Ethereum uses a key-value database library, LevelDB

the account(private key or contract) is a basic unit of storage

key(address value) (account object - nonce, balance, codeHash, stroageRoot)

and all data is stored encrypted

Patricia Tree document

your question is general, so if you point specific topic, I will try to find related document

    LevelDB does not support search functionality. users must access data by key
