sveticcg [70]

Answer: Naming the function

Explanation:

The first item for defining the function is the naming of the function. In the function, the first line is known as header and rest of the function is known as body of the function.

The function name is the first step while defining the proper function as we can define the actual function name on which the program are rest based.

We can define a function from which the each value from the set of the components are basically associated with the second component in that particular function.

Consider the following relation: CAR_SALE (Car#, Date_sold, Salesman#, Commision%, Discount_amt Assume that a car may be sold by

Nady [450]

Answer:

See explaination

Explanation:

The given relation is:

CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)

Primary key: {Car#,Salesperson#}

We will first check whether the relation is in 1NF.

A relation is said to be in the 1st Normal form(1NF) if all the columns in the relation have atomic values. In this case, the relation is in 1NF.

A relation is said to be in the second normal form(2NF) if it satisfies the condition that all non keys are completely dependent on the primary key and just a part of the primary key.

In the case of the CAR_SALE relation, the Commission% depends only on the Salesperson# and not on the combination of Car# and Salesperson#. This means that the given relation is not in 2NF. To satisfy 2NF, we make two relationships as given below:

SALE_DETAIL(Salesperson#, Commission%)

and CAR_SALE(Car#, Date_sold, Salesperson#, Discount_amt)

Now both the relations are in 2NF.

For a relation to be in 3NF, no non-key should be functionally dependent on another non key.

In the case of the CAR_SALE relation, it is specified that the Date_sold field determines the Discount_amt. Therefore the modified CAR_SALE is not in 3NF.

To satisfy 3NF, we seperate the non key and the dependent non key and create a different table.

Final Relations:

SALE_DETAIL(Salesperson#, Commission%)

Discount_Detail(Date_Sold, Discount_Amt)

CAR_SALE(Car#, Date_sold, Salesperson#)

Svetach [21]

Answer:

The correct answer to the following question will be Option A (Bank).

Explanation:

Sometimes on a motherboard, the memory modules are grouped into different groups and that each group is named as a branch. Furthermore, the term "bank" may be used loosely to describe a basic computing data storage area. When the record is stored in the database it can be accessed at a specific time by the user.
Because the 486 is a 32-bit processor and a 30-pin SIMM is 8-bit, four SIMMs (8x4=32) is called a bank when installing memory on an 80486 processor computer; Install four 16 MB SIMMs when upgrading to 64 MB.

Therefore, Option A is the right answer.
