Can a user process be given permission to access shared memory in a
Step by step
Solved in 3 steps
- Oftentimes, database systems are made up of processes (also known as threads) that communicate with one another via interacting with shared memory resources.Access to the shared memory space is restricted in what way, if at all.When it comes to serializing access to data structures in shared memory, is two-phase locking the most acceptable technique? Your response should be supported by reasoning.Database systems are often comprised of processes (also known as threads) that communicate with one another by interacting with shared memory resources.What, if any, access to the shared memory area is controlled.Is two-phase locking the most acceptable strategy for serializing access to data structures in shared memory? Your answer should be backed up by logic.In the case of databases, is it acceptable to make a user process capable of accessing the shared memory of the system? Describe the steps you took to arrive at your conclusion.
- Can a user process be given permission to access shared memory in a database? Justify your reasoning for accepting this conclusion.The limitations of the file-based approach in database systems is attributed to two factors. briefly describe themDatabase systems are often made up of processes (also known as threads) that interact with shared memory resources to communicate with one another.What, if any, restrictions are placed on access to the shared memory space?Is two-phase locking the most acceptable strategy for serialising access to data structures in shared memory? Your answer should be backed up by logic.
- What are the primary distinctions between a local-area network and a wide-area network when it comes to accessing a distributed database?What are the main distinctions between a local-area network and a wide-area network when it comes to building a distributed database?How does the "isolation vs. latency" trade-off play out in high-concurrency database systems?
- What are the potential problems that can occur in a multi-user database system without proper concurrency control mechanisms?Implementers of database systems have given much greater attention to the ACID characteristics than those of file systems. Why is it possible that this is the case?What are the primary differences between a local-area network and a wide-area network in terms of constructing a distributed database?
