what’s storage manager in DBMS
content
- a part of a Database Management System, it deals with pages
- not to confuse with buffer pool, which moves data back and forth between memory and disk
how storage manager is used:
- the upper layer of DBMS asks for some data, which will then be converted to a page id, of which the data is stored on
- based on the page id, storage manager finds the file that contains the page, and the offset needed to reach that page
