WAL is an acronym that can stand for different things depending on the context. One of the most common definitions of WAL is "Write-Ahead Logging" in the field of computer science and database management systems.
In this context, WAL refers to a technique used for ensuring data consistency and durability. It involves the process of writing data modifications to a log file before applying them to the database itself. This logging mechanism ensures that data is always recoverable in the event of a system failure. By writing logs before making the actual changes, it allows for rollback or redo operations if needed.
The WAL technique is commonly used in database systems to improve performance and prevent data loss. It provides an additional layer of protection by allowing transactions to be recovered and applied after a system crash or power failure, ensuring that data integrity is maintained.
Apart from its computer science definition, WAL can also stand for "West African Airlines," referring to a former airline company operating in West Africa.
In summary, WAL primarily stands for "Write-Ahead Logging" in the field of computer science and database management systems, where it refers to a technique for ensuring data consistency and durability.
