Description: Transaction visibility refers to the ability of a transaction to see the changes made by another transaction. This concept is fundamental in the field of databases, especially in database management systems (DBMS) that handle multiple transactions simultaneously. Transaction visibility is closely related to transaction isolation, which is one of the isolation levels defined by the SQL standard. Depending on the configured isolation level, a transaction may or may not see the changes made by other ongoing transactions. For example, at the ‘Read Uncommitted’ isolation level, a transaction can see changes from another transaction that has not yet been committed, while at ‘Serializable’, it will not be able to see those changes until the other transaction is completed. Proper management of transaction visibility is crucial to ensure data consistency and integrity in environments where multiple users or processes interact with the database at the same time. Adequate handling of transaction visibility helps prevent issues such as dirty reads, non-repeatable reads, and phantom reads, which can compromise data quality and user experience.<\/p>\n","protected":false},"excerpt":{"rendered":"
