Creating a ride-sharing software involves several steps, from root level to production. Here's a step-by-step guide on how to do it, including the creation of a Use Case Diagram and a DFD Diagram.

1. **Identify the System Requirements**: The first step in creating a ride-sharing software is to identify the system requirements. This includes understanding the needs of the users, the functionality of the software, and the constraints of the system.

2. **Create a Use Case Diagram**: A Use Case Diagram is a visual representation of the interactions between the system and its users. It includes actors (users or other systems), use cases (functions or services provided by the system), and relationships between them.

- Identify the actors: In a ride-sharing software, the actors could be passengers, drivers, and administrators.
- Identify the use cases: The use cases could be booking a ride, accepting a ride request, managing user profiles, etc.
- Draw the relationships: Show how the actors interact with the use cases. For example, a passenger can book a ride, a driver can accept a ride request, and an administrator can manage user profiles.

3. **Create a DFD Diagram**: A Data Flow Diagram (DFD) is a graphical representation of the flow of data through a system. It shows how input data is transformed into output data through processes.

- Identify the entities: In a ride-sharing software, the entities could be passengers, drivers, and the ride-sharing system itself.
- Identify the processes: The processes could be booking a ride, accepting a ride request, calculating fare, etc.
- Identify the data stores: The data stores could be user profiles, ride history, etc.
- Draw the data flows: Show how data flows between the entities, through the processes, and into the data stores.

4. **Develop the Software**: Once the Use Case Diagram and DFD Diagram are complete, you can start developing the software. This involves coding the functionality, testing the software, and fixing any bugs.

5. **Deploy the Software**: After the software has been developed and tested, it can be deployed to a production environment. This involves setting up the server, installing the software, and configuring the system.

6. **Maintain the Software**: After the software is in production, it needs to be maintained. This involves monitoring the system, fixing any issues, and updating the software as needed.

Remember, this is a simplified version of the process. In reality, software development is a complex process that involves many more steps and considerations.
