Following on from your previous work you have been asked to further explore the options you presented and produce the following deliverables:
· Develop a list of requirements for the new system – User Requirements List
· Create a logical data flow diagram of the current business system. Sufficient detail should be included to clearly show all current processes.
· Create a logical data flow diagram for the new business system. The dataflow diagram should clearly show the new processes to sufficient detail to identify all processes.
· Create an E-R Diagram of the system entities for the proposed new payroll and revenue systems, clearly showing the relationships between the entities
· Develop a selection criteria checklist for the evaluation of the solution you identify for the revenue and payroll system for your client.
· Use your selection criteria to compare at least two products and write a 1 – 2 page evaluation report that will include a recommendation of the preferred option.
NOTE: this will be a purely group exercise.Following on from your previous work you have been asked to further explore the options you presented and produce the following deliverables:

Introduction
The aim of the report is to present information about the system analysis and modelling for the current and the proposed payroll and revenue information system for the Maria’s Aquarium Business. The business has scaled up significantly in the past years. Now it is operating from multiple locations. Other than the head office, there are three additional retail outlets in Gosford, Chatswood and Wollongong. The business is also planning to open more outlets at Canberra, Goulburn and Coffs Harbour. And before opening the outlets, it wants to streamline its current business process with the help of an automated information system.
The business bred fishes, both cold water and tropical in their own hatchery and sells the same to the customers. The customers are individuals and wholesalers. At the same time, it stocks various aquarium items from wholesale suppliers and sells the same to customers. Other than the head office and the outlets, they have a hatchery and a warehouse.
In the following sections of the report, there are information about the user requirements, logical data flow diagrams of the current system and the proposed business system, ER diagram, selection criteria for the new payroll and revenue system and comparison of two of such available solutions for the Maria’s Aquarium business.
User Requirements List
The user requirement list of the proposed new payroll and revenue systems are,
Logical DFD of the Current System
Currently, each store runs semi-independent business and data are collected in a paper based information system. There are following types of employees at each of the outlets.
Sales persons handles the selling and taking care of fishes in the store. Storeman processes the deliveries of the stocks of the fishes and the aquarium supplies. And a store manager keeps records of the details of the sales, orders of new stocks from the head office, rosters of the sales staffs in a week and sending the weekly payroll details to the head office. The Payroll system at the head office is a computerised system.
A price book is maintained at the head office and the copy of the same is distributed to all outlets. Head office has an office manager who takes updated prices from the suppliers and updates the same in the price book, or updates the prices from the invoices sent by the suppliers.
When there is a selling activity from any store, the sales person of the store takes the price from the price book and adds that to the customer invoice. Then the sales person collects payment from the customer and updates the daily sales register. Store manager updates the stock cards of each item manually based on the sales of the previous day and the orders for the items and the shipments from the head office. Stock replenishment is also a manual process.
Logical DFD of the New Business System
The proposed information system will track the stock and payroll information automatically and will feed into the proposed accounting and the payroll management system. The logical DFD of the proposed information system is given below,
In this case, the proposed payroll and revenue management system interfaces with the warehouse management process and the automated sales process directly. So, all stock and price related information will be fetched from the system. The system will determine the reorder level and will order items from the supplier. The system will track the employee details also and will prepare rosters for them and will determine their payments.
