Data Flow Diagrams
With ConceptDraw DIAGRAM you can design professional flow chart diagrams, as well as:
- Unified Modeling Language (UML) diagrams
- Entity Relationship Diagrams (ERD)
- Data Flows Diagrams (DFD)
- Structured Systems Analysis and Design Method (SSADM)
- Windows and Macintosh Graphics User Interface (GUI) design
ConceptDraw DIAGRAM enables you to quickly create data flow diagrams that include data storage, external entities, functional transforms, data flows, and control transforms and signals.
All information systems manage the flow of data introduced into the system. The visualization of data flows represents the activity of data moving and transforming as it moves through a defined business system.
Complex information systems contain data flows which can be represented as a data flow diagram. Data flow diagrams enable you to visualize the data flow as well as it provides you the ability to analyze and make modifications to business systems.
With ConceptDraw DIAGRAM it is easy to create a data flow diagram from the supplied shapes located in the Object Library. The Object Library contains a large number of shapes that can be used to represent data flows, processes, data storage, objects and other data flow entities.
Solutions from the Software Development Area of ConceptDraw Solution Park extend ConceptDraw DIAGRAM (or later) comes with hundreds of work templates and an extensive range of libraries that give you the ability to represent your models. With ConceptDraw DIAGRAM you can quickly create a diagram and then export it to many graphic formats, including Microsoft PowerPoint.

The first thing that usually comes to mind when talking about database models is ER-diagrams, and the ways to create them. The second most recognizable notation is the Crow’s Foot, which visually differs from Chen’s notation. Actually, it doesn’t matter which notation you’ll use for your entity relationship diagram (ERD), but the content is what matters.
When designing an Entity-Relationship Diagram one need to use a certain notated symbols that were developed and standardized especially for databases description. First of them - the Chen’s notation had a linguistic origin. It includes rectangle boxes to show entities that may be described as nouns, and the relationships between them described as verbs depicted in a form of diamond. Finally the Chen’s notation was simplified up to the Crow’s Foot notation. It represents a relationship as labeled line. It is precisely this notation is shown in the given figure. ConceptDraw DIAGRAM together with its Entity-Relationship Diagram (ERD) solution is designed to support professionals who deals with creating ER diagrams using the element of both - Chen’s and Crow's Foot notations.

When you need to visually represent the structure of relational database, Entity relationship diagram (ERD) is a type of diagram for that case.
Most entity-relationship diagrams can be built with objects from Flowchart solution or ERD Solution which contains inbuilt templates. Follow these steps to create your own custom ERD diagram.
Don't be frightened if it looks complex, ConceptDraw DIAGRAM makes it easy to create an ERD, and hundreds of other diagrams, in minutes.

The diagrams with highest level in the hierarchy define the main processes or subsystems with external and internal data sources. To detail them, DFD Library is used to build a system of lower level diagrams. This decomposition continues hereinafter it is meaningless.
This data flow diagram of a system of a library management is a context-level DFD. The data flow diagram of this type depicts the large system as a solid process, and does not input any explanation of its content. It is an ordinary practice - creation of a context-level data flow diagram when starting system development. This DFD was made using ConceptDraw solution designed especially for data flow diagrams development. One can find out Data Flow Diagrams Solution in a Solution Park of ConceptDraw and can use in as addition to the common Conceptdraw DIAGRAM diagramming tools.
