Consider the following relational schema:
Assume that keys are underlined and:
The relation Employee is sorted on the Id attribute.
In Department: Unclustered index on DeptName; clustered on Building. No other
indices.
Dozens of departments can reside in the same building.
(a) Write an SQL query that generates a table of employee names who work for department
?Sales? in building E213.
(b) Give the ?naive? translation of your SQL query into the relational algebra (as given by
the general translation of SQL to relational algebra.)
(c) Describe carefully and completely how you would actually most eciently evaluate the
above query. That is, list the precise sequence of relational operations to be performed,
the relations on which these operations are to be performed, and the methods to be used
to compute the result of each operation. (As part of the solution you will need to decide
which index to use and why.)
