You just have to edit the "databases.yaml" file (you can use "edb" command in CLI) and define the JDBC connection properties, something like that : driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver" url = "jdbc:sqlserver://10.226.xxx.xxx" user: xxx password: xxx catalog: demo schema: dbo See https://doc.telosys.org/telosys-cli/cli-getting-started/model-creation/new-model-from-database NB: don't forget to put the jdbc jar file ( "sqljdbc.jar" ) in "TelosysTools/lib" See https://stackoverflow.com/questions/50156877/how-to-set-the-jdbc-driver-jar-in-telosys-cli-to-create-a-dbmodel
