Do Moralis save data in blockchain or MongoDB type form?

As a beginner, its a basic doubt.
Does Moralis save data in MongoDB like tables or in Blockchain formate ?
Is it more safer then MongoDB ? or equal ?

the data for your Moralis server is saved in a Mongo DB database. I don’t know what you mean by a “Blockchain formate”

sir, i want to save some data in blockchain.
how to do it ?
does moralis don’t save data in blockchain?

what do you mean by saving data on blockchain?
usually you make a smart contract and call a function for that smart contract in order to do some updates on chain
