Core functionality:

Database sources:

  • manage what's in the source (selected, sequential access)

Currently, Table (Source) objects define:

There are two types of accessible data, when dealing with databases:

  • data that has been loaded into a black-box "resource" rowset, and can be accessed sequentially
  • data that is being stored in memory, and can be accessed by index (core functionality)
