I need you to draw me Draw Context and Level-0 Data Flow Diagrams...you have all the information down below just draw the two diagrams using that information.

this is the case in case you need it:

"An old school Ice cream shop that was quite popular in the neighborhood for many
years, is suffering huge loss because of the opening of a nearby supermarket that
hosts a variety of ice creams in their freezer section. The ice cream shop was once
popular for their unique flavored ice creams but they are unable to predict the
supply and demand causing many customers to get disappointed because they go
out of stock every so often. The owner of the ice cream shop is your friend and asks
you for advice to resolve this problem. Take him through the SDLC phases and
present requirements, designs and a project plan for your proposed system to the
owner."

Context Diagram

The Context Diagram is the highest-level view of a system, showing the system as a whole and its interactions with external entities.

Entities:

Customers
Suppliers
Ice Cream Shop Staff

Processes:

The Ice Cream Shop System (as one single process)

Data Stores:

Not typically represented at this level.

Data Flows:

Customer Feedback and Orders to the System
Supplier Deliveries to the System
Sales Data and Inventory Updates from the System to Staff

Level-0 DFD

The Level-0 DFD (also known as the Fundamental System Model or Level 1 DFD) expands the single process node from the context diagram into multiple processes, showing how the main system functions are interconnected.

Processes:

Inventory Management
Sales Processing
Ordering and Supplier Management
Demand Forecasting
Customer Feedback Handling

Data Stores:

Inventory Database
Sales Records
Supplier Database
Forecasting Reports
Customer Feedback Logs

External Entities:

Customers
Suppliers
Staff

Data Flows:

Inventory requests and updates between Inventory Management and Staff/Suppliers
Sales information flowing from Sales Processing to Inventory Management and the Sales Records
Orders flowing from Ordering and Supplier Management to Suppliers and Inventory Management
Demand predictions from Demand Forecasting to Inventory Management and Staff
Feedback from Customers to Customer Feedback Handling, and insights flowing to Staff

Given that visual diagrams can't be drawn directly in this text-based interface, I'll outline how you would create these DFDs using a drawing tool:

Context Diagram

Place a single process in the center labeled "Ice Cream Shop System".
Draw external entities around the system: "Customers", "Suppliers", "Staff".
Connect these entities with arrows to and from the central process to represent data flows.

Level-0 DFD

Replace the single central process with multiple process nodes for each of the identified processes (1-5).
Draw data stores as labeled rectangles or open-ended rectangles and connect them to the respective processes with arrows to represent data flow.
Connect external entities to the processes they interact with.
Label the data flows to indicate the nature of information being transferred.
