Centalized database organizes all of an organization data , it is like a mainframe computer. Like in any company or firm all the data is integrated in to a single system.
Distributed and Centralized Databases Distributed data is defined as collection of logically distributed database which are connected with each other through a network. A distributed database management system is used for managing distributed database. Each side has its own database and operating system.A centralized database has all its data on one place. As it is totally different from distributed database which has data on different places. In centralized database as all the data reside on one place so problem of bottle-neck can occur, and data availability is not efficient as in distributed database. Let me define some advantages of distributed database, it will clear the difference between centralized and distributed database.Users can issue commands from any location to access data and it does not affect the working of database. Distributed database allows us to store one copy of data at different locations. Its advantage is that if a user wants to access data then the nearest site (location) will provide data so it takes less time.There are multiple sites (computers) in a distributed database so if one site fails then system will not be useless, because other sites can do their job because as I earlier said that same copy of data is installed on every location. You will not find this thing in centralized database.Any time new nodes (computers) can be added to the network without any difficulty.Users do not know about the physical storage of data and it is known as distribution transparency, as we know that ideally, a DBMS must not show the details of where each file is stored or we can say that a DBMS should be distribution transparent.
A centralized database contains all the data tables in one place which all users access. A decentralized database creates copies of the database design in different areas and any given copy contains only that data which is relevant to its particular users.
Transparency means that any form of distributed system should hide its distributed nature from its users, appearing and functioning as a normal centralized system
Database management involves designing the actual tables in a database and making sure that the database is up and running smoothly. This is performed by a database administrator (DBA). Data warehousing involves storing data in a database. The DBA designed the database, but someone else (or a program that someone else is running) is actually inserting the data into the database.

Wicca is not a centralized faith, with a centralized leader, and thus does not operate in any one location.
A database is useful because it provides a centralized system for storing, managing, and retrieving data efficiently. It helps maintain data integrity, enables data sharing among multiple users, enhances data security through access control, and supports complex queries and analysis.
