Read Scnerio carefully : Make a Propose and optimal database design in RDBMS for a super store. In which clients came and can purchase products according to their likes and dislikes. Super store have same products of different companies. In the end client received a receipt of their purchase from counter he/she go for bill. Database also save records of stock according to FIFO system. Required to define Entities and their attributes Attributes Types Each Attribute Required Define keys of each entity Define relationship between the entities.
The following is the relation notation of a database table in 1NF ORDER(CustNum, CustFN, CustLN, OrderNum, OrderDate, ProdNum, ProdDesc, Qty, UnitPrice) The functional dependencies are given below: CustNum → CustFN, CustLN OrderNum - OrderDate, CustNum, CustFN, CustLN ProdNum → ProdDesc OrderNum, ProdNum -> UnitPrice, Qty Use the functional dependencies above to answer the following questions. Don't not make additional assumptions and functional dependencies. A. List all partial dependencies in the relation only (if any) using the dependency numbers. Don't write the dependencies in X->Y format, just indicate their numbers (which are listed on the left side, i.e., 1, 2, 3, 4). Indicate only the dependencies that you think are partial. B. Identify and show the 2NF. Show primary keys and foreign keys references. Use relational notation (show references). Write down all relations and their references below. C. List all transitive dependency in your answer to question b (if any)…
The dependency diagram indicates that authors are paid royalty for each book they write for a publisher.The amount of royalty can vary by author,by book ,and by edition of the book. a.Based on the dependency diagram,create a database whose tables are atleast in 2NF showing the dependency diagram for each table. b.Create a database whose tables are atleast in 3NF,showing the dependency diagram for each table.
Task #1 – Identification of dependencies We learned about two types of functional dependencies, Partial Dependency and Transitive Dependency, and they are critical clues for the identification of tables. In this task, we will practice how to identify the two types of dependencies, so that we can improve the results to new tables. Below is a list of attributes of a dataset. However, the attributes still have some functional dependencies, which means you can create more tables by separating some field(s). Order_ No Product_ No Product_ Description Product_ UnitPrice Customer_No Customer_ Phone Customer_ Address Order_ Date Shipping_ Address Order_ Qty Which partial dependency does this dataset have? Identify the partial dependency using the format in the example below. Example) Partial Dependencies: (ProjectNum ? Proj_Name) (Emp_Num ? Emp_Name, Job_Class) Then, which transitive dependencies does this dataset have? Identify the transitive dependencies…
Given the database schema with the following relations: STUDENT (id_stud, name_stud) LECTURER (id_lect, name_lect) SUBJECT (id_subject, id_lect, name_subject, credits, id_room) ROOM (id_room, no_room) ENROLL (id_stud, id_subject) Create an algebraic relation for: a. Displays all names of lecturers who teach the subject with a total of 4 credits b. Displays all no_room with the student name "Eko" c. Displays all data in the form of student id, student name, name of the course followed and the name of the lecturer who taught the subject name "Database" From the database schema and the questions above, create an appropriate SQL query for each of these statements above.

Consider the following relations for a simple airport databas Hangars (hangNo, capacity, location, status) AirplaneTypes (Model, capacity, weight) Airplanes (regNo, model, hangNO) Owners (owner, name, address, phone, ssn) Owns (regNo, ownID, startedDate) There are four foreign keys for this database: 1. The attribute hangNo of the relation Airplanes that references the relation Hangars, 2. The attribute model of the relation Airplanes that references the relation AirplaneTypes, 3. The attribute regNo of the relation Owns that references the relation Airplanes, and 4. The attribute ownID of the relation Owns that references the relation Owner. Q1: Write SQL statements to define the above relation Hangars. You should choose a suitable data type and/or daya size for each column and be sure to declare appropriate integrity constraint(s). Q2. Which of the following SQL statements is used to define the above relation Airplanes? Ensure the data type and size for each attribute are…

In the event where both relations are not physically sorted but have an index on the characteristics being merged, an appropriate hybrid merge-join mechanism should be developed.
