Yes, I know that sqlite supports transactions. However, this is not possible when working with him in LAMW. I think it makes sense. It is also bad that block processing of requests goes in different transactions. It would be advisable to conduct them in a single transaction. It would be faster to maintain data integrity. Also, it would be good to update the database in one transaction. Otherwise, in the event of a failure in one request, the entire database will be in an incomprehensible state. And further. I have not found anywhere documenting the database updating tool. I only saw this in the source code on java. When does this update start?
