Expert Solution & Answer
Chapter AE, Problem AE1.2
Explanation of Solution
a.
- Mention a query as a manager of Denver plant to know the amount of time employees are spending on special project:
To know the amount of time employees are spending on special project can be answered directly by the Denver Sum query which is accurate, relevant and sufficient. The answer to amount of time employees are spending on special project can also be answered by the Plant Sum query for Denver and the other two plants.
- Mention a query as a manager of Reno plant to find the amount of time employees are spending on special projects:
There is not a single query that answers the amount of time employees are spending on special project directly; however, Plant sum query can answer this question. Plant sum query is accurate and sufficient but adds extra information as it calculates the total hours for Denver and Chicago plants also.
- Mention a query to know how much time employees are spending on Quota Computation project:
The total amount of time employees are working on Quota computation project can be calculated using Sorted Query 1. These query lists the total hours worked by employees in quota computation project in Chicago project which can be manually added to find the total hours spend on quota computation project by Chicago plant employees. Here the data is sufficient but needs manipulation to produce relevant result and hence accuracy is questionable. The data is sufficient as there is information in the query that is not really needed.
- Mention a query to find the number of hours worked by employees in the quota computation project in all three plants:
To find the number of hours worked by employees in the quota computation project in all three plants cannot be answered directly by any query...

One of the tables that was produced as a consequence of the DBA denormalizing some of the data in the TAL Distributors database so that it could function more effectively is formatted as follows: Which field or fields in the Customer table (which includes CustomerNum, CustomerName, Street, City, State, PostalCode, Balance, CreditLimit, RepNum, and RepName) are responsible for the table no longer being in third normal form? In this particular instance, what would the normal form of the denormalized table be?
Use the information below to answer the question.
What types of additional information and constraints would you like to represent in the schema?
Think of several users of your database, and design a view for each.
CREATE TABLE USER1
(SSN INT NOT NULL,
FNAME VARCHAR2(20),
M VARCHAR(1),
LNAME VARCHAR2(20),
ADDRESS VARCHAR2(100),
PHONE INT,
AGE INT,
SEX VARCHAR(1),
JOBTYPE VARCHAR2(30),
ASTYPE VARCHAR2(30),
ETYPE VARCHAR2(30),
SHIFT VARCHAR2(20),
POSITION VARCHAR2(30),
AP_NAME VARCHAR2(100),
PRIMARY KEY(SSN),
FOREIGN KEY(AP_NAME) REFERENCES AIRPORT(AP_NAME) ON DELETE CASCADE);
INSERT INTO USER1(SSN, FNAME, M, LNAME, ADDRESS, PHONE, AGE, SEX, JOBTYPE, ASTYPE, ETYPE, SHIFT, POSITION, AP_NAME)
VALUES(123456789,'LINDA','M','GOODMAN','731 Fondren, Houston,…
this is an ITSE 2356 COURSE ,we use Iggy fernandez and Bob Bryla as a reference :
Case: As of late, there seems to be a perpetual problem with current database table size growth causing performance problems, -- in that you are at a point of daily tablesize management.
Task: Develop and preapre a plan that will create a reporting process to monitor database growth.(as part of your submittal - write the suggested SQL queries). Again, this shoud be no less one typed word file. Also recommend the use of Spooling or some other Oracle print process for query submital.

I need to write a procedure that accepts an instructor ID as input. The procedure calculates the total number of course sections taught by that instructor, and adds a tuple to the instructor_course_nums table consisting of the instructors ID number, name, and total courses taught - call these attributes: ID, name, and tot_courses. 2. If the instructor already has an entry in the table, then the procedure makes sure the total number of courses taught in the instructor_course_nums table is up-to-date. Here is what I have that answers the first part of the question: CREATE TABLE instructor_course_nums ( id varchar (10), name varchar (30), tot_courses integer, CONSTRAINT instructor_course_nums_pkey PRIMARY KEY (id)); CREATE OR REPLACE PROCEDURE Student_00_insCourseNumsProc(ID varchar(10), name varchar (25), tot_courses…arrow_forward
