Notes

Things in need of re-examination:

• interface ifSingleKeyedRow

• Standard storage-PortalRow class expects the Table to have the table name (via Template:L/ferreteria/class, but other constructions are possible.

rearrangement in progress

Core functionality:

• handle current row - Template:L/version
• handle multiple rows
  • sequential - Template:L/version
    • status (how many rows found)
    • position row cursor
    • access current row
    • end-of-rowset flag
  • indexed

Database sources:

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

Currently, Table (Source) objects define:

• name of single-row class (Template:L/version)
• name of database table or other SQL to access it (Template:L/version)

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)
