Today they have patron saints for everything from accountants to yachtsmen . . .
The Partron Saint of Database Management
It’s true, the Catholic Church has noted that St. Isadore is the Patron Saint of all things Computers:
St. Isadore: The Patron Saint of computers
Others say that it's more accurate to note that St. Isadore is the Patron Saint of the Internet:
Pray to St. Isadore
Jesus is my DBA
While there is no Patron Saint specifically for database management, so many database folks say that Jesus is their DBA:
Jesus is my DBA
Jesus was a carpenter, but he would have been a good DBA, for many reasons . . .
