[Qgis-user] Database options

[Alex M]

I looked for this unicorn many moons ago. It sadly doesn't exist. I have
not found any interface quite like Access (which I have successfully
used via ODBC to sqlite). Libre Base comes close but there's been many
years of them saying they'd implement sqlite as a 1st class db and no
movement, they always prefer Java based solutions it seems.

The conclusion I reached is that you need either a web or local
interface to your db. For data entry I looked into writing a custom
Python application with the widgets I wanted for data entry, a node type
app could work also (share code between a web interface and desktop
interface). One option would be to make custom forms, or a plugin for
QGIS and do all your data entry there.

For writing queries there's lots of GUI tools, I usually use Spatialite
GUI, QGIS QSpatialite Plugin, or Firefox SQLite Manager (non-spatial
queries only). But both of these would be terrible for mass data entry.

You could also, do a spreadsheet->csv->db script

Thanks,
Alex
