ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Flowchart Programming Project. Flowchart Examples

Flowcharts can be used in designing and documenting both simple and complex processes or programs and, similar to the other types of diagrams, they can help visualize what happens and so help understand some definite process, and, as a result, find flaws, bottlenecks and other features within it.

Design Pictorial Infographics. Design Infographics

In the course of recent decades data visualization went through significant development and has become an indispensable tool of journalism, business intelligence and science. The way visual information may be conveyed is not limited simply to static or dynamic representation, it can also be interactive. Infographics can be conditionally divided into several general levels. Primarily, this is level of visualization of information, its interpretation and association on any ground. Second level can be defined as a visualization of knowledge, depiction of thoughts and ideas in the form of images or diagrams. Finally, the level of data visualization, which processes data arrays in charts, enabling the information to be more clearly perceived. You can also identify the main approaches to the creation of infographics: exploratory and narrative. Exploratory method insists on minimalist design in favor of data precision without unnecessary details and is common for scientific researches and ana
