Explain how the “Database Writer” process works?

[mayur-srivastava-969b4813 (Mayur Srivastava)]

It’s feasible to run several database context processes. They’re known as “DBWn” in the operating system. This technique is responsible for storing “dirty” buffers on the hard drive. When a server process has to update a data block, it reads it from the disc into the buffer cache if it isn’t already there, then updates the cache copy. As a result, a “dirty” block in the buffer cache corresponds to a changed database block.
