Develop database recording rise of this larva (7)

I believe the answer is:

tadpole

I'm a little stuck... Click here to teach me more about this clue!

'this larva' is the definition.
(tadpole is a kind of larva)

'develop database recording rise' is the wordplay.
'TADPOLE' is hidden back-to-front within the letters.
But, I'm not sure how this is indicated.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for tadpole that I've seen before include "Embryonic frog" , "Frog in formation" , "Young amphibian" , "Larval form" , "Pre-frog form" .)

I've seen this clue in The Irish Times.
