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."

While designing a conceptual data model, you should use appropriate software. For instance, ConceptDraw DIAGRAM is a user-friendly ER diagram tool that has a lot of samples and templates to facilitate your work. A clear entity-relationship diagram helps to define the relations between system’s components.
Software engineering is the section of a computer science engaged to design, realization, and support of complex software products. An ERD is a data modeling method that is widely applied in the software engineering practice. Commonly it is used for developing a structure of a a relational database. An entity relationship diagram is helpful for structuring and organizing databases that can be modeled using a relational structure. An entity relationship diagram is designed to depicts the interrelationships within the sets of entities which are accumulated in the database. Each entity represents a particular component of a data. Thus, ER diagrams depicts the logical structure of databases. ConceptDraw ER Diagrams solution provides software engineers with the professional tool for making entity-relationship diagrams.

When we think about programming, we usually imagine sleepless nights spent on writing kilobytes of code. However, from another point of view, Software development with ConceptDraw DIAGRAM makes a programmer's life endlessly easier. This tool is unique to fulfill all your needs in short period of time.
Over the recent years object-oriented methodology has become more and more widespread. Thanks to this methodology developers manage to deal with growing complexity of applications. More and more programs are written in such programming languages as C++, Java, Visual Basic and Object Pascal. However, the complexity of the designed systems imposes extended requirements as to design of graphic documentation. ConceptDraw possesses powerful tools for designing of technical documentation for object-oriented projects. The libraries included in the package allow to easily draw class hierarchies, object hierarchies and diagrams of data flows with the use of the most popular notations, including UML and Booch notations. And the library for projecting COM-interfaces will spare developers of ActiveX-servers a headache.
