As a former Hungarian Notation user, I've since come to see the
shortcomings of such systems. One of the main problems is that your
abbreviations are not universal: is is 'c'haracter, 't'ext, 'v'archar,
'b'inary text, or what?
Different database systems have different datatypes, and some let you
define your own custom data types. What do you do then?
I now use a plain, descriptive column name, and rely on the DDL if a
dev needs to know the data type.
