Consider the following query against the RVH
database . Create secondary key indexes to optimize the performance of this query. State any assumptions.For each treatment performed in the past two weeks, list the physicians performing the treatment (grouped by treatment) and the number of times each physician performed that particular treatment on that particular day. Order the list by treatment ID and by reverse chronological order for each treatment ID.
Suppose the date treatment performed was not entered. What procedures are required to handle the missing data?
Are there opportunities for horizontal or vertical partitioning of the
Besides the 3NF relations, what additional types of information are required to create a physical
