Think of a retail clothing store in a mall and list relevant data flows, data stores, processes, and sources/sinks. Includes three(3) sales transactions. Draw a context diagram and a level 1 diagram that represents the selling system at the store. Explain why you choose certain elements as processes versus sources/sinks.

Draw me a context-level Data Flow Diagram To draw a context-level Data Flow Diagram (DFD) for the Ice Cream Shop System by hand or using diagramming software, follow these steps: Central Process: In the center of your page, draw a large rounded rectangle. Label it "Ice Cream Shop System" to represent the entire system. External Entities: Draw three rectangles on your page for the external entities: Place one rectangle at the top and label it "Customer" to represent the source of orders and feedback. Place another rectangle at the bottom and label it "Supplier" to represent the entities that supply inventory to the shop. Place the third rectangle to the left side of the central process and label it "Inventory System" to represent the system that tracks inventory levels and provides stock reports. Data Flows: Draw an arrow from the "Customer" rectangle to the central process. Label this arrow "Orders and Feedback" to show the data flow from customers to the system. Draw an…

During the process of conceptual data modelling, what are the four various kinds of E-R diagrams that are built and examined, and what is the purpose of doing so?
Review the order system context diagram and compare it to the order system diagram 0 DFD. Answer the following questions: How many external entities are shown in each diagram? In each diagram, how many data flows connect to the external entities? How many sub-processes are identified in the diagram 0 DFD? Could the datastore have been shown in the context diagram? Why or why not?

1. Draw dataflow diagram for a library management system. A library management system data flow diagram (DFD) shows how the information within a library system needs to flow to meet the needs of patrons or students as well as library administrators. It contains all of the user flow and their entities such as all the flow of Library, Book, Issue Book, Author, Publisher, Employee and Student. The main Entities: • Processing library records and generate report of all library Processing book record and generate report for all book • • Process issue Book records and generate report of all Issue Book Process Author records and generate report of all Author • Process Publisher records and generate report of all Publisher • Process Employee records and generate report of all Employee • Process issue Student and generate report of all Student The main Functional Requirements: Admin logins to the system and manage all the functionalities of Library Management System • Admin can add, edit, delete…
Design an E-R diagram for a database for an airlines system. The database must keep track of customers and their reservations, flights and their status, seat assignments on individual flights and the schedule and routing of future flights. Apply all the database design constraints as much as possible.
7-48. Review the data-flow diagrams given to you by your instructor. Study the data flows and data stored in these diagrams and decide whether you agree with the team’s conclusion that the only six entity types needed are listed in the case and in PE Figure 7-1. If you disagree, define additional entity types, explain why they are necessary, and modify PE Figure 7-1 accordingly.
Draw a Diagram 0 based on the given situation below. You will need to identify external entities, processes, and data stores before drawing the diagrams. (Manually draw and scan the diagram) Fresh-Mart Grocery is a regional grocery chain that is developing an information system to monitor inventory levels, product sales, and merchandise turnover. As products are sold in stores, they need to be replaced by shipments from the distribution centers. The IT manager wants you to document a process called BALANCE that determines whether extra product inventory is needed in a particular store. The BALANCE process is to be used in a just-in- time inventory system that automatically orders products and routes them to various stores for sale. A store manager can override the automatic BALANCE process if he or she so desires to get more product into a store.
Develop a simple data model for a student database that includes student data, student contact data, student demographic data, student grades data, and student financial data. Determine the data attributes that should be present in each table, and identify the primary key for each table. Develop a complete entity relationship diagram that shows how these tables are related to one another.
