I am looking to implement ignition with a database for the first time. My question concerns whether to use a free or purchased database. I have completed projects in the past with Wonderware using a MS SQL Express database. I have started getting familiar with MYSQL which seems fairly straight forward.
At what point do you need to go with a purchased database? I understand SQL express has data limits but I have found nothing on limits about MYSQL.
The database portion of the project is to log approximately 500 data points every 5 minutes 24 hours a day 7 days a week 365 days a year.
