Expert Solution & Answer
Chapter 8, Problem 1RQ
Explanation of Solution
“WHERE” clause:
- The “WHERE” clause is used to limit the number of rows.
- The “WHERE” clause is used for checking a condition while fetching the data from a single table or by joining with multiple tables.
- When the given condition is satisfied, the specific value is returned from
database . - By using “WHERE” clause we have to filter specific records from table.
- “WHERE” clause is used in “SELECT”, “UPDATE” and “DELETE” statements.
Therefore, the “WHERE” clause is used to limit the number of rows returned.

How would I go about creating this computer database in MariaDB with sql?
Create a database name "dbXXXXXX" Select the database using the "use [database name]" command.
Now you are in the database.
Based on the above schema from Enrolment System database, create all the tables with the last 6 digits of "123456", then the table name for table Lecturer should be "123456_Lecturer". Refer to basic SQL lecture note to create table that has primary keys and Foreign Keys. Provide the datatype of each attributes.
Add a column called "Department" with datatype "VARCHAR(12)" to the table "Lecturer". Shows the metadata of the updated "Lecturer" table. (Use Describe command)
Drop the "Department" column from the table "Lecturer", and show the metadata of the updated "Lecturer" table.
Insert three (3) data to each of the table in the tables created.
Note: If you have foreign key issues, please disable foreign key constraints before inserting the data, see below

- CSE330 Discrete Mathematics 1. In the classes, we discussed three forms of floating number representations as given below, (1) Standard/General Form, (2) Normalized Form, (3) Denormalized Form. 2. Let ẞ 2, m = 6, emin = -3 and emax = 3. Answer the following questions: Compute the minimum of |x| for General and Normalized form (a) Compute the Machine Epsilon value for the General and Denormalized form. If we change the value of emax to 6 then how will it affect the value of maximum scale invariant error for the case of Normalized form?

- Compare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forwardI need to resolve the following....You are trying to convince your boss that your company needs to invest in a license for MS-Project (project management software from Microsoft) before beginning a systems project.
