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:
loop
Explanation:
Loop is the one which is used to execute the specific statement again and again until the condition is true.
In the programming, there are 3 basic loop used.
1. for loop
<u>Syntax:</u>
for(initialization, condition, increment/decrement)
{
statement;
}
the above statement execute until the condition in the for loop true when it goes to false, the loop will terminate.
2. while loop
<u>Syntax:</u>
initialization;
while(condition)
{
statement;
increment/decrement;
}
it is work same as for loop and the increment/decrement can be write after or before the statement.
3. do while
syntax:
initialization;
do
{
statement;
increment/decrement;
}while(condition);
here, the statement execute first then, it check the condition is true or not.
so, if the condition is false it execute the statement one time. this is different with other loops.
Answer:
ElectroMyCycle, LLC.
The research I will do before my initial meeting with the executive management team will be to find out the following:
4. Client’s suppliers and customers
5. Products and services offered
Explanation:
My research will concentrate on the types of products and services that ElectroMyCycle is offering its customers and raw materials that it purchases from the suppliers, because the network assets are being installed to enhance business transactions between ElectroMyCycle and its customers and suppliers. And as the company is expanding with more suppliers and customers, more products and services, the network configuration will be built around these stakeholders.

Answer:
Assessing opportunity cost involves <u>making choices and dealing with consequences.</u>
Explanation:
Opportunity cost means that, the cost to gain something with some consequences. If there are multiple opportunities in front of you and you have to analyze or assess each opportunity. In this assessment you have to assess the consequences of all choices or opportunities. After assessing all the opportunities you will select the opportunity in which you have more gain and less consequences.
So we can say that, while assessing different opportunities, we have to make choices and dealing with consequences.
