used to develop relational databases in paradox with PAL. It allows for very nice interface. What would be the best database from open source in linux? I don't develop in SAP or Oracle because my niche is small companies that need full relational database with small budgets. I don' t uses access because after being used to paradox it is like being trown back 20 years. MySQL I use only for websites. In short: when I build a nice relational database with a nice interface: what has a real future?
