Data type 1.) Database Design : Take a crack at designing a simple database for 'A Small Dentist Office'. To keep it simple, please exclude any financial or billing information. So build a simple database that keeps track of patient information and appointments. Keep this very simple, maybe 4 tables. Part I: First determine the entities. The entities will be the tables. For example in an employee database the entities might be: an Employee, a Dept. These would then become the tables...the Employee table and the Dept table. Once you have come up with your 4 tables, move on to Part II. Part II: Design each table. Tables must include: a. Appropriate column names b. Data type for each column c. Whether a column can be 'null’ or not d. Indicate any Primary Keys' and Foreign Keys'. e. Indicate any relationships with other tables s → DO NOT USE MSAccess to do this Assign. I would use Excel for his Assign, or you could possiblly use MS Word.

B. Art Museum Database Draw an EER diagram to keep track of information for an art museum. Assume that the following requirements were collected: (10 marks) The museum has a collection of art objects. Each art object has a unique ID, a year (when it was created, if known), a title, and a description. Art objects must be categorized based on their type. There are three main types: painting, sculpture, plus another type called other to accommodate objects that do not fall into one of the two main types. A painting has a paint type (oil, watercolor, etc.), material on which it is drawn on (paper, canvas, wood, etc.), and style (modern, abstract, etc.). A sculpture has a material from which it was created (wood, stone, etc.), height, weight, and style. An art object in the other category has a type (print, photo, etc.) And style. The museum keeps track of artist information, if known: name, date born (if known), date died (if not living), country of origin, epoch, main style, and…
Data base systmes: Design an ER schema diagram for a sport league database to keep track of the teams and games of it. The database is organized into teams. Each team has a unique name, a unique number, and particular colors. A team may have several colors. Each team plays several games. It is desired to keep track of the result of each game. A team has a number of players, not all of whom participate in each game. Each player has a unique name, a unique number, and a particular position. It is desired to keep track of the players participating in each game for each team, the performance they played in that game, and the time played by each player in each game.
“Martial Arts R Us” (MARU) needs a database. MARU is a martial arts school with hundreds of students. The database must keep track of all the classes that are offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance. Create a complete Crow’s Foot ERD for these requirements: Students are given a student number when they join the school. The number is stored along with their name, date of birth, and the date they joined the school. All instructors are also students, but clearly not all students are instructors. In addition to the normal student information, for all instructors, the date that they start working as an instructor must be recorded along with their instructor status (compensated or volunteer). An instructor may be assigned to teach any number of classes, but each class has one and only one assigned instructor. Some instructors, especially volunteer instructors, may not…
Computer Science Relational Model (Logical and Physical Schema Development) The conceptual model developed in phase 2 will be transformed into a logical and physical schema using the relational data model. The outcome of this transformation will be a relational schema. The schema should have the following components: Set of required relations All the integrity constraints Submission and Evaluation: A report consisting of the problem statement, ER diagram, relational schema And implement the database using SQL should include: All the tables properly defined /created All constraints properly defined For each table, few instances of data should be entered.
Here is the database design for the personnel data: employee(id, name, address) employeeMap(id, confidentialId) empSalary(confidentialId, salary) The role 'Clerk' would be granted SELECT, UPDATE, DELETE to employee table and granted SELECT to empSalary table. While the clerk can see salary information for any statistical analysis (e.g. average salary computation), he has no idea which employee the salary is for. The role 'Administrator' is granted rights on all three tables; using the confidentialId in the employeeMap table, she has access to salary data for individual employees too. A SQL query that the administrator can use to access all employee fields is: select e.id, e.name, e.address, es.salary from employee e inner join employeeMap m on e.id = m.id inner join empSalary s on m.confidentialId = s.confidentialId; Can you draw a database schema?

Name the entities for the library database b. Without creating a set of dependency diagrams, write the relational schema that meet 3rd NF requirements. c. Draw the Crow’s Food entity-relationship diagram for the library database.
"SUPERMARKET STOCK CONTROL SYSTEM" It is an application made for the employees in the Super Market to query the stock of the items more easily. Thanks to a single application, they will have information about the status of the items. According to the above information draw an E-R diagram (Specifiy all entities-relationships-attributes). Show (explain in detail) that the database is at least in 3rd NF.
PLZ HELP WITH THE FOLLOWING: We will assume that the Computer Science Department at a university has an agreement with the publishers to allow faculty and students to have free exclusive access to the e-books online through their website. They need you to design a database for them using the following business rules: The faculty and students (we refer to them in our system as clients) can electronically check out any book at any time. A book must have at least one author but can have more authors. An author must have written at least one book or more to be included in the system. A book may have never been checked out, but can be checked out many times by the same client or different clients over time. A client may have never checked out a book or they may have checked out many books over time. To simplify determining which client currently has a given book checked out, a M:N relationship between BOOK and CLIENT should be maintained. The information recorded for each book is book…

Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…
PART C QUESTION 1 The NAN Book Rental Shop is seeking to implement a database system for its shop. The shop has customers known as members, and a collection of books available for rental. The purpose of the system is to track membership, book inventory, and book rental activities. The following are the current system descriptions associated with NAN Book Rental Shop. For each member, the data items that need to be recorded are: a unique membership identification number, the members' name, address, phone number and the date that the members joined the shop. • When a member rents a book, the shop will record these items: the book rental date, the book return due date, the date the book was returned, and the rental fee. Each member can rent a maximum of five books at any one time and the members must return the books in two weeks time. For each book, the book's identification number, title, type and rental price must be collected and stored in the system. Sometimes books are written by…
