In database systems, isolation is one of the ACID ( Atomicity, Consistency, Isolation, Durability) transaction properties. It determines how transaction integrity is visible to other users and systems. A lower isolation level increases the ability of many users to access the same data at the same time, but also increases the number of ...
Isolation Forest is an algorithm for data anomaly detection initially developed by Fei Tony Liu in 2008. [1] Isolation Forest detects anomalies using binary trees. The algorithm has a linear time complexity and a low memory requirement, which works well with high-volume data. [2] [3] In essence, the algorithm relies upon the characteristics of ...
ACID. In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. [1] In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a ...
Atomicity (database systems) In database systems, atomicity ( / ˌætəˈmɪsəti /; from Ancient Greek: ἄτομος, romanized : átomos, lit. 'undividable') is one of the ACID ( Atomicity, Consistency, Isolation, Durability) transaction properties. An atomic transaction is an indivisible and irreducible series of database operations such ...
Snapshot isolation. In databases, and transaction processing (transaction management), snapshot isolation is a guarantee that all reads made in a transaction will see a consistent snapshot of the database (in practice it reads the last committed values that existed at the time it started), and the transaction itself will successfully commit ...
Process isolation is a set of different hardware and software technologies [1] designed to protect each process from other processes on the operating system. It does so by preventing process A from writing to process B. Process isolation can be implemented with virtual address space, where process A's address space is different from process B's ...
Isolation is the property that provides guarantees in the concurrent accesses to data. Isolation is implemented by means of a concurrency control protocol. The simplest way is to make all readers wait until the writer is done, which is known as a read-write lock .
Information silo. An information silo, or a group of such silos, is an insular management system in which one information system or subsystem is incapable of reciprocal operation with others that are, or should be, related. Thus information is not adequately shared but rather remains sequestered within each system or subsystem, figuratively ...
