How can blockchain be used as a database to store data?
https://www.quora.com/How-can-blockchain-be-used-as-a-database-to-store-data
Currently decentralized blockchain applications have few options to store data. Decentralized storage options are:
- Storing everything in blockchain itself
- Peer to peer file system, such as IPFS
- Decentralized cloud file storages, such as Storj, Sia, Ethereum Swarm, etc.
- Distributed Databases, such as Apache Cassandra, Rethink DB, etc.
- BigChainDB
- Ties DB
- Ties DB: The currently available options could be a good public database. The closest to the ideal are the noSql databases. The only thing they lack is byzantine fault tolerance. The Ties.Network Database: ties.network is a deep modification of the Cassandra database and offers a preferable solution: The TiesDB inherits the majority of features from the underlying noSQL databases and adds byzantine fault tolerance and incentives. With these features it can become a public database and enable feature-rich applications on Ethereum and other blockchains with smart contracts. The database is writable by any user. But the users are identified by their public key and all the requests are signed. Once created, record remembers its creator who becomes an owner of the record. After that the record can be modified only by the owner. Everyone can read all records, because the database is public. All the permissions are checked on request and replication. Additional permissions can be managed via a smart contract.
Ties.DB is the answer to DApp storage
https://tiesdb.com/
A public, distributed and decentralized database with one common thread: trust. Enforced by integrated fault tolerance, incentive schemes and smart contracts.
Key features of Ties.DB
All Ethereum-based decentralized applications (DApps) need to store non-financial data and search through their documents. Ties.DB is the first public database for decentralized structured data storage and allows advanced search and documents modification.

comparison of MongoDB and Cassandra
Cassandra and Mongodb. In fact
Mongo has built in support for full text search as well. However, keeping in mind the time series nature of the data, it seems a key-value store (Cassandra) should be a better fit than a document oriented (Mongo). Also, keeping in mind the high write operation nature, it felt to me Cassandra is a better candidate. The last inference is simply based on a previous project that I had worked on, where we were prototyping a big data ingestion platform on Cassandra. So.. Cassandra!
