A database is a structured and organized collection of data that is stored and managed to enable efficient retrieval, updating, and analysis. It serves as a digital repository, systematically organizing information in a way that facilitates data manipulation, storage, and retrieval. Databases play a crucial role in various fields, ranging from business and science to education and government.

3. Introduction to Database
Definition:
• Well-organized collection of Data that
is stored in a computer system.
Importance:
• Provides a centralized location for storing data
• Easy to manage and access

4. Purposes of
Database
To provide an
organizational
structure for
data
To store Data
Data isolation-
multiple files
and formats
Data
redundancy
and
inconsistency
To provide a
mechanism
for querying,
creating,
modifying,
and deleting
data
Reduce
difficulty in
accessing of
data
Durability-
Written data
will not be lost

NoSQL / Non-relational database
NoSQL databases (aka "not only SQL") are
non-tabular databases and store data
differently than relational tables. NoSQL
databases come in a variety of types based
on their data model. The main types are
document, key-value, wide-column, and
graph.

8. Structured query language
(SQL) is a programming
language for storing and
processing information in a
relational database.

10. Database Management system
A database management
system (DBMS) is system
software for creating and
managing databases. A
DBMS makes it possible for
end users to create, protect,
read, update, and delete
data in a database.

12. Database security
Security of databases refers
to the array of controls,
tools, and procedures
designed to ensure and
safeguard confidentiality,
integrity, and accessibility.

Data backup and Recovery
Recovery from a backup
typically involves restoring
the data to the original
location, or to an alternate
location where it can be
used in place of the lost or
damaged data.

14. Big Data and Databases.
Big data databases store massive
quantities of structured, semi-
structured, and unstructured data,
without strict schemas. The fast
and scalable NoSQL database can
collect data from various sources,
including social data, machine data
(IoT) and transactional data
(applications).

15. Cloud Databases
A cloud database is a database built to
run in a public or hybrid cloud
environment to help organize, store, and
manage data within an organization.
Cloud databases can be offered as a
managed database-as-a-service
(DBaaS) or deployed on a cloud-based
virtual machine (VM) and self-managed
by an in-house IT team.
