2. MySQL
MySQL (pronounced "My Sequel" or "My S-Q-L") is
an open-source relational database management
systeam (RDBMS) that allows you to manage,
organize, and retrieve data stored in a structured
manner. It is one of the most widely used
databases in the world and is commonly used for
building web applications, content management
systems, e-commerce platforms, and more.

7. What is RDBMS?
RDBMS stands for Relational Database Management System. It's a
type of database management system that is based on the principles of
the relational model of data. The relational model organizes data into
structured tables with rows and columns, where each table represents
a specific entity or concept, and the relationships between these tables
are defined by key columns.

9. What is a Database Table?
A database table is a fundamental component of a relational database
management system (RDBMS). It's a structured way of organizing and
storing data in rows and columns, similar to a spreadsheet. A table
represents a specific entity or concept, and each row in the table
corresponds to a single record or instance of that entity, while columns
represent different attributes or fields associated with the entity.
10. Here are the key components and concepts of a database table:
1. Rows (Tuples)
2. Columns (Attributes)
3. Fields:
4. Primary Key
5. Foreign Key
6. Data Types
7. Null Values

ContactName, Address, City, PostalCode and Country. The table has 5 records (rows).
12. What is a Relational Database?
A relational database is a type of database management system
(DBMS) that organizes and stores data in a structured manner using a
model called the "relational model." This model represents data as
tables (also known as relations), where each table consists of rows and
columns. Relational databases are designed to efficiently manage and
maintain large volumes of structured data while providing mechanisms
for querying, updating, and manipulating that data.
