tokyocabinet,redis,mongodb,couchdb,influxdb,timescaledb connectors.

[Alain De Vos]

In our modern time there are also modern databases.
But for connecting one needs a connector.
I wander to which databases I can connect with ada.

Well if I can connect to python I might have a very ugly-workaround.
But how do I connect to python ?

	Since Python is a (byte-code) interpreted programming language in its
own right, you could design some interprocess communication protocol, write
handlers for said protocol in Ada and Python, and run the Python stuff in a
separate process.

	Or, you study the section of the Python manual regarding embedding the
language in another application -- and write an interface layer in Ada to
access the embedded mode API (which is documented for C language
programming, so your interface layer is going to look a lot like a binding
to any other C-language library):
https://docs.python.org/3/extending/embedding.html

	Of course, you'll need the proper db-api adapter for Python to use
whatever DBMS you are targeting.

If connector means DB client then this is wrong. Embeddable databases 
like tokyocabinet and SQLite need none, the DBMS is a part of your program.

All of them.

Python has appropriately ugly and buggy API. It is no problem to call 
Python from Ada. I have Ada applications running Python scripts.

Apparently GNATCOLL has some database bindings, but I never got them to work. (64bit Windows, 32bit GNAT, 64bit Postgres was my setup back then IIRC; I suspect it had to do with the difference in 32- and 64-bit.)

I think Dmitry's Simple Components has a ODBC interface.

And there's an all-Ada graph-database called MNESON that I'm poking at to try to use Ada.Containers rather than the containers it's using.

gnatcoll has normally sqlite and postgres. 
But sqlite,postgres,mysql is the "usual stuff"

Did you manage to do that?

Today I put Mneson on GitHub, including an adaptation of the 2005 code to build on present GNAT, but still with the non standard container lib.

(mysql,postgresql,sqlite)

others like ms sql-server -> ODBC

Oracle -> ODBC or native OCI.
OCI is easier via ocilib

All connectors seem to be oriented towards relation databases ?

Sorry I did not see the buzzwords in the subject.

It's nice to have connectors to relation databases.
But currently people are also developing query languages providing security or functionality on top of the sql-"text"-language.
