Explanation:

As noted in question that a terminated employee comeback in office and installed some malicious script on a computer that was scheduled to run a logic bomb on the first day of the following month. And, that script will change administrator passwords, delete files, and shut down over 100 servers in the data center.

The following problem can be with that account

Unauthorized user access and privileges

The user may be given unauthorized access to system resources. If a user has unauthorized access to system resource then he can modify or destroy the system function easily.

The firewall may be disabled to detect the malicious script

The firewall should be enabled to detect such types of attack from unauthorized access to the system

Role

Since the bank wants to streamline their operations for the receiving and processing checks while also enhancing the solution to recognize signs of potential check fraud, then the machine learning can be used.

Consider the following relation:CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)Assume that a car may be sold

GalinKa [24]

Answer:

The answer to this question can be given as:

Normalization:

Normalization usually includes the division of a table into two or more tables as well as defining a relation between the table. It is also used to check the quality of the database design. In the normalization, we use three-level that are 1NF, 2NF, 3NF.

First Normal Form (1NF):

In the 1NF each table contains unique data. for example employee id.

Second Normal Form (2NF):

In the 2NF form, every field in a table that is not a determiner of another field's contents must itself be a component of the table's other fields.

Third Normal Form (3NF):

In the 3NF form, no duplication of information is allowed.

Explanation:

The explanation of the question can be given as:

Since all attribute values are single atomic, the given relation CAR_SALE is in 1NF.
Salesperson# → commission% …Given Thus, it is not completely dependent on the primary key {Car#, Salesperson#}. Hence, it is not in 2 NF.

The 2 NF decomposition:

CAR_SALE_1(Car#, Salesperson#, Date_sold, Discount_amt)

CAR_SALE_2(Salesperson#, Commission%)

The relationship in question is not in 3NF because the nature of a transitive dependence occurs
Discount_amt → Date_sold → (Car#, Salesperson#) . Thus, Date_sold is neither the key itself nor the Discount amt sub-set is a prime attribute.

The 3 NF decomposition :

CAR_SALES_1A(Car#, Salesperson#, Date_sold)

CAR_SALES_1B(Date_sold, Discount_amt)

CAR_SALE_3(Salesperson#, Commission%)
