There are five high level datatypes that can be stored in tuples: integers, variable precision numbers, fixed point precision numbers, variable length values, and dates times. most dbmss store integers using their “native” c c types as specified by the ieee 754 standard. these values are fixed length. examples: integer, bigint, smallint, tinyint.

Material for carnegie mellon university's intro to database systems (fall 2019) 15 445 645. this course is on the design and implementation of database management systems. Tuple storage a tuple is essentially a sequence of bytes. it's the job of the dbms to interpret those bytes into attribute types and values. the dbms's catalogs contain the schema information about tables that the system uses figure out the tuple's layout.
