So while any data flow diagram maps out the flow of information for a process or system, the logical diagram provides the “what” and the physical provides the “how.” They are two different perspectives on the same data flow, each designed to visualize and improve the system.

A data flow diagram (DFD) maps out the flow of information for any process or system. It uses defined symbols like rectangles, circles and arrows, plus short text labels, to show data inputs, outputs, storage points and the routes between each destination.

This data flow diagram (logical) template can help you: - Map out the flow of information for any process/system. - Visualize business processes. - Optimize your current process and plan for a new data flow process.

Logical Data Flow Diagram (Click on image to modify online) Physical data flow diagrams focus on how things happen in an information flow. These diagrams specify the software, hardware, files, and people involved in an information flow.

Lucidchart makes it easy to create a customized data flow diagram starting with a simple template. Choose the symbols you need from our library—processes, data stores, data flow, and external entities—and drag-and-drop them into place.

A data flow diagram (DFD) illustrates the flow and transformation of data for a particular business process. It’s a visual representation of how data flows through a system, so you can clearly see where the data comes from, where it goes, and how it gets stored.

Our data flow diagram software makes creating large, complex data flow diagrams simple. Lucidchart includes features like conditional formatting, action buttons, external links, and layers. With our help, your diagram will capture all the information …

Whether you’re building a simple Level-0 DFD or mapping deeper levels of data flows, you can create a professional depiction of any system or process with our context diagram tool that offers access to hundreds of engineering templates and dedicated shape libraries containing industry-standard symbols.

Find out how to make a data flow diagram in Microsoft Word. This step-by-step guide outlines how to manually create a DFD in Word using the shape library and with Lucidchart add-in. Templates included!

A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols.
