What is database?
A database is a collection of data that is stored and organized in a specific way, so that it can be easily accessed, managed, and updated. Databases are used in a wide range of applications and systems, such as financial systems, customer relationship management systems, and online retailers.
There are several types of databases, including:
- Relational databases: These databases use a structured approach to organize data into tables, with rows and columns, and use a specific language called SQL(Structured Query Language) to interact with the data. Examples of relational databases include MySQL, Oracle, and Microsoft SQL Server.
- NoSQL databases: These databases use a non-relational approach to store and organize data, and can be based on different data models such as document, key-value, graph, and columnar, and use specific query languages to interact with the data. Examples of NoSQL databases include MongoDB, Cassandra and Redis.
- Object-oriented databases: These databases use object-oriented programming concepts to store and manage data, and are often used in applications that require the storage and manipulation of complex data structures.
Overall, databases are important for storing, managing, and retrieving data in a fast and efficient manner, which is crucial for the functioning of many modern systems and applications.
