Databases

CRUD:

• Create
• Retrieve
• Update
• Delete

Also, it has:

• Integrity - Even if the data changes the applications using the data do not need to be changed
• Backups - easily backs up the data which means that the database is unlikely to be lost
• Consistency - the data is the same regardless of who is viewing it
• Security - Can control who can access which data
• By using unique identifiers data redundancy can be avoided, which reduces the file size

• Allows different views of the database 
• The external view of the DB is done by people who input or view the data
• A conceptual view is useful for the DB designer
• An internal view is used for the detailed programming of the DB
