When data are normalized, attributes in the table depend only on the secondary key?

Answers

Answer 1
Answer: False
They depend only on the secondary key and not the primary key. Normalization analyzes and reduces a relational database toits streamlined form for min redundancy, and data integrity. A primary keyuniquely identifies all table records. They typically appear as columns in arelational DB.

Keeping track of these files is a big job. To perform this task, the OS makes an index of all the files stored on the computer. This index is called a File Allocation Table (FAT). The OS updates the FAT every time a file is created, renamed, moved, or deleted.

The answer is Query Design.

(JAVA PLS)Your job in this assignment is to write a program that takes a message as a string and reduces the number of characters it uses in two different set ways. The first thing your program will do is ask the user to type a message which will be stored as a String. The String entered should be immediately converted to lowercase as this will make processing much easier. You will then apply two different algorithms to shorten the data contained within the String.

Algorithm 1

This algorithm creates a string from the message in which every vowel (a, e, i, o, and u) is removed unless the vowel is at the very start of a word (i.e., it is preceded by a space or is the first letter of the message). Every repeated non-vowel character is also removed from the new string (i.e., if a character appears several times in a row it should only appear once at that location). So for example the string "I will arrive in Mississippi really soon" becomes "i wl arv in mssp rly sn".

After applying this algorithm, your program should output the shortened message, the number of vowels removed, the number of repeated non-vowel characters removed, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.

Algorithm 2

This algorithm creates a string by taking each unique character in the message in the order they first appear and putting that letter and the number of times it appears in the original message into the shortened string. Your algorithm should ignore any spaces in the message, and any characters which it has already put into the shortened string. For example, the string "I will arrive in Mississippi really soon" becomes "8i1w4l2a3r1v2e2n1m5s2p1y2o".

After applying this algorithm, your program should output the shortened message, the number of different characters appearing, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.

Sample Run 1
Type the message to be shortened
This message could be a little shorter

Q.3) Option b) RBAC

Q.4) Option c) DAC

Q.5) Option b) Management

What is MAC ?

The ability of individual resource owners to allow or refuse access to resource objects in a file system is constrained by the security measure known as mandatory access control (MAC).

What is a biometric device ?

An authentication and security identification tool is a biometric gadget.

What is RBAC ?

Role-based access control, often known as role-based security, is a method for only allowing authorized users to access a system.

What is DAC ?

The idea behind discretionary access control is to limit access to things based on who the subject is.

Therefore, MAC, biometric device, RBAC, DAC and Management access control sets are some of the measures for network security and access control.
