Affinity Diagram Software

This example of cloud computing system architecture diagram was created on the base of picture in the article "What is StorSimple?" by Sharon Smith from the Microsoft Azure website.
"Microsoft Azure StorSimple is an efficient, cost-effective, and manageable solution that eliminates many of the issues and expense associated with enterprise storage and data protection. It uses a proprietary device (the Microsoft Azure StorSimple device) and integrated management tools to provide a seamless view of all enterprise storage, including cloud storage."

The diagram example "Microsoft Azure StorSimple architecture" was created using ConceptDraw PRO diagramming and vector drawing software extended with the Azure Architecture solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Chemical drawings" contains 81 symbols of organic compounds and functional groups for chemical drawing.
Use it to draw structural formulas of organic molecules, schemes of chemical reactions and organic chemistry diagrams.
"Structural drawings.
Organic molecules are described more commonly by drawings or structural formulas, combinations of drawings and chemical symbols. The line-angle formula is simple and unambiguous. In this system, the endpoints and intersections of each line represent one carbon, and hydrogen atoms can either be notated explicitly or assumed to be present as implied by tetravalent carbon. The depiction of organic compounds with drawings is greatly simplified by the fact that carbon in almost all organic compounds has four bonds, nitrogen three, oxygen two, and hydrogen one. ...
Organic reactions.
Organic reactions are chemical reactions involving organic compounds. While pure hydrocarbons undergo certain limited classes of reactions, many more reactions which organic compounds undergo are largely determined by functional groups. The general theory of these reactions involves careful analysis of such properties as the electron affinity of key atoms, bond strengths and steric hindrance. These issues can determine the relative stability of short-lived reactive intermediates, which usually directly determine the path of the reaction.
The basic reaction types are: addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions and redox reactions. ...
Each reaction has a stepwise reaction mechanism that explains how it happens in sequence - although the detailed description of steps is not always clear from a list of reactants alone.
The stepwise course of any given reaction mechanism can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition through intermediates to final products." [Organic chemistry. Wikipedia]
