Systems Analysis Read the following scenario and answer the questions below. A company hires out property renovation equipment (for example floor sanders, polishing machines, paint sprayers, sandblasters, scaffolding, etc.) to customers. Traditionally, they have used paper based records, but now they want customers to be able to rent out equipment online, or in person from the reception desk. When dealing with a booking, or allocating an available item to a customer, the new system needs to check whether the customer...
