Dear client, if you use database replication it is not a problem, I am a Mysql expert with 5+ years of experience. I have a lot of experience in function, procedure, trigger, foreign key, primary key, and etc,,,,,I have experience using mysql functions or procedures to reduce the actual coding and increase the speed by more than 100 times. I can do everything about RD, not just the mysql data base. I would like to seriously discuss RD once. Regards.
