Is new 52 detective comic essential to new 52 batman?

I've been loving new 52 batman so far, the court of owls was amazing, and the story where I thought the joker actually knew batman's real identity was amazing as well. I just wanted to ask whether new 52 detective comics was a prequel or is in the same timeframe as the events of new 52 batman. Cause I heard that new 52 action comics was a prequel to new 52 superman so I was wondering if it was the same with Batman.
