What is the drawback of parallel database architecture Mcq?
Disadvantages: Higher degree of parallelism (more number of concurrent operations in different processors) cannot be achieved due to the reason that all the processors share the same interconnection network to connect with memory.
What is parallel database architecture?
A parallel database is designed to take advantage of such architectures by running multiple instances which “share” a single physical database. In appropriate applications, a parallel server can allow access to a single database by users on multiple machines, with increased performance.
What are the benefits of parallel databases?
The main advantage to parallel databases is speed. The server breaks up a user database request into parts and dispatches each part to a separate computer. They work on the parts simultaneously and merge the results, passing them back to the user.
How is parallel database system different from distributed database system mention the advantages and disadvantages of distributed database system?
A parallel DBMS is a DBMS that runs across multiple processors and is designed to execute operations in parallel, whenever possible….Difference between Parallel and Distributed databases.
| Parallel Database | Distributed Database |
|---|---|
| Parallel databases are generally homogeneous in nature | Distributed databases may be homogeneous or heterogeneous in nature. |

| c. | Each site must have the same storage capacity. |
| d. | Each transaction may proceed without coordination across the network. |

What are the different architectural models of parallel database?
Parallel database architectures can be broadly classified into three categories: shared memory, shared disk, and shared nothing. An important question, however, is which architecture should be used for a specific database application. Each architecture has its strengths and weaknesses.
What are the advantages of a parallel system over a traditional system?
Benefits of parallel computing. The advantages of parallel computing are that computers can execute code more efficiently, which can save time and money by sorting through “big data” faster than ever. Parallel programming can also solve more complex problems, bringing more resources to the table.
What are the disadvantages of parallel system?
Disadvantages. The cost of implementation is very expensive because of the need to operate the two systems at the same time. It is a great expense in terms of electricity and operation costs. This would be prohibitive with a large and complex system.
What are advantages and disadvantages of distributed database system architecture?
Distributed Database Advantages and Disadvantages
| Advantages | Disadvantages |
|---|---|
| Modular development | Costly software |
| Reliability | Large overhead |
| Lower communication costs | Data integrity |
| Better response | Improper data distribution |
Which is the main disadvantage of replication?
Which of the following is a disadvantage of replication?
| 1) | Each transaction may proceed without coordination across the network. |
|---|---|
| 2) | If the database fails at one site, a copy can be located at another site. |
| 3) | Reduced network traffic |
| 4) | Each site must have the same storage capacity. |
| 5) | NULL |
What is the disadvantage of replication?
DISADVANTAGES OF DATA REPLICATION – More storage space is needed as storing the replicas of same data at different sites consumes more space. Data Replication becomes expensive when the replicas at all different sites need to be updated. Maintaining Data consistency at all different sites involves complex measures.
