ACID

(Atomic, Consistent, Isolated, Durable) The properties of a transaction in a well-designed database management system (DBMS). The transaction must be ATOMIC (all updating tasks must be completed or nothing is done), CONSISTENT (it cannot leave the database in a state that violates any integrity rules), ISOLATED (remain invisible to other operations until completed) and DURABLE (will complete or be reversed if the system fails in the interim).

Most of above researches concentrate on protocols of e-commerce and model checking of such transaction properties as atomicity, but the validations of protocols are not sufficient to ensure the integrity and reliability of e-commerce systems because there are still many defects and logic errors at the design level of business processes, which can be exploited by malicious clients.

The OI that compose each schema are not raised in isolation but that can exist different relationships between OI belonging to different schemas, in addition, an OI specification level is determined according to the atomicity of the entity to which it is related, from one level of abstraction defined.
where, DD is deacetylation degree of chitosan; R is the mass ratio of carbon and nitrogen; [n.sub.c] is the atomicity of carbon on substituted unit; [M.sub.C] and [M.sub.N] are the relative atomic mass of carbon and nitrogen, respectively [20].
Atomicity, speed and easy implementation are the main features of reductive registration.
Other features of the operating system include improved atomicity, adaptable filesystem-level encryption and TRIM support.
In addition, it also has had ACID transactions (ACID stands for Atomicity, Consistency, Isolation, and Durability).
Another weakness is that they do not support ACID (Atomicity, Consistency, Isolation and Durability) as provided by relational database.
