I want to release a spring boot web application together with a Postgres database. For the installation at the customer, i want to use Install4J.
Are there any best practices to install the two systems at once? Should i separate the two installers and let the customer install one system after the other?
I want to keep it a simple as possible, as the customer is not a person with a strong technical background.
What about licence issues? Do i have to provide the Postgres licence also in my application?
