Joget DX 8 Stable Released
The stable release for Joget DX 8 is now available, with a focus on UX and Governance.
The article you mentioned seems to give an example storing data using JDBC. So using standard JDBC there's no restriction in connecting to external or multiple databases.
From this reference http://dev.joget.org/community/display/KBv4/Store+Form+Field+Data+to+Multiple+Tables
jobget support multiple tables. I am looking for feature connecting to multiple database
Could you please provide steps how to connect to multiple database through Joget workflow
