TinyDB question

I wanna use TinyDB to storage date.

Is there a way for Tinydb to read only the last piece of data?

What is last piece?

Under a tag, if you write data into it thrice,
say first time "A"
then "B"
then "C".
If you now use the getValue block for the particular tag, only C will be returned.

Tiny db would return the latest value for the respected tag

So if C is the last value then it has to return C

maybe this can help :

Thank you for your help, I just had time to read it now

I will review one by one and then test
