I have a HW that is asking me to draw on ERD diagram for a simple purchasing system that has order with order id, customer id, and date; order consists of one or more items; items consist of item id, description and price, and customers list customer id, name, and address. Can you help?
Suppose we have a database for an university. The requirements are as follows: • Professors have an SSN, a name, an age, a rank, and a research specialty. • Projects have a project number, a sponsor name (e.g., NSF), a starting date, an ending date, and a budget. • Graduate students have an SSN, a name, an age, and a degree program (e.g., M.S. or Ph.D.). • Each project is managed by one professor (known as the project’s principal investigator). • Each project is worked on by one or more professors (known as the project’s co-investigators). • Professors can manage and/or work on multiple projects. • Each project is worked on by one or more graduate students (known as the project’s research assistants). • When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one. The FDs for the above requirements are given as, • PSSN →…
With respect to union compatibility, in what situation does that make sense?
A company database needs to store information about employees (identified by ssn, with salary and phone as attributes), departments (identified by dno, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company. Draw an ER diagram that captures this information.

In campus management system, one of the work flows has following description; A Student submits admission form to apply for admission in university. The form is evaluated and approved forms are shortlisted. Shortlisted students are invited for interview. After interview of students, selected forms are stored in database. You are required to draw a Data Flow Diagram of above scenario.
How can you make sure your model has what it requires?Why might problem statements benefit from data modelling techniques?
The contrasting characteristics of overlapping and disjoint constraints are the focus of this description.
1. Which of the studied data structures in this course would be the most appropriate choice for the following tasks? And Why? To be submitted through Turnitin. Maximum allowed similarity is 15%. a. A training institute needs to maintain a database of 2000 identification numbers of trainees who received an ICDL certification. The goal is to find rapidly whether or not a given ID is in the database. Ordering information among the identification numbers is not important; speed of response is very important; efficient use of memory is also important, but not as important as speed of response. b. A large fixed content of data needs to be maintained. It is sorted and the admin needs to search for and retrieve existing items, but no new/existing items will be inserted/deleted. You may assume that the data can fit inside the memory of the computer. c. A transposition table is a cache of previously seen positions in a game tree generated by a computer game playing program. If a position recurs…
ProblemIn this problem, we wish to design and build components of an assessmentmanagement system using gRPC. The system has three user profiles: learner,administrator and assessor. Note that each user should have a unique identifierin the system. A learner registers for courses, submits assignments for eachassessment of each course he/she registered for, and finally checks his/her result.An administrator adds new courses and sets the number of assessments for eachcourse and the assessment weights. He/she also assigns assessors to each course.Finally, an assessor allocated for a course assesses the assignments submitted.In short, we have the following operations:• create_courses, where an administrator creates several courses, definesthe number of assignments for each course and sets the weight for eachassignment. This operation returns the code for each created course. It isbidirectional streaming;
May I ask for part (iii), user -> nonregistered and user -> registered is in which NF? it wasn't clear. The follow up answer was for a different question.
Draw an ER diagram for the EMU Slimming Center based on the specification given below. Case Study 01 A wedding hall (Shadi Hall) organizes different types of functions for its customers. Each function is hosted (owned) by exactly one customer. A customer may host many functions. There are many employees working at the company. Before each function date, the administrations of the wedding hall calls a meeting of relevant employees to finalize the arrangements of the function. Each meeting belongs to exactly one function. Comments/suggestions of each employee in the meetings and the decisions of the meetings are also recorded. Instructions: • Identify the relationship between Entities (clearly showing the cardinality and participation)
