- A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.arrow_forwardData modeling is most often accomplished through the use of a(n) __________________. a. entity-relationship diagram b. data-flow diagram c. functional decomposition diagram d. activity diagramarrow_forwardFill in the blank: A ____________________ is a structured collection of related data stored on a computermedium.

A laptop computer is taken to the meetings, and is used to add the names of new members to the group. The diagram represents an online process and is the child of the process 1, ADD NEW MEMBERS. The following tasks are included: 1. Key the new member information. 2. Validate the information, errors are displayed on the screen. 3. When al, the information is valid, a confirmation screen is displayed. The operator visually confirms that the data are correct and either accepts the transaction or cancels it. 4. Accepted transactions add new members to the MEMBERSHIP MASTER file, which is stored on the laptop hard drive. 5. Accepted transactions are written to a MEMBERSHIP JOURNAL file, which is stored on a second hard drive.arrow_forward
- ______ represent real-world associations between entities.arrow_forwardYou own a software development company that has been hired to build an online classified ads website (refer to Craigslist.com as an example). Data and Process Modeling Using a free design tool, create a Context Diagram for the e-commerce system based on the requirements you identified. Remember to consider the internal and external actors (people and other systems) that our system might interact with. Think about the types of data that are going to flow in and out of the system. This might be a good opportunity to revise your requirements if necessary. Now create a Diagram 0 DFD for this system. Make sure you “zoom in” from the context diagram and include all the major internal systems, process, data flows, and data stores. Now create one Lower-Level DFDs (based on processes you identified in your Diagram 0). Pay special attention to the leveling & balancing techniques outlined in the textbook. These “exploded” process diagrams usually correspond to the process…arrow_forwardCompose conceptual data modeling techniques that capture information requirements.arrow_forward
- Entity-Relationship Diagram (ERD) is one of the data modeling tools that provides a software engineer with the ability to represent data objects, their characteristics, and their relationships. Use an ERD to describe the following scenario. A teacher is identified by an ID number (TID), last name (LName), and first name (FName). A project is identified by a project ID (PID) and title (T). A student is identified by an ID number (SID), last name (LName), and first name (FName). A teacher can supervise zero, one, or many students and a student is supervised by one teacher. A teacher must propose one or many projects and every project is proposed by one teacher. A student must work on one project and every project is worked by only one student.arrow_forwardAn Entity Relationship (ER) Diagram is a type of flowchart that illustrates how “entities” such as people, objects or concepts relate to each other within a system. Consider the following description of a system: A university registrar’s office maintains data about following entities: Courses, including number, title, credits, syllabus, and prerequisites. Course offerings, including course number, year, semester, section number, instructor, timings and classroom. Students, including student-id, name, and program. Instructors, including identification number, name, department, and title. Furthermore, the enrollment of students in courses and grades awarded to students in each course they are enrolled for must be appropriately modeled. Construct an ER Diagram for the registrar’s office. Document all assumptions that you make about the mapping constraints.arrow_forwardScenario: You are part of a development team that is responsible for converting data from a legacy (already existing) system so that the data can be incorporated into a new Enterprise Resource Planning (ERP) system. During the process of examining the existing system and its data, you discover that several country location fields were mismanaged by the existing software, resulting in the company selling GMO (genetically modified organism) seeds not explicitly listed or labeled as being GMO in the affected countries. GMO seeds are completely unregulated in some countries, regulated and legal in others as long as they are labeled as GMO according to local regulations, and completely banned in yet others. Question: Assume that your supervisor tells you to ignore what you have found, and to just "fix the rules and adjust the data" so that the problem will not be allowed to migrate into the new system. What (if any) additional/continuing obligations do you then have?arrow_forward
