most of the articles cited Blockchain as a distributed database. Does it mean we can store any type of data in blockchain like audio, video ,pdf?

The blockchain-based database is a combination of traditional database and distributed database where data is transacted and recorded via Database Interface (also known as Compute Interface) supported by multiple-layers of blockchains.
Database uses centralized storage of data. Blockchain uses decentralized storage of data. Database needs a Database admin or Database administrator to manage the stored data. There is no administrator in Blockchain.
It is decentralized, distributed technology that collects a digital record of any event and store it in a distributed database that is shared among all the users connected with it. Every transaction in a blockchain is verified by the majority of the connected nodes of the system.
A blockchain can be either centralized or decentralized. It is important, however, that decentralized not be confused with distributed. While a blockchain is inherently distributed (meaning that many parties hold copies of the ledger), it is not inherently decentralized.
Think of blockchain as a relatively slow, very expensive database that provides excellent resistance to hacking and corruption. It's a Write-Once, Read Mostly (WORM) system.
You absolutely could store any data you want in a hypothetical blockchain. The practical limits are, you don't want to store very large chunks of data (so, not video); you probably don't want to store frequently changing data (so, not a thesis paper you're revising) -- unless it's important somehow to record every single change forever.
Because, its other feature is, once something is written to a blockchain, it's there forever.
Need to fix a typo? Then you add a new record with a correction.
Need to delete a record? Too bad, you can't. Best you can do is enter a new record saying that the record you wish to delete is "obsolete" or "repudiated" or "no longer valid" or "should be considered as deleted."
In short, it's wise to treat your blockchain as a permanent record.
1 Slow: the Bitcoin blockchain runs about 3 transactions per second (tps) and the Ethereum blockchain runs about 30 tps.
2 Expensive: the Bitcoin blockchain cost an average of US$ 8.22 per transaction in November 2017 according to Digiconomist.
