The document discusses different types of databases. It defines a database as a collection of organized data that can be easily updated, expanded, and deleted. It then describes three main types of databases: relational databases which organize data into tables with columns and rows, distributed databases which spread data across multiple physical locations, and cloud databases which run on cloud computing platforms. For each type it provides an example definition and discusses their advantages and disadvantages.

5. Database
- A database is a collection of data that is
organized, which is also called structured data.
- In a database, data is organized into tables
consisting of rows and columns and it is indexed
so data can be updated, expanded, and deleted
easily.

10. Relational Database
- A relational database is a collection of information
that organizes data in predefined relationships
where data is stored in one or more tables (or
"relations") of columns and rows.

13. Distributed Database
- A distributed database is basically a type of
database which consists of multiple databases that
are connected with each other and are spread
across different physical locations.

15. Advantages & Disadvantages of
Distributed Database
Advantages:
● This database can be easily expanded as data is already spread
across different physical locations.
● The distributed database can easily be accessed from different
networks.
● This database is more secure in comparison to a centralized
database.
Disadvantages:
● This database is very costly and is difficult to maintain because of its complexity.
● In this database, it is difficult to provide a uniform view to users since it is spread across
different physical locations.

17. Centralized Database
- A centralized database is basically a type of
database that is stored, located as well as
maintained at a single location only. This type of
database is modified and managed from that
location itself.

19. Advantages & Disadvantages
Advantages:
● Since all data is stored at a single location only thus it is easier to
access and coordinate data.
● The centralized database has very minimal data redundancy
since all data is stored in a single place.
● It is cheaper in comparison to all other databases available.
Disadvantages:
● The data traffic in the case of a centralized database is more.
● If any kind of system failure occurs in the centralized system then
the entire data will be destroyed.

21. Cloud Database
- A cloud database is a database that typically runs
on a cloud computing platform. Database service
provides access to the database. Database
services make the underlying software-stack
transparent to the user.

Images reveal large amounts of data, so
remember: use an image instead of a long text
