This is true, the site is not clear about the licenses. But, if you are using Xojo Web, you can download free VServer DB with 5 simultaneously connections and to use the Valentina DB ADK (API) for Xojo, to connect your Xojo Web Application with VServer DB, which it can run on the same machine. All of these are FREE.
For local DB on Desktop applications, you will need to get license for DB ADK (around $199).
If you want reporting engine, you will need to have at least a license for Studio Pro ($199) and if you want for local reports, also a license for Reports ADK (other $199). For VServer DB, it is not needed any licenses for the reports, except to have licensed version of the Studio Pro, for the reports creation.
If you want to distribute the database with your application together (on installer), you will need a special license VDN with cost around $600. But is it needed for client server application? No, it is not needed, because your customer can download the free version of VServer with 5 connections. If he needs more connections, then he will buy them direct from Valentina. ( Not good for me !!!)
For me, it took more than two weeks until to understand their licenses plan. Don’t forget, that you dont need to buy the Xojo Licenses for DB Access ($300). This is good for us.
I will agree with Oliver, that we need to push Xojo Company, to come in cooperation with Lynn and Ruslan, because they have a better database solution for local Database, rather using Sqlite.
Also, we need to push Ruslan, to provide a MySQL/Progress database access through the existing API (they have already access for the reporting API) . If you agree, write on that forum. Maybe, something will be good for all of us.
