Assuming that a query has a buffer holding up to 3 blocks, and each block can hold two records. Use merge-sort to sort the following records in ascending order: 10, 11, 1, 5, 90, 1, 2, 101 (a) How many runs will be produced in the whole algorithm and what are the contents of the runs? (b) Clearly identify what the algorithm will do in each merge pass. (c) Over the entire course, how many blocks are transferred from the disk to the memory?

Why it's useful to have index that partially sort a query if it doesn't present all of the results already sorted?
In Oracle database, if we have any field such as Job_Title field in any of our table then we can use DECODE function to sort the result based on our own numerical value. This can be done by including the following in ORDER BY clause: 1: ORDER BY DECODE(job-title,'Manager',3,Assistant',2,'Sales Rep', 1) DESC II: ORDER BY DECODE(job-title,'Manager', 3,'Assistant',2, Sales Rep', 1) ASC III I and II are correct IV I and II are incorrect ||| IV || 1
How is a clustered index made, and what are the main differences between a clustered index and a sparse index?
When working with a relational database, a select operation may be used to reduce the amount of space used by a table by removing columns that meet certain requirements.Is this the right answer or the wrong answer?

Give a query that would benefit from each of the three methods of partitioning: round-robin (the most common), hash partitioning (the second most common), and range partitioning (the third most common).
1) Does proper indexing make it possible for some join queries to not need to retrieve a table entry at all to be used effectively in choosing results? True False 2) Which operation is a Hash based Index optimal for? A) Range matching (ie x >= 10) B) Pattern matching (ie x LIKE "Th%") C) Equality matching (ie x = "This") 3) A Composite Search Key (ie WHERE age > 10 AND name = "Yossarian") can make use of which indexes with partially matching attribute lists? (select all that apply) A) Hash index of single key (ie age) B) Hash index of multiple keys (ie age, name, gender) C) B+ Tree index of a single key (ie age) D) B+ Tree index of multiple keys (ie age, name, gender)
Selected columns are removed from a table using a relational database's "select" method.It's possible that I'm mistaken.
Explain the method of partitioning secondary index by term.
Select operations in relational databases are used to reduce the number of columns in a table based on predefined conditions.Where do you stand on this?
Refer to the film and inventory tables of the Sakila database. The tables in this lab have the same columns and data types but fewer rows. Write a query that lists the titles of films with the fewest rows in the inventory table. This query requires a subquery that computes the minimum of counts by film_id: SELECT MIN(count_film_id) FROM ( SELECT COUNT(film_id) AS count_film_id FROM inventory GROUP BY film_id ) AS temp_table; This subquery is provided in the template.
