There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Should or can the data be controlled by a central authority?
There remain many reasons why a third party should be in charge of some authentications and authorizations.

There are times when third-party control is totally appropriate and desirable.

If privacy of the data is the most important consideration, there are ways to secure data by not even connecting it to a network.

Private key cryptography enables push transactions, which don’t require centralized systems and the elaborate accounts used to establish digital relationships.

If this database requires millions of dollars to secure lightweight financial transactions, then there’s a chance blockchains are the solution.

Is the speed of the transaction the most important consideration? Does this database require high-performance millisecond transactions?

If high performance, millisecond transactions are what is required, then it’s best to stick with a traditional-model centralized system.

Blockchains as databases are slow and there is a cost to storing the data – the processing (or ‘mining’) of every block in a chain.

Centralized data systems based on the client-server model are faster and less expensive… for now.
