Answer:

Make use of hash tables

Explanation:

The appropriate thing to use for this should be a hash table.

A Hash Table can be described as a data structure which stores data in an associative manner. In a hash table, data is stored in an array format, where each data value has its own unique index value. Access of data becomes very fast if we know the index of the desired data. So we can perform Hashing on ISBN Number since its unique and based on the Hash Function w ecan store the Information record.

There is no requirement for printing the file in order - HashTables dont store the data in order of insertions, so no problems with that

It becomes a data structure in which insertion and search operations are very fast irrespective of the size of the data. So Querying books details can be fast and searching will take less time.

It can also be pointed out that it wont be too expensive for Hardware implemtation as HashTables stores data based on Hash Functions and memory consumption is also optimal which reduces memory wastages.

Why are smartphones and tablets capable of handling rich content and interactivity?

NikAS [45]

Answer:

Explanation:

With the advance in technology, smartphones, and tablets are built to meet the ever-increasing needs of users.

Smartphones are mobile phones that also have internet connectivity, they can be used to make calls and perform many tasks just like the conventional desktop. Smartphones and tablets are indeed considered computers because they also process inputs in form of commands and they produce outputs.

Smartphones and tablets are capable of handling rich content and interactivity because:

1. Wireless synchronization with other devices: Just like desktops, laptops, they can interact with other devices, and can receive and also send information doesn't matter the distance.

2. They have Internet connectivity.

3. They have strong hardware, good storage capacity.

4. They have inbuilt software and are capable of accepting other software and programs.

5. They are built with an appealing user interface.

6. Just as computers have processors, smartphones and tablets also have processors to ensure their speed at processing informations.

Consider the following relation:CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)Assume that a car may be sold

GalinKa [24]

Answer:

The answer to this question can be given as:

Normalization:

Normalization usually includes the division of a table into two or more tables as well as defining a relation between the table. It is also used to check the quality of the database design. In the normalization, we use three-level that are 1NF, 2NF, 3NF.

First Normal Form (1NF):

In the 1NF each table contains unique data. for example employee id.

Second Normal Form (2NF):

In the 2NF form, every field in a table that is not a determiner of another field's contents must itself be a component of the table's other fields.

Third Normal Form (3NF):

In the 3NF form, no duplication of information is allowed.

Explanation:

The explanation of the question can be given as:

Since all attribute values are single atomic, the given relation CAR_SALE is in 1NF.
Salesperson# → commission% …Given Thus, it is not completely dependent on the primary key {Car#, Salesperson#}. Hence, it is not in 2 NF.

The 2 NF decomposition:

CAR_SALE_1(Car#, Salesperson#, Date_sold, Discount_amt)

CAR_SALE_2(Salesperson#, Commission%)

The relationship in question is not in 3NF because the nature of a transitive dependence occurs
Discount_amt → Date_sold → (Car#, Salesperson#) . Thus, Date_sold is neither the key itself nor the Discount amt sub-set is a prime attribute.

The 3 NF decomposition :

CAR_SALES_1A(Car#, Salesperson#, Date_sold)

CAR_SALES_1B(Date_sold, Discount_amt)

CAR_SALE_3(Salesperson#, Commission%)
