When does data initialization occur in virtual tables?

In Android, virtual tables (for example, in ContentProvider using SQLite) are initialized upon the first access to them, when a data query occurs. Data initialization happens at the moment of calling methods such as query(), insert(), update(), or delete(), when the system accesses the virtual table to retrieve or modify data.

That is, data is not loaded in advance but prepared and initialized "on the fly" during the first request, which helps optimize resource usage and work with dynamic data.
