A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database. Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data.

Database types are group in to two major categories - Relational databases and NoSQL databases. The relational database is the most common type of database, especially in the enterprise space. It is built on a table-based format, where data are stored in rows and columns. This makes it easy to query for precise data. NoSQL databases are designed to handle the needs of Big Data by scaling out across multiple nodes. They do not have a fixed schema but instead allow for different schemas to be implemented with ease. This type of database is designed for specific use cases or applications rather than general usage across all industries or companies.

Databases are a structured collection of data. They can be classified according to their purpose.In the case of a relational database, it is used for storing large amounts of data that can be accessed via queries and SQL statements.
