Gane Sarson Diagram
"The Gane & Sarson method is based on the building of a logical model of the system, using graphical techniques to enable users, analysts, and designers to get a clear and common picture of the system and how its parts fit together to meet the user's needs.
The methodology involves building a system top-down by successive refinement. First, an overall system data flow is created. Then, detailed data flows are created. Next, the details of the data structures and the process logic is determined. Finally, design of modular structures is begun.
The focus of analysis in the Gane and Sarson method is the Data Flow diagram, which is used to describe the processes of the system, and how the processes transform data."

The vector stencils library Gane-Sarson Notation from the solution Data Flow Diagrams contains specific symbols of the Gane-Sarson notation such as process symbol, connector symbol, jump symbol for ConceptDraw DIAGRAM diagramming and vector drawing software. The Data Flow Diagrams solution is contained in the Software Development area of ConceptDraw Solution Park.
Use the Data Flow solution to draw data flow diagrams for your business documents, presentations and websites.
Example 1. Gane Sarson Diagram
The example above illustrates the Gane-Sarson notation usage for drawing a data flow diagram for on-line appointment scheduling. "The patient enters a web inquiry which generates two checks against different databases, and the information is returned to the patient for acceptance."

Developing a software project supposes architecture first. To make it proper, you can use data flow diagram model in your current project.
The data flow diagram represents the Model of small traditional production enterprise that is made using Yourdon and Coad notation. It shows how the data is transfered through a process. According to the notation of Yourdon and Coad a process is represented by circles and data stores are drawn using parallel lines. This DFD was created using the ConceptDraw Data Flow Diagrams solution. Using this solution one can visualize data flow accordingly to the rules of two basic notations used for data flow modeling.

Astronomy solution provides the Stars and Planets library with wide variety of solar system symbols. You can find here vector objects of solar system, of stars and planets of the universe.
To quickly draw any astronomy illustration: create new document and simply drag the needed solar system symbols from the Stars and Planets library, arrange them and add the text. You can also use the predesigned templates and samples from the ConceptDraw STORE as the base for your own sun solar system illustrations, astronomy and astrology drawings.

A requisition form is one of the documents used for accounting in different manufacturing processes. There are two main types of requisition: a purchasing requisition and material requisition and difference between them is significant. Creating a flowchart might help you in understanding all the details of accounting process.
Flowcharts are a best visual method for dividing a large and complicated procedure into a several little clear pieces. The main value-ability of an effective flowchart is its simpleness. Material requisition flowcharts are used to document the process of relationships between the different departments and the purchasing department within an organization. The flow chart gives the step-by-step guide on how is carried out the procurement process of the materials necessary for the functioning of the organization. This type of flowchart along with many other business flowcharts, one can easy create using ConceptDraw Flowcharts solution.

One of the most popular option helps to draw diagrams faster is pre-designed set of examples related to each kind of diagram. ConceptDraw DIAGRAM software extended with the Workflow Diagrams solution delivers a complete set of workflow process examples helps you to start making your own workflow faster.

When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database projecting and for its' future maintenance.
Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.

Functional modeling allows to make complex business processes simple. One of the basic methods is IDEF0 and one of the most effective also. To create a business model, use flowchart symbols.
The IDEF0 library, supplied with ConceptDraw IDEF0 Diagrams solution contains 18 IDEF0 basic notation symbols. All symbols are the vector graphic images what means, that one can customize their size preserving the stable quality. Another library of IDEF0 symbols can be find out in the the Business Process Diagrams solution, included to the Business Processes section of ConceptDraw Solution Park. These libraries composed from just vector objects and are totally compatible. You can apply the IDEF0 symbols from both libraries at your flowcharts, if needed.
