Top-level context diagram

This example of a Top Level Context Diagram for an information system management process was redesigned from the Wikipedia file: IDEF Top-Level Context Diagram.jpg. [en.wikipedia.org/ wiki/ File:IDEF_ Top-Level_ Context_ Diagram.jpg]
"Graphical notation.
IDEF0 is a model that consists of a hierarchical series of diagrams, text, and glossary cross referenced to each other. The two primary modeling components are:
(1) functions (represented on a diagram by boxes), and
(2) data and objects that interrelate those functions (represented by arrows).
... the position at which the arrow attaches to a box conveys the specific role of the interface. The controls enter the top of the box. The inputs, the data or objects acted upon by the operation, enter the box from the left. The outputs of the operation leave the right-hand side of the box. Mechanism arrows that provide supporting means for performing the function join (point up to) the bottom of the box.
The IDEF0 process.
The IDEF0 process starts with the identification of the prime function to be decomposed. This function is identified on a “Top Level Context Diagram,” that defines the scope of the particular IDEF0 analysis. ... From this diagram lower-level diagrams are generated." [IDEF0. Wikipedia]
The IDEF0 diagram example "Top-level context diagram" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the IDEF0 Diagrams solution from the Software Development area of ConceptDraw Solution Park.

IDEF0 Visio

ConceptDraw PRO extended with IDEF0 Diagrams solution from the Software Development area of ConceptDraw Solution Park is a powerful diagramming and vector drawing IDEF0 software. All IDEF0 diagrams created in ConceptDraw PRO are vector graphic documents and can be reviewed, modified and converted to MS Visio XML format. To obtain the IDEF0 Visio documents from ConceptDraw PRO documents use the wide export possibilities of ConceptDraw PRO.

IDEF Business Process Diagrams

Use the IDEF Business Process Diagrams solution to create effective database designs and object-oriented designs, following the integration definition methodology.

Types of Flowcharts

A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO

Structured Systems Analysis and Design Method SSADM is the method which is used at projecting and analysis of information systems. SSADM is based on the data flow diagrams. At the description of data flows out of the system and into the system DFD, which denote boundaries of the system, are used.

IDEF0 Flowchart Symbols

The IDEF0 method is built on the functional modeling language Structured Analysis and Design Technique (SADT) and focuses on activity modeling. The ability to create the IDEF0 flowcharts and business diagrams rapidly and without efforts is made possible thanks to wide range of intuitive tools of ConceptDraw PRO software and IDFE0 notation supplied by IDEF0 Diagrams solution from the Software Development area. This solution is rich for the ready-to-use specific IDEF0 flowchart symbols grouped in IDEF0 Diagram library.

IDEF1X Standard

Use Case Diagrams technology. IDEF1x standard - for work with relational data bases. IDEF1x standard is meant for constructing of conceptual schemes which represent the structure of data in the context of the concerned system, for example, a commercial organization.

Data Flow Diagrams (DFD)

Data Flow Diagrams solution extends ConceptDraw PRO software with templates, samples and libraries of vector stencils for drawing the data flow diagrams (DFD).

IDEF9 Standard

Use Case Diagrams technology. An effective management of changes is significantly facilitated by way of definition and documenting of business-requirements.

Database Flowchart Symbols

Database Flowchart Library, Here symbols to design data-base structure, use it to design data base models, or simple data-oriented models. The are special drawing tools for making data flowcharts, data process-oriented diagrams, analysis diagrams and information flow diagrams.

Data base diagrams describes inter-related data and tables. It describes roles and relationships, internal and external dependencies, data exchange conventions and structures of knowledge domain.
ConceptDraw Software provides number of data-base chart libraries including major 49 vector symbols. Use these DFD flowchart symbol libraries to design data-base structure and models, use it to design data base process-oriented models, or simple data-oriented models. The are special drawing tools for making data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams.

Data Flow Diagram Software

When studying a business process or system that involves the transfer of data, it is common to use a data flow diagram (DFD) to visualize how that data is processed. While initially used exclusively in regards to the flow of data through a computer system, DFDs are now employed as a business modelling tool, describing business events and interactions, or physical systems involving data storage and transfer.
ConceptDraw PRO is a powerful Data Flow Diagram Software thanks to the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
You can use the predesigned DFD vector objects that are grouped in 3 libraries of Data Flow Diagrams solution: Data Flow Diagrams Library; Gane-Sarson Notation Library; Yourdon and Coad Notation Library.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

Gane Sarson Diagram

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 PRO diagramming and vector drawing software. The Data Flow Diagrams solution is contained in the Software Development area of ConceptDraw Solution Park.
