Raima Corp - used to be dbVista. Object-oriented database server. I had supported banking system on that platform. It was very good experience because the team was exceptional. Now it is Velosis Database Server.

Per question: this database manager was build using C/C++ libraries and should have very powerful API. You need normal C/C++ developer and the file that contains schema of the database to get data from it if you do not have report builder in that system (I had had thus I had never had any problems). It would be a huge problem if you do not have schema. As far as I am recalling – it is almost impossible to rebuild data without database schema even if you know what is there. However, they had and they have ODBC driver that should give you direct connection using SSIS in MS SQL 2005 to Raima. But I have never used it thus I am talking about developer. API is free base on info from: http://www.birdstep.com/database/Products/RDM-Server/SDK-Download/

I had known one of the guys that should be working in headquarter of the company but it was almost decade ago. Feel free to contact me if it is helpful and you think I can provide any help.
