ERD Symbols and Meanings

Entity Relationship Diagram Symbols and Meaning - crow's foot notation
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 PRO.

"Cloud computing, also on-demand computing, is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers.
Cloud computing has become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability." [Cloud computing. Wikipedia]
The vector stencils library "Cloud clipart" is included in the Cloud Computing Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Food" contains 38 clipart images of food, fruits, vegetables, meals for drawing illustrations.
"Many cultures have a recognizable cuisine, a specific set of cooking traditions using various spices or a combination of flavors unique to that culture, which evolves over time. Other differences include preferences (hot or cold, spicy, etc.) and practices, the study of which is known as gastronomy. Many cultures have diversified their foods by means of preparation, cooking methods, and manufacturing. This also includes a complex food trade which helps the cultures to economically survive by way of food, not just by consumption. Some popular types of ethnic foods include Italian, French, Japanese, Chinese, American, Cajun, Thai, African, and Indian cuisine." [Food. Wikipedia]
The clipart example "Food - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Artwork solution from the Illustration area of ConceptDraw Solution Park.

This work flow chart sample was redesigned from the picture "Simulation for earthquake disaster assessment" from the article "Simulation Workflows".
[iaas.uni-stuttgart.de/ forschung/ projects/ simtech/ sim-workflows.php]
" This simulation was developed to have an in depth understanding of the destructions and the decisions to be made in various phases of crisis management (Source: Mahdi Hashemi and Ali A. Alesheikh (2010). "Developing an agent based simulation model for earthquakes in the context of SDI." GSDI 12 World Conference. 19 – 22 October 2010. Singapour). The simulation process contains following major steps:
(1) All spatial information including satellite images (before and after the earthquake) and topographic/ cadastral maps of the area are mosaicked and georeferenced. The parts of the city that contain various levels of destructions are selected. Three types of features namely buildings, roads and recreational areas are classified and extracted from the satellite images.
(2) The governing factors of destructions are identified; a mathematical model that integrates the factors is constructed.
(3) The simulation is constructed for various parameter values (different earthquake strength, time elapses, etc.)" [iaas.uni-stuttgart.de/ forschung/ projects/ simtech/ sim-workflows.php]
The example "Workflow diagram - Earthquake disaster assessment" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Workflow Diagrams solution from the Business Processes area of ConceptDraw Solution Park.
