For example you have in MySQL/MariaDB or PostgreSQL two databases called VendorAccounts and Inventory. Your query/view/function/etc. must access one table in each to get the relevant data. (MariaDB is a FOSS fork of MySQL and can easily replace MySQL) My first question is what is your backend? Next how are you connecting to the backend? For example MySQL/MariaDB have several possibilities depending on the network and database server location. I have MySQL/MariaDB installed on my desktop and can access it using direct connection, odbc, and jbdc - I normally use direct connection. Also, have you checked the documentation for your backend for the syntax for querying tables in different databases? MySQL/MariaDB use the SQL union to do this.
