For the bitcoin blockchain, the short answer is „no“
There are two common approaches to store data, one is with OP_RETURN, allowing for 40 bytes to store in a transaction, and then one can create a P2SH transaction, allowing for roughly 500 Bytes.
As you can see, the amounts of data are not too big, and each transaction has costs (fees), so it doesn‘t make sense.
I recommend to have a look at SIA or STORJ, to store large amount of data (files),or even at factum. The first two create hashes of a data set, that are stored. And Factum is to prove, that a set of documents exists. You find the details and n there webpages...

I know that a block comprises of transaction hashes but what if I want to make my business data completely available on the blockchain. What are the types of data that can be stored on the blockchain ? I did research on google but I didn't get the answer I needed which is why I have posted it here.
Can a blockchain store everything that a normal database can ?
