user78208: I started local bitcoind client. And started it as RPC server. I know that i able to get balance only for my account address. But how i can work with all existing addresses? How i can get balances and txs? Maybe exist some db for this? 

user63569: You can import any address you want to watch or "work with" by navigating to console window and sending the following command:
bitcoin-cli importaddress "address" "account" <rescan>

after blockchain scanning complete you can send 
bitcoin-cli listtransactions "account" "Count" "skip" watch-only
bitcoin-cli listtransactions "*" 1 0 true

So you get all transactions.
You can get all commands from bitcoin.org
