How to fill a new orientdb database by data

Hello, i am novice to orientdb.
My question is:
Is there any link or just help to learn how to fill a new database newly created by orientdb. Thanx gor help

I would start by looking at the documentation for the ETL tool.
It has several examples of loading data.

If you want to move data from RDBMS over to OrientDB then take a look at the Teleporter tool.
