The 3 important benefits that databases have over different, less complicated statistics garage systems (including textual content documents and spreadsheets) are getting admission to, integrity, and security.
Access
Access is ready making statistics to be had to customers.
Databases assist suitable statistics to get admission to because:
Large volumes of statistics may be saved in a single place
Multiple customers can examine and adjust the statistics on the equal time

To make sure the integrity of a database, every extrude or transaction have to comply with a fixed of regulations referred to as an ACID:
Atomicity: while converting statistics inside a database, if any part of the extrude fails, the complete extrude will fail and the statistics will continue to be because it turned into earlier than the extrude turned into made; this prevents partial facts from being created
Consistency: earlier than statistics may be modified in a database, it has to be tested towards a fixed of regulations
Isolation: databases permit a couple of adjustments on the equal time, however, every extrude is remoted from others
Durability: as soon as an extra has been made, the statistics are safe, even withinside the occasion of machine failure
In addition, databases can have mechanisms for backup, distribution, and redundancy, to make sure statistics isn’t always lost.
Security
While getting admission to textual content documents or spreadsheets may be secured, as soon as a person has gotten admission to a file, they’ve to get admission to all statistics inside that file. Databases may be made very secure, and that consists of the capacity to have to get admission to rights to precise elements of the database and now no longer others.
