Consider the “index calculation” problem we have studied in the class (see lecture note), where we have a relation of 8,000,000 tuples. Again, make the following assumptions:

• the size of disk block (also called disk page): it is usually 4K or 8K bytes, to make our calculation easier, we will use 4000 bytes as a block size
• the size of the search key value: say we index the relation by using an attribute that is part of the primary key, and it is 40 byte string
• the size of physical page addresses: this is needed since every node in the tree will store search key values as well as references to disk pages, i.e., the address of the disk page being referenced. For ease of calculation, we use a 10-byte page address
• each swap takes about 10 milliseconds

1. For this relation, calculate how long it will take to find a particular record if we use dense index, as

described by databaseSystems-71-indexing, page 2? [16 points]

2. Consider again the situation in question 1, with the same dense index, but add one extra level of sparse index, as described by databaseSystems-71-indexing, page 5 – 6. Now, how long it will take to find one particular record? [16 points]

Westpac City-Bay Fun Run is an annual fund-raising event that started in Adelaide in November of 1973. The main purpose of the event is to raise funds to support the athletic community of South Australia and to support local athletes and clubs while also engaging in a fun and friendly competition.

“The start of many mental health conditions most often occurs in adolescence. Half of individuals living with mental illness experience onset by the age of 14.
