This tweet from former MySQL AB CEO Mårten Mickos caught my eye. It shows a trend of increased demand for MySQL and PostgresSQL expertise while job postings on job websites for those with Oracle and Ingres expertise declined.
I was a little shocked by the graph until you realize it’s just a trend. I then looked at the absolute number of jobs requesting database expertise and the story quickly becomes clear….
So if you are looking for a DB admin job the overall number of jobs in that sector are overwhelmingly Oracle jobs but the growth is in MySQL and PostgresSQL expertise.
