What is a Data Flow Diagram (DFD)?
A Data Flow Diagram visualizes how data moves through a system, what processes transform it, where it is stored, and which external entities provide or consume it. DFDs use four symbols: External Entity (rectangle, user, supplier, admin), Process (circle or rounded rectangle, what the system does), Data Store (open rectangle, database or file), and Data Flow (arrow, direction of data movement). DFDs are required in Chapter 3 of every BSIT capstone documentation in the Philippines and most universities globally.
The 3 DFD levels you need for capstone
Level 0 (Context Diagram): one process bubble representing the entire system, with all external entities (users, admins, suppliers) and their high-level data flows. Shows scope.
Level 1: decomposes the Level 0 process into 5-8 major sub-processes (Login, Manage Inventory, Generate Report, Process Order, etc.) with data stores between them.
Level 2: further decomposes each Level 1 process. Only do this for the 2-3 most complex sub-processes. Going deeper than Level 2 is over-scope for capstone.

Frequently Asked Questions
What are the levels of a Data Flow Diagram?
DFDs are hierarchical. Level 0 (Context Diagram) shows the entire system as a single process with external entities. Level 1 decomposes that single process into 5-8 major sub-processes with data stores between them. Level 2 further decomposes each Level 1 process into more detailed sub-processes. Most BSIT capstones submit Level 0, 1, and 2 — going deeper is over-scope.
What is the difference between DFD and Flowchart?
DFD shows DATA movement — what data goes where, where it is stored, who produces or consumes it. It has 4 symbols (entity, process, data store, data flow). Flowchart shows CONTROL flow — decision logic, sequence, loops. It has many symbols (decision diamond, process rectangle, terminator oval). For capstone Chapter 3, you typically need a DFD for the data model and a Flowchart (or Activity Diagram) for specific algorithms.
What is the difference between DFD and UML Activity Diagram?
DFD is data-centric — focus on what data is processed and stored, by which process. Activity Diagram is workflow-centric — focus on the sequence of actions, decision branches, parallel work. Many BSIT capstones include BOTH. Older curricula favor DFD (structured systems analysis); newer/OOP curricula favor Activity Diagrams. Check your school's documentation template.
What free tool should I use to draw a DFD?
draw.io / diagrams.net — free, web-based, has a built-in DFD shape library (Gane-Sarson and Yourdon-DeMarco notations). Lucidchart Free — prettier output. Visual Paradigm Community — full DFD support with leveled decomposition. PlantUML supports DFD via plugins. Start with draw.io for capstone — fastest iteration.
Gane-Sarson vs Yourdon-DeMarco notation — which to use?
Gane-Sarson uses rounded rectangles for processes (most common in Philippines BSIT curricula). Yourdon-DeMarco uses circles for processes (older, common in some Indian and US universities). Both are valid. Pick whichever your school's documentation template uses. The semantics are identical — only the shape choice differs.
Are these DFDs free for capstone and thesis use?
Yes. All DFDs are free to download, modify, and submit. No attribution required for academic use. Adapt the external entities, processes, and data stores to your specific system — that is expected good practice.
How often is this DFD collection updated?
New DFDs are added regularly as we encounter new capstone domains (Face Recognition systems, IoT, Cloud-based services). Existing DFDs are reviewed and updated periodically. Last refreshed: May 2026.
