"The fundamental unit of data storage in SQL Server is the page. The disk space allocated
to a data file (.mdf or .ndf) in a database is logically divided into pages numbered
contiguously from 0 to n. Disk I/O operations are performed at the page level. That is,
SQL Server reads or writes whole data pages."

Firebird definition of database page is the same.

Multiple records can be on one data page or one record can be split to several database
pages depending on record's size.
