A database is an organized collection of structured information or data that is typically stored electronically in a computer system. Database, also known as an electronic database, any collection of data or information that is specifically organized for quick search and retrieval by a computer. The information is transformed into helpful knowledge that is structured and managed to meet the user’s needs. Data security prevents unauthorized users from viewing or updating the database.
Navigation databases such as the hierarchical database (which was based on a tree-like model and only allowed a one-to-many relationship) and the network database (a more flexible model that allowed multiple relationships) were the original systems used to store and manipulate data.

One advantage of NoSQL databases is that developers can make changes to the database on the fly without impacting applications that use the database. They conform to ACID (atomicity, consistency, isolation, durability), a standard set of properties for reliable database transactions. Users can access the database over a computer network, but it is the central computer that runs and manages the database. OLTP is another type of database that can perform fast query processing and maintain data integrity in multi-access environments.
To use a cloud database, users can either create one themselves or pay for a service to store their data for them.
