For each of your constraints in (a)and (b), describe in one sentence why your constraint is necessary.

1. Consider the following relations:Student (snum: integer, sname: string, major: string, level: string, age: integer)Class (name: string, meets at: string, room: string, fid: integer)Enrolled (snum: integer, cname: string)Faculty (fid: integer, fname: string, deptid: integer)The meaning of these relations is straightforward; for example, Enrolled has onerecord per student-class pair such that the student is enrolled in the class. Level is atwo character code with 4 different values (example: Junior: A Level etc)Write the following queries in SQL. No duplicates should be printed in any of theanswers.i. Find the names of all Juniors (level = A Level) who are enrolled in a classtaught by Prof. Kwizeraii. ii. Find the names of all classes that either meet in room R128 or have five ormore Students enrolled.iii. Find the names of all students who are enrolled in two classes that meet atthe same time.
Relational model: In the personal model, data are prearranged in tables, which contain of table. A data in a table is called fields. Fields in a db table are also referred as qualities of a db object. A group of related fields are called as a record, which I also called as db object or entity. A group of records are called a table. Keys in a relational db table refer to a key field. To identify each record in a table, there must be at least one data field that should be unique. That is, a corresponding data field of every record should be unique. Therefore, key field is used to identify the unique record from a collection of records.
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.

Q4: Design a database for an airline. 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. Your design should include a set of relational schemas, and a list of constraints, including primary-key and foreign-key constraints. Please note that an E-R diagram is not required.
//Last three parts not answered before You are working with a database that stores information about suppliers, parts and projects. The Supply relation records instances of a Supplier supplying a Part for a Project. The schema for the database used in this question is as follows: ( primary keys are shown underlined, foreign keys in bold). SUPPLIER (SNo, SupplierName, City) PART (PNo, PartName, Weight) PROJECT (JobNo, JobName, StartYear, Country) SUPPLY (SNo, PNo, JobNo, Quantity) Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc or the words ‘PROJECT’, ‘RESTRICT’ etc . do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the quantity of parts supplied on JobNo 4745. List the weight of the Part named “Left-handed screwdriver”.

Consider the following relation: CAR_SALE (Car_id, Option_type, Option_listprice, Sale_date, Option_discounted price). This relation refers to options installed in cars (e.g., cruise control) that were sold at a dealership, and the list and discounted prices of the options. If Carl D → Sale_date and Option_type → Option_listprice and {Carl D, Option_type} → Option_discountedprice, a) Argue using the generalized definition of the 3NF that this relation is not in 3NF. b) Argue from your knowledge of 2NF, why it is not even in 2NF.
If you sell a house more than once, it is treated as different "property" for each sale. Draw an entity-relationship diagram and write a database design outline. Q2. Law Office: You are trying to automate the records for your uncle's law firm. Multiple attorneys work for the firm, and for each of them you want to store their first name, last name, date hired, hourly billing rate, and date promoted to partner (blank if the attorney is not a partner). Each attorney has multiple cases, which is identified by a unique "docket number". Each case has a name and description, is worked on by only one attorney, and involves a single client. For each client, you want to store a first name, last name, middle name, phone number, address, city, state, and zip code (assume you do not have a zip-code table). Finally, you want to keep track of the billable hours spent on each case. For a single case, this comprises information that looks like Hours Billed Date 2/24/2005 Description Prepare brief…
