MySQL is an open-source relational database management system (RDBMS) that supports structured query language (SQL) and operates on various platforms like Windows, Linux, and macOS. It organizes data into tables with relationships defined by primary and foreign keys, facilitating efficient data management and retrieval. MySQL is suitable for both small and large applications, offering features such as high availability, security, and the ability to handle large data volumes.

4.  MySQL is an open source relational database.
 MySQL is cross platform which means it runs on a
number of different platforms such as Windows,
Linux, and Mac OS etc.
 Supports standard SQL (Structured Query
Language).

5.  Relational Database Management Systems (RDBMS) a
software is used to store, manage, query and retrieve
huge volume of data from a relational database.
 An interface between users, applications and database.
 This is called relational database because all the data is
stored into different tables and relations are established
using primary keys or other keys known as Foreign
Keys.

6. • Database − A database is a collection of tables, with
related data.
• Table − A table is a matrix with data. A table in a
database looks like a simple spreadsheet.
• Column − One column (attribute/data element) contains
data of one and the same kind, for example the column
postcode.
• Row − A row (= tuple, entry or record) is a group of
related data, for example the data of one subscription.
• Redundancy − Storing data twice.
RDBMS Terminology

7. • Primary Key − A primary key is unique. A key value
can not occur twice in one table. With a key, you can
only find one row.
• Foreign Key −Foreign keys are the column of the table
used to point to the primary key of another table.
• Compound Key − A compound key (composite key) is
a key that consists of multiple columns, because one
column is not sufficiently unique.
• Index − An index in a database resembles an index at
the back of a book. Indexes are used to find rows with
specific column values quickly.
• Referential Integrity − Referential Integrity makes sure
that a foreign key value always points to an existing
row.

8.  SQL is a standard database language used to
access and manipulate data in databases. SQL
stands for Structured Query Language. SQL was
developed by IBM Computer Scientists in the
1970s.
 By executing queries SQL can create, update,
delete, and retrieve data in databases like MySQL
. Overall SQL is a query language that
communicates with databases.
