Installation Instructions
Normally, you can get drivers from DBNova's External Driver Management page—manual download is usually unnecessary.
If you download manually, extract the files and place them in the drivers folder without renaming:
Windows：
~/AppData/Roaming/com.ruiransoft.dbnova/udsdrivers/.Linux：
~/.config/com.ruiransoft.dbnova/udsdrivers/.MacOS：
~/Library/Application Support/com.ruiransoft.dbnova/udsdrivers/.
Note
DBNova's UDS drivers can be downloaded directly within the tool, but the underlying native libraries for the databases (e.g., DuckDB, IBM DB2, Oracle) must be downloaded separately.
You can save these native libraries (.dll, .so, .dylib) anywhere on your system. DBNova allows you to specify their exact file path when configuring the database connection.
Duckdb Library
https://github.com/duckdb/duckdb/releases
DBNova requires the DuckDB C API (Shared Library). Please download the libduckdb-<os>-<arch>.zip archive that matches your operating system (do not download the CLI tool).
IBM DB2 Library
Oracle DB Library
