Example:
In a report, the Table of Contents shows the chapter names with their page numbers.
It updates automatically when you add or remove headings.

Other options:
(A) Table of Heading:
There is no such feature in OpenOffice Writer called “Table of Heading.”
This is a distractor option.
In Writer, headings are part of the document structure, but they are organized into a “Table of Contents,” not a separate “Table of Heading.”

(B) Index:
An Index is a list of specific terms or keywords with their page numbers.
It is used for referencing specific topics in the document.
Example:
In a book, an index lists terms alphabetically at the end with page numbers.
Difference:
Table of Contents → Lists headings and subheadings.
Index → Lists keywords or topics with page references.

(C) Label of Contents:
There is no such feature called “Label of Contents” in Writer.
This is a made-up option to confuse users.
The correct term is “Table of Contents.”

Ans.: (C) Blank document

Explanation:

2. Install Fire Extinguishers and Alarms: Place fire extinguishers and smoke alarms in easily accessible locations and ensure they are maintained regularly.

(b)
1. Evacuation Plan: Employees should be familiar with evacuation routes and assembly points during emergencies.

2. First Aid Assistance: Ensure there is a designated first-aid team or personnel trained to handle minor injuries.

Ans.:
(a)
1. Eliminates Data Redundancy: By relating tables, repetitive data is reduced, making the database more efficient.
2. Ensures Data Consistency: Changes made in one table are automatically reflected in the related table, maintaining consistency.

(b)
A many-to-many relationship occurs when multiple records in one table are related to multiple records in another table.

For example, in a library database, multiple students can borrow multiple books.
To represent this relationship, a junction table (also called a bridge table) is used, containing foreign keys from both tables.
This avoids duplication and ensures data integrity.

Ans.
(a)
– student_id: The appropriate datatype for the student_id field is VARCHAR or TEXT
– age: The appropriate datatype for the age field is INTEGER.

(b)
The best field to choose as the primary key is the Student_ID.
In this table, the Student_ID field contains unique values for each student (S001, S002, S003), making it the best candidate for the primary key.
Other fields, such as Name or Phone_Number, are not guaranteed to be unique

(c) The field that can serve as an alternate key is the Phone_Number

An alternate key is a candidate key that can uniquely identify each record but is not used as the primary key.
In this table, the Phone_Number field contains unique values for each student, making it suitable as an alternate key.
However, in real-world scenarios, there might be a chance of students sharing phone numbers, but in this table, the numbers are unique.

(d) Attributes – 4, records – 3
