1. In your own words, describe the difference between Microsoft Word and Google Docs.
2. Identify examples for when you would use each program in the workplace.
3. Which of the programs do you currently use the most. Why?
Consider the following database for some store:
Customers (cid, cname, city, discount)Agents (aid, aname, city, percent)Products (pid, pname, city, quantity, price)Orders (ordno, mon, cid, aid, pid, qty, dollars)
The relation Customers records the ID (cid), name (cname), location (city) of each customer and a discount percentage (discount) for this customer.
The relation Agents records the ID (aid), name (aname), location (city) of each agent and a transaction fee (percent) charged by this agent.
The relation Products lists the ID (pid), name (pname), location (city), quantity and price of available products.
And finally, the relation Orders contains a unique order number (ordno), the month (mon), customer (cid), agent (aid), product (pid), quantity (qty) of each order as well as the total value (dollars) of the transaction.
1. Express the following query in SQL
(a) List customers (names) who do not have discounts but purchased at least one product of price greater than $50.
(b) Find…
Consider the following relational schema and briefly answer the questions that follow:
Emp(eid: integer, ename: string, age: integer, salary: real)
Works(eid: integer, did: integer, pct_time: integer)
Dept(did: integer, budget: real, managerid: integer)
a. Define a table constraint on Dept that will ensure that all managers have age > 30.
b. Write SQL statements to delete all information about employees whose salaries exceed that of the manager of one or more departments that they work in. Be sure to ensure that all the relevant integrity constraints are satisfied after your updates.

- Consider the following relations: Student(snum: integer, sname: string, rmajor: string, level: string, age: integer) Class(cname: string, meets_at: time, 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 one record per student-class pair such that the student is enrolled in the class. 2. Express each of the following integrity constraints in SQL unless it is implied by the primary and foreign key constraint; if so, explain how it is implied. If the constraint cannot be expressed in SQL, say so. For each constraint, state what operations (inserts, deletes, and updates on specific relations) must be monitored to enforce the constraint. (a) Every faculty member must teach at least two courses. (b) Every student must be enrolled in the course called 'Math101'. (c) A student cannot add more than two courses at a time…arrow_forwardConsider the following relational schema. An employee can work in more than one department; the pct_time field of the Works relation shows the percentage of time that a given employee works in a given department. Emp(eid: integer, ename: string, age: integer, salary: real) Works(eid: integer, did: integer, pct_time: integer) Dept(did: integer, budget: real, managerid: integer) Write the following queries in SQL: a. Print the name of each employee whose salary exceeds the budget of all of the departments that he or she works in. b. Find the enames of managers who manage only departments with budgets larger than $1 million, but at least one department with budget less than $5 million.arrow_forwardConsider the following schema: Suppliers(sid: integer, sname: string, address: string) Parts(pid: integer, pname: string, color: string) Catalog(sid: integer, pid: integer, cost: real) The Catalog relation lists the prices charged for parts by suppliers. Write the following queries in SQL: a. Find the sids of suppliers who charge more for some part than the average cost of that part (averaged over all the suppliers who supply that part). b. Find the sids of suppliers who supply a red part or a green part. c. For every supplier that supplies a green part and a red part, print the name and price of the most expensive part that she supplies.arrow_forward

Write each of the following queries in SQL.(Additional queries using the same schema are listed in the exercises for Chapter 4) a. Identify the routes that can be piloted by every pilot who makes more than $100,000. b. Print the name and salary of every nonpilot whose salary is more than the average salary for pilots. c.
