Data Mart is a smaller amount of data that is collected from a data warehouse.
Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.
Answer:
13: 1101
5: 0101
10: 1010
2: 0010
Explanation:
The binary system, on the other hand, is a base-2 number system. That means it only uses two numbers: 0 and 1. When you add one to one, you move the 1 one spot to the left into the twos place and put a 0 in the ones place
what is done with the dice is to have an example of how binary numbers are made until 15
Answer:
Answer is A. One.
Refer below.
Explanation:
A data flow cannot go directly back to the same process it leaves. There must be at least one other process that handle(s) the data flow, produce(s) some other data flow, and return(s) the original data flow to the beginning process.

See Explaination
Explanation:
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class GradesAverage {
private static int checkNum(String num) {
int tmpNum;
try {
tmpNum = Integer.valueOf(num);
} catch(IllegalArgumentException e) {
System.out.println("You did not enter an integer.");
return -1;
}
return tmpNum;
}

if(num>=0 && num<=100) {
return true;
}
