Answer:

Expert systems

Explanation:

Experts systems are known as computerized advisory programs that are used for the imitation of expert's reasoning processes when solving problems that pose a difficulty. They are usually a knowledge base that have several accumulated experience and certain rules that are used in the application of the knowledge according to the specific situation.

toThePowerOf is a method that accepts two int arguments and returns the value of the first parameter raised to the power of the
inessss [21]

Answer:

cubeVolume = toThePowerOf(cubeSide, 3)

Explanation:

The function toThePowerOf, receives two int arguments say, a and b, where a is the first argument and b is the second argument as follows:

toThePowerOf(a,b)

The function returns the first argument(a) raised to the power of the second argument (b) i.e a ^ b as follows:

toThePowerOf(a, b){

return a^b

}

In the call to the function, the first argument a, is replaced with the variable cubeSide and the second argument b is replaced with the value 3.

Hence, the returned result becomes cubeSide ^ 3 which is then stored in a variable cubeVolume as follows:

cubeVolume = toThePowerOf(cubeSide, 3)

[1] Please find all the candidate keys and the primary key (or composite primary key) Candidate Key: _______________________ Pri
AVprozaik [17]

Answer:

Check the explanation

Explanation:

1. The atomic attributes can't be a primary key because the values in the respective attributes should be unique.

So, the size of the primary key should be more than one.

In order to find the candidate key, let the functional dependencies be obtained.

The functional dependencies are :

Emp_ID -> Name, DeptID, Marketing, Salary

Name -> Emp_ID

DeptID -> Emp_ID

Marketing ->  Emp_ID

Course_ID -> Course Name

Course_Name ->  Course_ID

Date_Completed -> Course_Name

Closure of attribute { Emp_ID, Date_Completed } is { Emp_ID, Date_Completed , Name, DeptID, Marketing, Salary, Course_Name, Course_ID}

Closure of attribute { Name , Date_Completed } is { Name, Date_Completed , Emp_ID , DeptID, Marketing, Salary, Course_Name, Course_ID}

Closure of attribute { DeptID, Date_Completed } is { DeptID, Date_Completed , Emp_ID,, Name, , Marketing, Salary, Course_Name, Course_ID}

Closure of attribute { Marketing, Date_Completed } is { Marketing, Date_Completed , Emp_ID,, Name, DeptID , Salary, Course_Name, Course_ID}.

So, the candidate keys are :

{ Emp_ID, Date_Completed }

{ Name , Date_Completed }

{ DeptID, Date_Completed }

{ Marketing, Date_Completed }

Only one candidate key can be a primary key.

So, the primary key chosen be { Emp_ID, Date_Completed }..

2.

The functional dependencies are :

Emp_ID -> Name, DeptID, Marketing, Salary

Name -> Emp_ID

DeptID -> Emp_ID

Marketing ->  Emp_ID

Course_ID -> Course Name

Course_Name ->  Course_ID

Date_Completed -> Course_Name

3.

For a relation to be in 2NF, there should be no partial dependencies in the set of functional dependencies.

The first F.D. is

Emp_ID -> Name, DeptID, Marketing, Salary

Here, Emp_ID -> Salary ( decomposition rule ). So, a prime key determining a non-prime key is a partial dependency.

So, a separate table should be made for Emp_ID -> Salary.

The tables are R1(Emp_ID, Name, DeptID, Marketing, Course_ID, Course_Name, Date_Completed)

and R2( Emp_ID , Salary)

The following dependencies violate partial dependency as a prime attribute -> prime attribute :

Name -> Emp_ID

DeptID -> Emp_ID

Marketing ->  Emp_ID

The following dependencies violate partial dependency as a non-prime attribute -> non-prime attribute :

Course_ID -> Course Name

Course_Name ->  Course_ID

So, no separate tables should be made.

The functional dependency Date_Completed -> Course_Name has a partial dependency as a prime attribute determines a non-prime attribute.

So, a separate table is made.

The final relational schemas that follows 2NF are :

R1(Emp_ID, Name, DeptID, Marketing, Course_ID, Course_Name, Date_Completed)

R2( Emp_ID , Salary)

R3 (Date_Completed, Course_Name, Course_ID)

For a relation to be in 3NF, the functional dependencies should not have any transitive dependencies.

The functional dependencies in R1(Emp_ID, Name, DeptID, Marketing, Date_Completed) is :

Emp_ID -> Name, DeptID, Marketing

This violates the transitive property. So, no table is created.

The functional dependencies in R2 (  Emp_ID , Salary) is :

Emp_ID -> Salary

The functional dependencies in R3 (Date_Completed, Course_Name, Course_ID) are :

Date_Completed -> Course_Name

Course_Name   ->  Course_ID

Here there is a transitive dependency as a non- prime attribute ( Course_Name ) is determining a non-attribute ( Course_ID ).

So, a separate table is made with the concerned attributes.

The relational schemas which support 3NF re :

R1(Emp_ID, Name, DeptID, Course_ID, Marketing, Date_Completed) with candidate key as Emp_ID.

R2 (  Emp_ID , Salary) with candidate key Emp_ID.

R3 (Date_Completed, Course_Name ) with candidate key Date_Completed.

R4 ( Course_Name, Course_ID ).  with candidate keys Course_Name and Course_ID.

What file can you edit on a linux system to configure shared folders using samba?
TiliK225 [7]

/etc/samba/smb.conf is the file you can edit on a linux system to configure shared folders using samba.

<h3>What is a Linux system ?</h3>
  • A Unix-like operating system (OS) for desktops, servers, mainframes, mobile devices, and embedded devices, Linux is open source and user-developed.
  • One of the most broadly supported operating systems, it is supported on virtually all popular computing platforms, including x86, ARM, and SPARC.
  • Windows OS is a for-profit operating system, whereas Linux is an open-source alternative. In contrast to Windows, which lacks access to the source code, Linux allows users to modify the code as needed.
  • Applications, interfaces, programs, and software are all produced through Linux programming. Desktops, real-time apps, and embedded devices frequently employ Linux code.
  • Programmers can learn about the Linux kernel for free online, enabling them to use, modify, and develop Linux without restriction.
