Example of DFD for Online Store (Data Flow Diagram) DFD Example

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

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

The vector stencils library "Analog and digital logic" contains 40 element symbols of logic (threshold) gates, bistable current switches, current controllers, regulators, electrical generators, and amplifiers.
Use it for drawing the digital and analog functions in electronic circuit diagrams and electrical schematics.
"Analogue electronics (or analog in American English) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two different levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal." [Analogue electronics. Wikipedia]
"Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry.
In most cases the number of these states is two, and they are represented by two voltage bands: one near a reference value (typically termed as "ground" or zero volts) and a value near the supply voltage, corresponding to the "false" ("0") and "true" ("1") values of the Boolean domain respectively.
Digital techniques are useful because it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.
Digital electronic circuits are usually made from large assemblies of logic gates, simple electronic representations of Boolean logic functions." [Digital electronics. Wikipedia]
The example "Design elements - Analog and digital logic" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

UML Notation

Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems.
Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.
