Lowest-cost way to compute r and s relations: The relation “r” is called the outer relation and “s” is called the inner relation of the join, since the loop for “r” encloses the loop for “s”. The user can store the whole smaller relation in memory, read the larger relation block by block and perform nested loop join using the larger one as the outer relation. The nested loop join algorithm is expensive, since it examines every pair of tuples in the two relations...

Explanation of Solution

Lowest-cost way to compute r and s relations:

The relation “r” is called the outer relation and “s” is called the inner relation of the join, since the loop for “r” encloses the loop for “s”.

The user can store the whole smaller relation in memory, read the larger relation block by block and perform nested loop join using the larger one as the outer relation.

The nested loop join algorithm is expensive, since it examines every pair of tuples in the two relations...

Explanation of Solution

Amount of memory required for this algorithm:

The number of I/ O (Input/ Output) operations is equal to “b_r + b_s”, and memory requirement is “min (b_r + b_s) + 2” pages...

1. Create a Person.java file. Implement the public Person and Student classes in Person.java, including all the variables and methods in the UMLS. Person -name: String -street: String -city: String +Person(String name, String, street, String, city) +getName(): String +setName(String name): void +getStreet(): String +setStreet(String street): void +getCity(): String +setCity(String City): void +toString(): String Student -Id: int +Person(String name, String, street, String, city, int Id) +getId(): int +setId(int Id): void +toString(): String 2. Create a StudentTest.java file. Implement a public StudentTest class with a main method. In the main method, create one student object and print the object using System.out.println(). Your printing result must follow the example output: name: Mike, street: Morris Ave, city: Union, Id: 1000 Hint: You need to modify the toString methods in the Student class and Person class!
