Data Model

Bases are workspaces. List bases to get base_id (appXXXXXXXXXXXXXX format).
Tables live in bases. Use base_id plus table name or tblXXX id for record operations.
Records have fields (column values). Linked records store arrays of record ids. Attachments use {url} objects.
Hierarchy: base_id → table_id → record_id. All record ops require base and table.
