Why stop at relational, we should go all the way to include spreadsheets, matrices and graphs as in D4M [1].

D4M can caters to most modern data abstractions including spreadsheets, database tables, matrices, and graphs based on associative arrays [2].

>For software engineers, databases are one of the biggest power tools available to us, up there with compilers and full featured operating systems.

D4M team even proposed a new and elegant associative array based operating system namely TabulaROSA that probably can settle the monolithic vs micro kernel debates by Torvalds and Tanenbaum for good [3].

That left us with a powerful programming language to go with them. As a comprehensive programming toolkit nothing come even close to D language in term expressiveness with its Compile Time Function Evaluation (CTFE) features among others that Zig and C++20 are blatantly copying [4].
