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