database for scientific calculation

Question

I need to include a database in a C# project with a lot of data. This database should be free even in a commercial use.

What database should I use?

[EDIT]

I would like to know what database are to be avoided. When I say "a lot", it's for scientific calculation so it will be huge data.

Answer 1

http://www.fakenamegenerator.com/ might help you out. Depends on the type of data you need.

Answer 2

Well, you can use actually almost anything, PostgreSQL, SQLite, and even Microsoft's SQL Server Compact or SQL Server.

It also depends on what is "a lot of data"/

Answer 3

I've used PostgreSQL database for my own "semi-scientific" proof of concept project. Stored 50GB+ data. My experience is positive. You should be careful about partition scheme and indexing. It is free and supported by large online group.
