Some notes on the exporting the data
-
Relations form a graph
-
- the nodes refer to the “real” data or contain some literal
- how the graph is represented in machine is immaterial for

-
Data export does not
necessarily mean physical
conversion of the data
-
- relations can be generated on-the-fly at query time
-
- via SQL “bridges”
- scraping HTML pages
- extracting data from Excel sheets
- etc.
