Online transaction
The term describes a transaction that is processed in real time (see batch processing) - usually within a few seconds.
Transaction security
One of the main concerns with online transactions is transaction security, even with concurrent operations. This requires minimizing the response time and maximizing the number of transactions per time unit. The database management system, the appropriate hardware and the network components are crucial for the efficiency of an OLTP system.
ACID
ACID, also AKID in German, is an abbreviation in computer science that stands for atomicity, consistency, isolation, and durability in database management systems.
Completeness
A transaction is a sequence of database operations that are either executed in their entirety or not at all.
Consistency maintenance
A transaction must leave a consistent database state upon completion if the database was also consistent before that.
Isolation
The execution of concurrent transactions must not interfere with each other.
Durability
The data must be guaranteed to be permanently stored in the database after the successful completion of a transaction.
