1. For the first query, which involves retrieving all employees' ename, age, and sal, the best index choice would be a Clustered B+ tree index on fields of Emp. This type of index provides efficient retrieval of data based on the values of multiple fields. Since we need to retrieve information from multiple fields (ename, age, and sal), a clustered B+ tree index would allow us to locate the necessary records efficiently. It organizes the data in a sorted order, allowing for fast range scans and retrieval.
A clustered hash index on fields of Emp would not be suitable for this query because it is optimized for equality lookups, rather than range scans or retrieval of multiple fields. Unclustered hash indexes would also not be the best choice since they don't preserve the order of the data, making it difficult to efficiently retrieve the required fields.
If the database system does not consider index-only plans, the answer would remain the same. Index-only plans would be more relevant if we were concerned about minimizing the disk I/O by avoiding retrieving full records when all necessary information is available in the index entry. However, in this case, we need to retrieve the ename, age, and sal fields, so the index-only plans would not affect the choice of the index.
2. For the second query, which involves finding the dids of departments on the 10th floor with a budget of less than $15,000, the best index choices would be a Clustered B+ tree index on the floor field of Dept and a Clustered B+ tree index on the budget field of Dept.
A Clustered B+ tree index on the floor field of Dept would be beneficial to quickly locate all departments on the 10th floor. Similarly, a Clustered B+ tree index on the budget field of Dept would allow efficient retrieval of departments with a budget less than $15,000. Both indexes would support range scans and filtering based on the respective fields.
Clustered hash indexes and unclustered hash indexes would not be suitable for this query as they are optimized for equality lookups, rather than range scans or inequality conditions. Using a hash index on the floor field or budget field would not provide efficient retrieval for this type of query.
If index-only plans are not available, the answer would remain the same. Index-only plans would be more relevant if we wanted to avoid retrieving full records when all the necessary information is available in the index entry. However, in this case, we need to retrieve the dids of the departments, so the index-only plans would not affect the choice of the index.
