Review on IRONdb by Rick Rogers

It's super intuitive. I can create my own queries in less than 5 minutes which gives me great flexibility when implementing it within our system. There are no hard limits or quotas so i have total control over usage across all servers. The UI could be improved but this comes down to personal preference as there isn't anything that annoys me about it. For any new developer looking for an ETL solution with flexible query capabilities consider IronDB. They support our entire workflow from importing source files directly into a SQL server via API calls and a very powerful ETL process using IronDB.
