Data in RDBMS

[kylecordes]

There have been (off-line) requests to make this example application slightly more realistic across the stack, by moving the data displayed out of JSON files (served by a piece of development tooling, json-server) into RDBMS tables.

Most likely choice, PostgreSQL.

Most likely this will involve creating a few tables and a way of populating them with fake data, in the "employee management system" example problem domain used here. Alternatively, if there is some kind of example RDBMS data out there that could be used, it will be possible to edit the problem domain here a bit to match.
