 # iotdb_mongodb_odl_server
 
 This is a [odl](https://www.mongodb.com/initiatives/data-as-a-service) based on mongodb.
-This app created with [Boost c++ libraries](https://www.boost.org/) , [mongo database](https://www.mongodb.com/) and [c++ 2014 standards](https://en.wikipedia.org/wiki/C%2B%2B14) .I'm developing this application only on linux and I don't know if it works on windows too and I don't care too.
