A database is a systematic collection of data. They support electronic storage and manipulation of data. Databases make data management easy. Let us discuss a database example: An online telephone directory uses a database to store data of people, phone numbers, and other contact details. Your electricity service provider uses a database to manage billing, client-related issues, handle fault data, etc. Let us also consider Facebook. It needs to store, manipulate, and present data related to members, their friends, member activities, messages, advertisements, and a lot more.
Types of Database:-
-
Distributed database: A distributed database is a type of database that has contributions from the common database and information captured by local computers. In this type of database system, the data is not in one place and is distributed at various organizations.
2. Relational databases:
This type of database defines database relationships in the form of tables. It is also called Relational DBMS, which is the most popular DBMS type in the market. Database examples of the RDBMS system include MySQL, Oracle, and Microsoft SQL Server database.
3. Object-oriented databases:
This type of computer database supports the storage of all data types. The data is stored in the form of objects. The objects to be held in the database have attributes and methods that define what to do with the data. PostgreSQL is an example of an object-oriented relational DBMS.
4. Centralized database:
It is a centralized location, and users from different backgrounds can access this data. This type of computers databases stores application procedures that help users access the data, even from a remote location.
5. Open-source databases:
This kind of database stores information related to operations. It is mainly used in the field of marketing, employee relations, customer service, of databases.
6. Cloud databases:
A cloud database is a database that is optimized or built for such a virtualized environment. There are so many advantages of a cloud database, some of which can pay for storage capacity and bandwidth. It also offers scalability on-demand, along with high availability.
7. Data warehouses:
Data Warehouse is to facilitate a single version of truth for a company for decision-making and forecasting. A Data warehouse is an information system that contains historical and commutative data from single or multiple sources. The Data Warehouse concept simplifies the reporting and analysis process of the organization.
8. NoSQL databases:
NoSQL database is used for large sets of distributed data. There are a few big data performance problems that are effectively handled by relational databases. This type of computer database is very efficient in analyzing large-size unstructured data.
9. Graph databases:
A graph-oriented database uses graph theory to store, map, and query relationships. These kinds of computer databases are mostly used for analyzing interconnections. For example, an organization can use a graph database to mine data about customers from social media.
10. OLTP databases:
OLTP is another database type which able to perform fast query processing and maintain data integrity in multi-access environments.
11. Personal database:
A personal database is used to store data stored on personal computers that are smaller and easily manageable. The data is mostly used by the same department of the company and is accessed by a small group of people.
12. Multimodal database:
The multimodal database is a type of data processing platform that supports multiple data models that define how certain knowledge and information in a database should be organized and arranged.
13. Document/JSON database:
In a document-oriented database, the data is kept in document collections, usually using the XML, JSON, and BSON formats. One record can store as much data as you want, in any data type (or types) you prefer.
14. Hierarchical:
This type of DBMS employs the “parent-child” relationship of storing data. Its structure is like a tree, with nodes representing records and branches representing fields. The Windows registry used in Windows XP is a hierarchical database example.
15. Network DBMS:
This type of DBMS supports many-to-many relations. It usually results in complex database structures. RDM Server is an example of a database management system that implements the network model.
