>2000 words about arrays and tables
Merely 2000 words, we have a full complete book for that [1].

On one extreme people are going to bolt on everything on Postgresql database, and another extreme of integrating clunky disparate systems, D4M is a breath of fresh air that is based on mathematics not unlike the venerable SQL relational database concepts [3].
