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.

Forward slashes (/) are used for web address and backslashes (\) are used for file paths is the following correctly describes rules for setting up a Web file structure.
<u>Explanation:</u>
For a way to a nearby document on a Windows machine, utilize the backslash. For a way to a web asset or record situated on a UNIX based machine (incorporates Macs, Linux), use a slash.
The explanation .NET's URI utilizes forward slashes is on the grounds that it's arranging for use in an internet browser. at the point when a slash is utilized in a formal or casual book, it is intended to show the word or. The models show the importance of the forward-slash.
Answer:
return instruction used to return a value from a function.
Explanation:
Function is a block of statement which perform the special task.
Syntax for define a function:
type name(parameter_1, parameter_2,...)
{
statement;
return variable;
}
In the syntax, type define the return type of the function. It can be int, float, double and also array as well. Function can return the array as well.
return is the instruction which is used to return the value or can use as a termination of function.
For return the value, we can use variable name which store the value or use direct value.
