We tailored "FlowMarker," a custom documentation model, specifically to our needs. It is a system designed to document data flow within code in a structured and traceable way. Using unique identifiers (DATAFLOW numbers) and annotations, it indicates whether data is being input, processed, or output, while also referencing predecessor and successor steps. This approach provides clear traceability and helps maintain a comprehensive understanding of data handling throughout the code.
To implement a consistent and trackable way to document data flow within your code, especially when adding or modifying fields in your database, you can adopt a clear commenting system. Here’s a suggested approach:
Comment Structure:
Prefix: Use a prefix like DATAFLOW followed by a unique identifier, such as a sequence number, e.g., DATAFLOW-001.
In/Out Indicators: Indicate if the data is being "Input," "Processed," or "Output," e.g., IN, PROC, OUT.
Description: Provide a short description of the action or the data involved, e.g., Fetching data from DB, Processing user input, Saving to DB.
Predecessor/Successor Indication:
Reference the previous and next steps in the flow, such as Prev: DATAFLOW-002 and Next: DATAFLOW-004. This will help trace the entire process step-by-step. Total: total number of flow markers used.
This method provides clarity, ensuring anyone maintaining the code can quickly understand how data flows through your program, especially when introducing new fields or updating existing ones.
