Suggestion for EDS:
1. if user stores a sequence, make EDS can check if it is
a string (all bytes 0-255). If yes, store as string (just use 1
byte per atom). If not, store as usual. If this is make EDS slower
make function enable_string() and disable_string() for example.
So I can store contents of a 1 MB file without having a 4 MB .edb
file.
2. can make autonumber especially for record keys. and add indexing
in same file (.edb) for record data.
3. add encryption with password.
Thanks!

EDS only uses one byte per character for strings
(except for extremely rare cases where 2 bytes might be used).
There's also a couple of bytes of overhead.
See compress()/decompress() in database.e

I'll think about it.

The data is already slightly encrypted,
i.e. you can't load a .edb file into an editor
and visually read the strings or the numbers.
I'm not sure I want to implement one of the
strong encryption algorithms. There are still some
U.S. export restrictions on encryption algorithms.
I wouldn't want Euphoria to be banned from
distribution by the large U.S. shareware sites.

EDS is a free database designed by RDS for EUPHORIA.
It's a very easy database to learn and there are a couple
of eamples on the user contrib page.
I recommend d/l ing EDS and reading the HTM that
is supplied with the database.

Suggestion for EDS (eu database system):
Table can have more than 1 same key.
User will define if it can have > 1 same key on
db_create_table, such as
db_create_table({"data", DB_MULTI_KEY})
-- to be compatible with older version
Thanks!
