Isolation (computer science) - Wikipedia, the free encyclopedia (1312 words) |
 | In database systems, isolation is a property that the changes made by an operation are not visible to other simultaneous operations on the system until its completion. |
| This is because to maintain the highest level of isolation a DBMS must acquire locks on data, which may result in a loss of concurrency, or else implement multiversion concurrency control, which may require additional application logic to function correctly. |
| Conversely, at higher isolation levels the possibility of deadlock is increased, which also requires careful analysis and programming techniques to avoid. |
