Question

GIPSY (General Intensional Programming System) is a Demand-Driven Execution System that is based on 
Demand Generators (DGs) that determine the control process by generating functional demands and 
workers that execute them. These workers are potentially remote ones, in which case the demands are 
migrated via the network from the generator to the worker. In that sequence, the problem statement is the 
need of GIPSY Demand Migration System (DMS) that connects the GIPSY’ execution nodes.
The model of our DMS consists of two major contributors called Demand Dispatcher (DD) and Transport 
Agents (TAs). They both run independently, but form together the overall behavior of DMS. The DD acts 
like an event-driven message storage mechanism that uses the TAs to deliver the messages to their 
recipients. The DMS relies on these two contributors to form a communication system similar to the e-mail 
systems, i.e. the messages are delivered when they are asked, but until that moment, they are kept
permanently stored within the message system. The messages in the DMS are demands and results, each 
result being associated with one demand. The Demand Dispatcher (DD) receives demands from the 
Demand Generators (DGs) and results from the workers, and maintains a pool of them. The DD uses the 
TA for transporting these demands and results to the workers and DGs. A DG can cancel its demand at any 
time.

1) Please help me draw the Context Model and Use Case Diagram for this. 

I provided some examples for Context Model and Use Case Diagram. Please I don't want any AI generated answers.
