Bikeshed common database API

We should provide a common interface for databases to ease porting from one database backend to another.

Similar projects for other languages:

• Python:
  • DB-API
  • SQLAlchemy
• Go:
  • sql
• Ruby:
  • DataObjects
  • Sequel
• Node.js:
  • Sequelize.js
• Java:
  • JDBC
• C++:
  • QtSql
  • SOCI
• Objective C:
  • Core Data
  • BaseTen (Seems to be offline)

Known bindings:

• Sqlite:
  • https://github.com/linuxfood/rustsqlite
• PostgreSQL (in progress):
  • https://github.com/erickt/rust-pg

Needed:

• MySQL
• Oracle

Open questions:

• Should we bother trying to support NoSQLs?
• Do we low-level like Python's DB-API? Or higher level, like Ruby's Sequel?
