1.   Discuss the four processes that contribute to a data warehouse.

2.   What is the importance of Backup and Archive in the event of system failure?

3.   List down at least 3 ways in improving or optimizing database queries.

4.   DMMMSU is planning to implement a uni-wide enrollment system where each campuses will be maintaining its own database but at the same time data will still be accessible even if its own database server is offline. This is by accessing its data from a distributed database house in other campuses. Given this scenario, make a plan by identifying the tables that will be housed in data mart and data warehouses. Identify the facts and dimension table in the database. If partitioning is required, show how the database table will be partitioned.
