There are a number of databases in sage, for curves or graphs or what have you. Where can I find the schemas for these?

The elliptic curves database is not a SQL database, so it doesn't have a "schema" as such -- it's just a bunch of Python objects.
for any database that is a sqlite3 database, you could just use sqlite3 (the command line tool) to output the schema for the database (by doing sage -sh then sqlite3 databasefile). You'll have to find the database file in the SAGE_ROOT/data/ directory.
```
sage -sh
cd $SAGE_ROOT/data/graphs/
sqlite3 graphs.db
sqlite> select * from sqlite_master;
table|degrees|degrees|2|CREATE TABLE degrees(
...
```

You can also run ".schema" from the sqlite command line to get an SQL description of the database schema.
