Gane Sarson Diagram
What is the Gane and Sarson Model?
"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."

Process mapping helps with sharing business results and reorganizing workflow. In almost every case, after creating a sales process flowchart the steps that are redundant become obvious for a manager. It's easy to find a flowchart examples that will help in developing one for your business.
This sales process flowchart consists of a sequence of steps that represent a simple sale process. Each step is shown graphically by a rectangle representing processing steps or an activity, or a diamond representing a decision. These rectangles are linked by arrows, that indicate the direction of the sales workflow. ConceptDraw Sales Flowcharts solution delivers a the full set of classical flowchart notation symbols, along with sales-related icons and pictograms.

There are a lot of structured analysis and design technique methodologies used to describe systems and data sources. To visualize data structures, data flow diagrams can be used for various purposes in the area of software engineering. Nowadays these diagrams are also used in the area of business analysis and information system analysis.
This data flow diagram depicts an account processing system of a typical account department of a small manufacturing enterprise. It shows the data transmission through the order processing to shipping verification. This data flow diagram was created according to standard of Yourdon and Coad notation. The vector graphic objects of Yourdon/Coad notation symbols was delivered by ConceptDraw Data Flow Diagrams solution. The current DFD can be employed as an example of a business process model, representing the set of business events and interactions commonly engaged in a accounts receivable process.

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.

The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data.
This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.
