Pick the correct statements regarding cell references.

shusha [124]

Statement two and three is correct.

Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.

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%)

What is one major structural difference between a decision structure (such as a decoder) and a storage structure (such as an RS

Andrej [43]

Answer:

B. The storage structure requires a clock input.

Explanation:

Logic circuits are circuits in electronics that give output based on the logic gate principle and its inputs. It can be a sequential logic circuit or a combinational logic circuit.

Decoders RS latches are combinational logic circuits because they both comprise of a combination of several sequential circuits to make their systems. The difference between decoders and RS latches is that the RS is a storage structure which is made up of flip-flops which require a clock input
