ACID properties are the backbone of database
A: Atomicity
C: consistency
I : Isolation
D: durability
Atomicity : Atomicity is a feature of databases systems dictating where a transaction must be all-or-nothing. That is, the transaction must either fully happen, or not happen at all. It must not complete partially
Consistency: Consistency, in the context of databases, states that data cannot be written that would violate the database’s own rules for valid data. If a certain transaction occurs that attempts to introduce inconsistent data, the entire transaction is rolled back and an error returned to the user.
Isolation : Transaction isolation is an important part of any transactional system. It deals with consistency and completeness of data retrieved by queries unaffecting a user data by other user actions. A database acquires locks on data to maintain a high level of isolation.
Durability: Durability in databases is the property that ensures transactions are saved permanently and do not accidentally disappear or get erased, even during a database crash. This is usually achieved by saving all transactions to a non-volatile storage medium.
the main advantage is data is organized in tables form and is redundant
