With Yes
and No you can define fields with
Boolean data types (for non IT-experts: True/Yes = 1
and False/No =0). For example: You
want to protocol, if you had a headache or not.
The Unit
for the data type as well as Min. and
Max. values are only used with the
numeric data type. If you do not enter a value the entry will be automatically
null/zero.
You can define low level values (Min.) and high level values (Max.). This is sort of a safety function
for typing errors. If you want to protocol for example how much you are
drinking during a day a maximum value of 10 (liter) can make sense, so you can
not enter 25 (liter) instead of 2,5 (liter) accidentally.
If you
enter values in Target Min. and Target Max. there will be red lines for these
values in the statistical graphs, so you can see at a glance when your values step
over or under your target range.
In the field Remark you can make a note why you edited this data type.
