Would it make sense to build a similar type of a database for Haskell? What do you think?
I used mnesia in a little Erlang project I did. It did nearly everything I wanted it to (and stuff I didn't need since it does replication and my project didn't require it.) The one item I didn't care too much about is that your data integrity is enforced by your application. There didn't appear to be constructs that let mnesia protect data corruption. Admittedly, I am inexperienced with mnesia. There may be a way to add constraints and I just missed finding it in the documentation. I prefer using HSQL with PostgreSQL. PostgreSQL meets ACID requirements. It supports foreign key constraints, index constraints, and column constraints. It has stored procedures and triggers. And on and on. When HSQL says a transaction has been committed, I *know* the data is safe. -- Rich AIM : rnezzy ICQ : 174908475
