• GOAL: SAGE Enhancement Proposal.
  • Unified Database class
    • init establishes connection to sqlite
    • create, remove and modify tables
  • Query class
    • has an instance of the database class as a `parent'
    • has a query string
    • think about recursive searching without actually calling sqlite every time
• Issues to brainstorm:
  • Brainless database creation.

  • 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]

  • Uniform database approach within sage
  • 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 immutable
