During which operations is an Access Lock most commonly used?

An Access Lock is primarily used to ensure that data can be accessed concurrently without causing conflicts or inconsistencies. This type of lock permits concurrent read and write access to the data, but it regulates how those accesses can happen to maintain data integrity. It is commonly employed during operations that require allowing multiple users to read data at the same time while also permitting writes in a way that does not prevent those reads.

In the context of high-volume read transactions, while access locks do allow reads, the emphasis is more on the operation's mechanism to ensure that exclusive access isn't inadvertently granted. The objective of an Access Lock is not about exclusivity, which is often the focus of different lock types, but rather managing multiple accesses efficiently. Therefore, the key function of the Access Lock is to maintain a balance that allows data retrieval without restricting access more than necessary, ensuring that the overall operations can be performed smoothly.
