PART 1The goal of this assignment is to design a conceptual schema using the (E)ER Data model.(E)ER data modelDesign a schema that incorporates the specification described below as efficiently as possible.You should submit a written diagram of your schema design using the notation given in theclass. In this diagram, indicate all the classes, subclasses, relationships (weak & strong),relationship cardinalities and degrees, total participations, attributes, and primary keys. Inaddition, specify whether each attribute is single-valued or multi-valued, stored or derived, andatomic or composite. In your design, you can make and state reasonable assumptions if they arenot specified in the specification.Design SpecificationYelp is a local business directory service and review site with social networking features. Itallows users to give ratings and review businesses. You are going to design the database systemfor Yelp (www.yelp.com). It should store and manage the following information but…
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.

Complete the ERD below by dragging the ends of crows feet and the specialization hierarchy symbols to their correct location. The XYZ Company has a motor pool and wants to track scheduled and unscheduled maintenance to each of the vehicles in its fleet. Each vehicle is assigned a unique unit number that will be used on all paperwork and is displayed on the vehicle. In addition to the unit number all vehicles have a unique Vehicle Identification Number (VIN) that is a long and complex string of letters and numbers, and all vehicles belong to one of three types "T" for trucks, "R" for trailers, and "A" for automobiles. For trucks, we need to know the Gross Vehicle Weight (GVW) and the type of trailer hitch (if it has one). For trailers, we need to know their length, the maximum weight allowed, the type of trailer (Van, Reefer, Low Boy, Flat…), and the required hitch type. For automobiles, we need to know how many adults it will seat, its color, and if it is a "4 wheel drive". Maintenance…
