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/ferreteria/class
- handle multiple rows
- sequential - Template:L/ferreteria/class
- status (how many rows found)
- position row cursor
- access current row
- end-of-rowset flag
- indexed
- sequential - Template:L/ferreteria/class
Database sources:
- manage what's in the source (selected, sequential access)
Currently, Table (Source) objects define:
- name of single-row class (Template:L/ferreteria/class)
- name of database table or other SQL to access it (Template:L/ferreteria/class)
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)
