WHY BALANCING OF DFD IS REQUIRED
WHY BALANCING OF DFD IS REQUIRED
Data Flow Diagrams (DFDs) are an essential tool for visualizing and understanding the flow of data through an information system. They are used in system analysis and design to document the existing system, as well as to design new systems. DFDs are also used in project management to track the progress of a project and to identify potential bottlenecks.
There are many different reasons why balancing of DFD is required. Some of the most important reasons include:
Accuracy
A balanced DFD ensures that all of the data that enters a process also exits the process. This helps to ensure that the data is flowing correctly through the system and that there are no errors.
Consistency
A balanced DFD ensures that all of the data that is processed by a system is consistent. This means that the data is accurate, complete, and timely.
Completeness
A balanced DFD ensures that all of the data that is needed by a system is available. This helps to ensure that the system can function properly and that there are no missing pieces of information.
Performance
A balanced DFD can help to improve the performance of a system by identifying bottlenecks and areas where data is being processed inefficiently. This information can then be used to make changes to the system that will improve its performance.
Security
A balanced DFD can help to improve the security of a system by identifying potential security risks. This information can then be used to implement security measures that will protect the system from unauthorized access.
How to Balance a DFD
There are a few different ways to balance a DFD. The most common method is to use a balancing matrix. A balancing matrix is a table that lists all of the data flows in a DFD and shows how they are connected to each other. The matrix can then be used to identify any data flows that are missing or that are not balanced.
Another method for balancing a DFD is to use a data dictionary. A data dictionary is a repository of information about the data that is used in a system. The data dictionary can be used to check the accuracy and consistency of the data flows in a DFD.
Conclusion
Balancing a DFD is an important step in the system analysis and design process. A balanced DFD ensures that the data is flowing correctly through the system, that the data is accurate, consistent, and complete, and that the system is performing optimally.
