Data structure diagram with ConceptDraw DIAGRAM
Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them.
Data structure diagram is a subspecies of the “entity-relationship” diagram type (ERD).
Entities in data structure diagrams are presented in the form of rectangles or rounded rectangles, and connections between them in the form of arrows. The description of an entity is usually placed inside the rectangle, which denotes the entity. The text description of the entity requirements connecting entities is placed near the line which denotes the connection between entities. The description of connection types between entities (one-to-one, one-to-many, etc.) can be different in different notations and differs with the arrow type on the line of connection between entities. The most famous are notations of DeMarco, Jackson and Yourdon.
DSD also used for hierarchical presentation of the complicated entity. Such data structure diagram is usually created in the result of entity decomposition to the set level of detailed elaboration and presented as a tree.
The difference of the data structure diagram from the “entity- relationship” diagram is that DSD more completely defines connections and relations between elements of entities whereas ERD defines connections between entities.

Unified Modeling Language (UML) is a graphical modeling language for describing, visualizing, projecting and documenting of object oriented systems. UML digram is used for modeling of organizations and their business processes, for development the big projects, the complex software applications. Comprehensive UML diagram allows to create the set of interrelated documents that gives the complete visual representation of the modeling system.

What is a Concept Map and what software is effective for its design? A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts. As for effective software - we suggest you to pay attention for the ConceptDraw DIAGRAM diagramming and vector drawing software. Extended with Concept Maps Solution from the "Diagrams" Area it is a real godsend for you.

Software development flourishes nowadays. Students have tons of educational information and courses that would fit every taste. And it's no secret that knowing how to draw data flow diagrams is a useful skill for a future software architect. The diagrams help a lot in understanding how to storage data effectively and how data processes within a system.
This data flow diagram represents the model of small traditional production enterprise. It was created using Yourdon and Coad notation. The data flow diagram include four main objects: entity, process, data store and data flow. Yourdon and Coad notation uses circles to depict processes and parallel lines to represent data stores. Dataflows are shown as arrowed lines. They are labeled with the description of the data that move through them. Dataflow's role is to deliver the pieces of information. A process's function is to transform. the input data flow into output data flow. ConceptDraw Data Flow Diagrams solution contains the data flow diagram symbols of both Yourdon-Coad and Gane-Sarson notations and a set of handy templates to get started with DFD.

When thinking about data visualization, one of the first tools that comes to mind is a flowchart design. You can find flowchart symbols, shapes, stencils and icons easily on the Internet, but it might take time to systematize this information. Nevertheless, once you start flowcharting, you’ll love its simplicity and efficiency.
This diagram consists from standard flowchart symbols, approved by ANSI (American National Standard Institute) for drawing flowcharts. A flowchart is a diagram that represents a step-by-step algorithm of any process, displaying the process stages as boxes that are connected with arrows. Flowchart design makes it clear and readable.
Flowchart designed using ConceptDraw DIAGRAM flowchart software allows to make attractive and clear process presentation, it makes interpretation of the business process flow fresh and versatile. Great flowchart design view is a big advantage over the diagram created manually on a paper.
