الرجاء المساعدة في حل واجب الdatabase

The Center of Astronomy Studies works on a huge database that contains data about celestial objects (moons, planets, stars, galaxies, etc.), which are stored in a powerful server machine and accessed through the Internet.

The scientists in this center need to execute large transactions and to analyze big amount of data, so, they are now equipped with a client machines which have exactly the same performance of the server.

Question 1. Is it still making sense to keep this data in client/server system? Why?

Question 2. What is the benefit if this center when using data-server architecture?

Considering that the center implements a client/server architecture based on data-server. When a scientist requests the data about a star to be analyzed, there is a great chance for the same scientist (or other scientist working on the same client machine) that he requests data about other stars with same the same size or age belonging to the same galaxy.

Question 3. What is the most suitable shipping approach for this type of transactions? Explain how it will be performed.

Question 4. Considering the shipping approach from your answer to the previews question, the using of the data caching technique will be highly appreciated in such situation, why?
