Hi, I'm just trying to work of granularity hierarchies and i'm confused by what's being said.

Db: database
File: table
Page: row
Record: record

How is a row/page and a record (that's a tuple, yes?) different?

e.g.
Db: myDatabase
File: users
Page: ???
Record: bob, smith, 19, the road, the town

in the concept and design stage, there is no such thing as a page

only when you go off into the arcane world of database administration do pages matter
