Data flow
Data flow is the movement and transformation of data through the components, operations, or processing stages of a system or program.
100 SQL Server Mistakes and How to Avoid Them
A data flow is an SSIS pipeline that moves rows through source, transformation, buffering, and destination components.
- How it is used
- Moves, imports, exports, and transforms rows within SSIS packages while the control flow orchestrates tasks.
- How deep it goes
- Explains pipeline purpose, component paths, Derived Column expressions, type conversions, and source filtering without detailing buffer internals.
- Examples
- Uses staging impressions, GUID and timestamp conversions, marketing.Impressions loading, and a 30-day aggregate-source filter.
- What you can do after
- Apply it by designing SSIS pipelines that transform rows, expose errors, and reduce source data when performance requires it.

Secure APIs
A data flow is a representation of how data moves between components, users, and external systems.
- How it is used
- Maps application data movement so teams can validate sources and identify security threats across API interactions.
- How deep it goes
- Explains major flow types, validation risks, unsafe consumption, and diagram-based threat modeling without detailing implementation internals.
- Examples
- Uses request and response paths, database transfers, order aggregation, book-format validation, and malicious identity-provider data.
- What you can do after
- Apply it via Microsoft Threat Modeling Tool, OWASP Threat Dragon, or pytm to represent flows and generate threat models.
