I'm developing a database for scientific recordings. These recordings are traditionally saved as binary flat files for simplicity and compact storage. Although I think ultimately having a database is better than 1,000s of flat files in terms of data access, I've found that the database (or at least my design) is pretty wasteful on storage space compared with the binary flat files.
In particular, I tried importing all of the data from a binary flat file that is 1.35 MB into a PostgreSQL database (a very small test file; average production file is probably more like 100 MB). The database directory ballooned from 4.1 MB to 92 MB (a bloat of 65X the original storage of the binary flat file).
Now I know that table design and normalizing is important. As far as
my partner and I can tell, we've made good use of normalizing (no
redundancy), we've set field sizes to their theoretical skinniness,
