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."

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 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."

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.

If you have doubts about some situation, there are tools that might help you. First used in the Stanford Research Institute in the 60s, SWOT analysis is a great solution and if you need to build a strategy, this tool is very effective. As a result, you will get the clear idea of all the opportunities and threats you might face.
This matrix was build for a TOWS analysis performance. A TOWS analysis includes the same process of listing strengths, weaknesses, opportunities and threats as a SWOT analysis. But, unlike SWOT, TOWS analysis primarily takes into account threats and opportunities and then at least - weaknesses and strengths. This is also a is a strategic planning tool. Beyond making a matrix, the strategy manager should investigate ways the organization can take edge of opportunities and reduce threats by turning to advantage strengths and weaknesses. Making SWOT and TOWS analysis uses the same approach and outputs close results. ConceptDraw SWOT and TOWS Matrix Diagrams solution supplies templates of matrices, that help to list clearly the constituents of SWOT and TOWS analysis.
