Relational flat-file database

Question

For a small application, need to use a flat file database with relational capabilities (2 or 3 tables).

Couple questions regarding this schema:

1. Does such databases exist?
2. Any performance hits with large datasets? (say, 10k-20k entries)

The reason I want to go with a flat-file database is so the whole thing(root directory) can be copied and pasted, and not have to worry about exporting the database, installing & configuring a database in another system, etc.

thanks.

Answer 1

Try SQLite.

It is easy to use, portable, no configuration and has great performance (10k / 20k is nothing)
