Coad/Yourdon's Object-Oriented Analysis model

This DFD sample was created on the base of the figure illustrating "A Survey of Object-Oriented Methods" by Peter Biggs from University of Durham.

"Object-oriented analysis and design (OOAD) is a popular technical approach to analyzing, designing an application, system, or business by applying the object-oriented paradigm and visual modeling throughout the development life cycles to foster better stakeholder communication and product quality.
According to the popular guide Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD activities, analysis models for OOA and design models for OOD respectively, will be refined and evolve continuously driven by key factors like risks and business values."

Software Diagrams

Modern software development begins with designing different software diagrams and also uses a large amount of diagrams in project management and creation graphic documentation. Very popular diagrams that depict a work of applications in various cuts and notations, describe databases and prototype Graphical User Interfaces (GUIs). Software engineering specialists and software designers prefer to use special technical and business graphics tools and applications for easy creation diagrams. One of the most popular is ConceptDraw DIAGRAM diagramming and vector drawing software. ConceptDraw DIAGRAM offers the possibility of drawing with use of wide range of pre-drawn shapes and smart connectors, which allow to focus not on the process of drawing, but on the task's essence. It is a perfect application for design and document development, planning tasks, visualization of data, design the databases, object-oriented design, creation flowcharts of algorithms, modeling business processes, project management, automation of management and development processes, and for many other tasks.

Data Flow Diagram Software

When studying a business process or system involving the transfer of data, it is common to use a Data Flow Diagram (DFD) to visualize how data are processed. Being initially used exclusively in regards to the flow of data through a computer system, now DFDs are employed as the business modeling tools. They are applied to describe the business events and interactions, or physical systems involving data storage and transfer. ConceptDraw DIAGRAM is a powerful Data Flow Diagram software thanks to the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

UML Software

Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems. The Rapid UML Solution for ConceptDraw DIAGRAM presentsthe intuitive RapidDraw interface that helps you to make the UML Diagram of any of these 13 types quick and easy.

Data Flow Diagram Examples

Data flow diagrams (DFDs) are effective to reveal relationships among the various components in a program or system. This type of diagrams is an important and useful technique for modeling an information system, its process aspects, for showing a system as a single high-level process. DFD lets illustrate the flow of data, how the input data are transformed to output results across the sequence of functional transformations. DFD consists of four major components: entities, processes, data stores, data flows. When you need to draw a Data Flow Diagram the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Data Flow Diagrams solution will be helpful for you. Providing numerous collection of Data Flow Diagram examples, samples, templates and ready-to-use vector DFD symbols, Data Flow Diagrams solution ensures you with all needed tools for easy designing DFDs according to Gane-Sarson or Yourdon-Coad notation on your choice. Any from offered predesigned DFD examples can become a perfect base for your own diagram.

Cross Functional Flowchart Examples

ConceptDraw DIAGRAM extended with Cross-Functional Flowcharts Solution from the Business Processes Area is a powerful software which offers a variety of Cross Functional Flowchart examples. The use of predesigned examples as the base for your own Cross Functional Flowchart Diagrams is a timesaving and useful way.

Tools to Create Data Flow Diagram

As a rule, a Data Flow Diagram (DFD) is organized hierarchically from top to bottom and from left to right, and includes all the vital components of the system. Two types of notations are used in common for Data Flow Diagrams: Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution provides powerful drawing tools to create Data Flow Diagram of any complexity. Use the pre-made design components, quick-start templates and samples for quick and easy drawing. Provide the required clarity to the system or process, show the logic and functions, and explain complex concepts and business operations in a visual way using the DFD format.

DFD Flowchart Symbols

A Data Flow Diagram (DFD) is a graphical technique which allows effectively model and analyze the information processes and systems. The ability to fast and easy create the DFDs is made possible with Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park. For designing the Data Flow Diagrams are used simple DFD flowchart symbols which are connected each other by arrows depicting the data flow from one step to another.

Data Flow Diagrams (DFD)

The use of Data Flow Diagrams (DFD) solution as an extension to the ConceptDraw DIAGRAM tool can simplify its users’ work by creating any necessary Data Flow Diagram, which can help simulate multiple data flows and illustrate the functional requirements of the system or business process. Using the pre-made templates and samples of the DFDs, and as the stencil libraries full of DFD-related design elements, any ConceptDraw DIAGRAM user might find the Data Flow Diagrams (DFD) solution a useful tool for making the needed DFD drawings.

DFD - Process of account receivable

"Data flow diagrams are one of the three essential perspectives of the structured-systems analysis and design method SSADM. The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a system's evolution. With a data flow diagram, users are able to visualize how the system will operate, what the system will accomplish, and how the system will be implemented. The old system's dataflow diagrams can be drawn up and compared with the new system's data flow diagrams to draw comparisons to implement a more efficient system. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to report. How any system is developed can be determined through a data flow diagram model.
In the course of developing a set of levelled data flow diagrams the analyst/ designers is forced to address how the system may be decomposed into component sub-systems, and to identify the transaction data in the data model.
Data flow diagrams can be used in both Analysis and Design phase of the SDLC.
There are different notations to draw data flow diagrams (Yourdon & Coad and Gane & Sarson), defining different visual representations for processes, data stores, data flow, and external entities." [Data flow diagram. Wikipedia]
