Datenisolation

Datenisolation refers to the concept of separating data from different users, applications, or systems to ensure privacy, security, and integrity. This separation prevents unauthorized access or modification of sensitive information. In database systems, data isolation is a fundamental property of transactions, ensuring that concurrent transactions do not interfere with each other in unexpected ways. Database isolation levels, such as read uncommitted, read committed, repeatable read, and serializable, define the degree to which transactions are isolated from the effects of other concurrent transactions. Higher isolation levels provide greater protection against data anomalies but can reduce concurrency and performance. Beyond databases, data isolation is also crucial in cloud computing, where multi-tenant environments require robust mechanisms to keep customer data separate. Virtualization technologies also employ data isolation to create distinct virtual machines that operate independently. The goal of data isolation is to maintain the confidentiality, integrity, and availability of data by creating clear boundaries between different data sets.
