Assume the relation CITIZEN(ID, Tax-Code, Salary, Age) storing information about UK citizens’ tax codes and annual salaries. There are r = 60,000,000 records. Each attribute has the same size: 128 bytes. The relation is stored in a file sorted by the salary attribute. The block size B = 1024 bytes and any pointer in the system has size = 128 bytes. The salary attribute is assumed to be uniformly distributed across tuples. There are 6,000 distinct salary values and there are 10,000 different tax-code values. The tax-code and age are assumed to be statistically independent of salary. A data scientist, who has built a Secondary Index over the Tax Code (non- ordering, non-key attribute), is interested in the specific Tax Code: ‘1234L’. The data scientist did analyse the distribution of the Tax Code attribute and noted the following: • Let X be the number of citizens with Tax Code 1234L per data block. That is, given a random block, there are X citizens with Tax Code 1234L. Objective:…

Consider a file with a secondary dense index structure on a non-ordering key field where 120,000 records stored on a disk with block size of 2048 bytes. Length of every record is of fixed and un-spanned Record size is 150 bytes.
Imagine a database of students where the StudentID is the main key, and there are other indexes on Major, Age, MaritalStatus, and HomeZipCode (all secondary keys). Let's assume the institution wanted a list of MIS or computer science majors who were over 25 and married and were from the 45462 postcode code OR computer engineering majors who were single and were from the 45462 zip code. In any case, they wanted the list to come from the 45462 zip code. How can indexes be used to guarantee that individuals will only have access to the info that fulfills this prerequisite?
Which of the followings can possibly be a canonical cover Fc of a set F of functional dependencies? (The actual set F or the actual relation R is not required to answer this question.)

Consider a file of 16384 records. Each record is 32 bytes long and its key field is of size 6 bytes. The file is ordered on a non-key field, and the file organization is unspanned. The file is stored in a file system with block size 1024 bytes, and the size of a block pointer is 10 bytes. If the secondary index is built on the key field of the file, and a multilevel index scheme is used to store the secondary index, the number of first-level and second-level blocks in the multilevel index are respectively
