Data Flow Diagrams (DFDs) are carried out in the Structured Analysis phase.

Here's a step-by-step explanation:

1. Structured Analysis: This is the phase where DFDs are primarily used. In this phase, the system is studied in a detailed manner. The main aim is to gather information and requirements. DFDs are used to represent the flow of data within the system, which helps in understanding how the system will work.

2. Structured Design: This phase comes after the analysis phase. Here, the physical aspects of the system are designed. While DFDs can still be used in this phase, they are not the primary tool.

3. Decomposed Level Design: This is not a phase in system development, but rather a level of detail in DFDs. A decomposed DFD breaks down a complex system into simpler parts for better understanding.

4. Low Level Design: This is the phase where the actual software components are designed. It involves detailed design of data structures, algorithms, and interfaces. DFDs are not typically used in this phase.
