• GOAL: SAGE Enhancement Proposal.
  • unified Database class
    • init establishes connection to sqlite
    • create, remove and modify tables
    • copy method - when should this create a new database file?
    • print?, save and show?
    • recursive queries without actually calling sqlite every time
    • query in place, query that creates a new Database object
  • Brainless database creation.
  • Databases distributed with sage
  • Online databases
    • cgi web-accessible...
    • accessible from SAGE, perhaps hosted at sage.math...
    • SQLite servers?
  • Automagic caching: keep track of computation results
    • keeping those results in portable objects, making these objects merge-able, etc...

  • Licensing: ∃ DBGPL?

  • Noticing identical database entries
  • Standard databases included with sage should be immutable

  • SAGE [http://www.initd.org/pub/software/pysqlite/doc/usage-guide.html interface] to sqlite [:sqlite-tutorial: creating your own database using sqlite in sage]
