请求协助创建OTMC系统的Level 0 DFD（数据流图）

Core Process Breakdown #

• Member Registration: Collect essential user information (name, mailing address, credit card details) and process subscription sign-ups, including special requests like double coffee shipments or computer game-specific preferences (genre, age rating). Use the submit-membership-form command to validate and store data in the system.
• Product Delivery: Generate monthly shipment schedules based on membership type and quantity. This process retrieves member data and inventory levels to create shipping labels and update stock records.
• Membership Management: Handle membership adjustments such as switching to new service categories (e.g., cheese, toys), changing subscription durations (3/6/12 months), or updating contact/payment details.

Key System Constraint #

OTMC plans to expand membership services significantly, so the system must be adaptable to future additions without major overhauls.

For internal documentation, refer to the OTMC Use Case Reference to align DFD with existing system design.
