A hierarchy chart of modules and a flow chartPart 1
You manage a dog-walking service, in which you interact with
both clients and dog walkers. Your task is to schedule dog-walking appointments
based on the clients' requested dates and times and the availability of the dog
walkers. Once a dog walker has been assigned for a particular appointment, the
appointment has to be confirmed with both the client and the dog walker.
Finally, the client has to be billed and the dog walker has to be paid.
Write down which variables you would need in order to write
a software application for dog walking scheduling, and identify the data type
for each variable.
