i want create a healthcare system using hyperledger Composer for fast processing. I don't want to store the healthcare records on the blockchain as it takes a lot of space.  Instead, I want to store the hash of the record on the blockchain and storing the actual records on the database.

What could be the best choice of databae for this purpose??

To read and add data you can just use Composer's Rest Server functionality. The exposed RESTfulm endpoint can be called from the datalayer of your application.

For the database, you can use SQL , however the choice of database depends on the kind of development environment you are using. If your data is not that big you can consider AWS RDS cloud databases.

You can store the location if your data on the blockchain. By defining an asset in the Composer CTO and giving it a String property with a location. You can use the playground codes examples for reading and writing autogenerated Asset Registry. Use RESTful endpoint to read and write the data.
