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.

The vector stencils library "Wireframe grid" contains 7 web page layout design patterns.
Use these grids to position content and widgets on your web pages using the ConceptDraw PRO diagramming and vector drawing software.
"In graphic design, a grid is a structure (usually two-dimensional) made up of a series of intersecting straight (vertical, horizontal, and angular) or curved guide lines used to structure content. The grid serves as an armature on which a designer can organize graphic elements (images, glyphs, paragraphs) in a rational, easy to absorb manner. A grid can be used to organize graphic elements in relation to a page, in relation to other graphic elements on the page, or relation to other parts of the same graphic element or shape. ...
While grid systems have seen significant use in print media, interest from web developers has only recently seen a resurgence. Website design frameworks producing HTML and CSS had existed for a while before newer frameworks popularised the use of grid-based layouts. Some grid systems specify fixed-width elements with pixels, and some are 'fluid', meaning that they call for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points." [en.wikipedia.org/wiki/Grid_(graphic_design)]
The webpage layout patterns example "Design elements - Wireframe grid" is included in the Website Mockup solution from the Software Development area of ConceptDraw Solution Park. Read more
