I remember when a million customers records was a good size database...not so much today. I talked about Big Data recently . In this article Programming languages: Julia touts its speed edge over Python and R . They mention a benchmark that looks at Apple stock price states - open, high, low and close – using a 2.5GB dataset with 50 million rows and five columns. Fifty million rows...Wow! With the Internet and computers everywhere, data growth is rampant.
