems or to improve existing ones. The structure of the block diagram gives a high-level overview of the major components of the system, as well as the important relationships. Using the block diagrams, you can more effectively present the business data contained in your MS Word documents. ConceptDraw DIAGRAM allows you to easily create block diagrams and then insert them into an MS Word document.
