The different types of databases include operational databases, end-user databases, distributed databases, analytical databases, relational databases, hierarchical databases and database models. Databases are classified according to their type of content, application area and technical aspect. For instance, a deductive database combines logic programming with a relational database, while a graph database uses graph structures to represent and store information.Know More
Other types of databases include hypertext databases, mobile databases, parallel databases, active databases, cloud databases, in-memory databases, spatial databases, temporal databases, real-time databases, probabilistic databases and embedded databases.
A database is an organized collection of data. Its primary function is to interact with a database management system to capture and analyze data. A database management system is a software system designed to allow the creation, querying and administration of databases. Some popular database management systems include PostgreSQL, MySQL, Microsoft SQL Server, Oracle, IBM DB2 and SAP.
Databases are designed to operate large amounts of information by inputting, storing, retrieving and managing it. They are set up in a way that allows users to easily and intuitively gain access to all the information. A database management maintains the integrity and security of stored data. It is also used for data recovery, in case of system failure.Learn more about Software
