You will be responsible for creating the following: - A top level Context Diagram, which shows the overall system and external entities interactions - A level 0 (zero) diagram, which shows how the entities interact with the main processes in the system Remember, the main purpose of the DFD is to show how data moves in and out of the system, the transformations that take place within the system and what data is stored in the system. Grading The submission will be graded as follows. Document Format - Diagrams are clear and all information is visible and readable - Diagrams use correct symbols for each component - Diagrams do not break any of the DFD Rules presented in lecture Context Diagram - Identifies the external entities and the data flow in and out of the main system Level 0 Diagram - Identifies the major subsystems in the project - Identifies the flow of data from the external entities to each subsystem - Identifies the data stores required Problem Description (Needed for Assignment 1, 2 and 3) A landscaping company currently has no software systems or experience using a software system, everything is achieved using paper methods currently. The landscaping company must track their customers, including each customers schedule for when their landscaping needs servicing, what services need to be performed each time and need to ensure the system takes care of sending invoices and tracking payments received. The landscaping company would also like to be as efficient as possible, making sure they schedule customers who live close to each other on the same day. This would save gas and time, to not have to drive far between customers. A daily map of their route would be an excellent benefit to help with efficiently as well. The company has 5 employees. One employee does in office work (answering the phone, handling invoices, billing and payments). The other 4 employees perform the actual work in two teams (pairs) to complete the landscaping jobs for the day
