Answer:
The expression is :
π[cd) + π(g,h) ],[π(e,f)+π(a,b)])
We will use foreign key and primary key

<h3>What is meant by electric shock?</h3>
When a human comes into contact with an electrical energy source, they experience an electric shock. A shock is produced when electrical energy passes through a section of the body. Exposure to electrical energy has the potential to cause fatalities or absolutely no injuries.
The tangible and tangible result of an electrical current entering the body is electrical shock. The shock could be anything from a dangerous discharge from a power line to an uncomfortable but safe jolt of static electricity after walking over a thick carpet on a dry day. trauma; related topics.

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.
The correct answer is A. Only technician B is correct because I don't believe carbon is form of resistors.
