MapReduce has been proven as a technique for high-scale data analysis by Internet leaders such as Google and Yahoo. Greenplum gives enterprises the best of both worlds—MapReduce for programmers and SQL for DBAs—and will execute both MapReduce and SQL directly within Greenplum’s Parallel Dataflow Engine (Figure 10), which is at the heart of the database. Greenplum MapReduce enables programmers to run analytics against petabyte-scale datasets stored in and outside of Greenplum Database.

SQL was one of the first commercial languages for Edgar F. Codd's relational model, as described in his influential 1970 paper, "A Relational Model of Data for Large Shared Data Banks". Despite not adhering to the relational model as described by Codd, it became the most widely used database language. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements. SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standards (ISO) in 1987.

Isn’t there anything else that I could be doing that would be more beneficial to me, my family, or the human race? Well, of course there is. The fact is, however, I generally love relational databases, I love to write, and I want to help other people get better at what they do. When I was first getting started designing databases, I learned from a few great mentors, but as I wanted to progress, I started looking for material on database design, and...
