I am an ocasional Python programer who only have worked so far with MYSQL or SQLITE databases. I am the computer person for everything in a small compamy and I have been started a new project where I think it is about time to try new databases.

Sales departament makes a CSV dump every week and I need to make a small scripting application that allow people form other departaments mixing the information, mostly linking the records. I have all this solved, my problem is the speed, I am using just plain text files for all this and unsurprisingly it is very slow.

I thought about using mysql, but then I need installing mysql in every desktop, sqlite is easier, but it is very slow. I do not need a full relational database, just some way of play with big amounts of data in a decent time.

Many thanks!
