Postgresql – Newbie IT student. Question about a homework assignment

I'm a new student in an IT program, and I'm trying to make sense of what this means:

Design for the following non-functional business problem:

Your business delivers Internet services, by deploying compute
infrastructure into rented data centers, which have transit
partnerships. In order to sustain these services, it is important to
track all of the infrastructure, so that the status of it may be
communicated to the applications which rely on it, and in order to
manage it. It is moving beyond the scope of a single spreadsheet,
which one person can administer, and needs to go into a database for
concurrent access before a infrastructure management platform can be
selected.

There are going to be up to 10 data centers, each with 2 to 4 transit
providers.

Each data center has between 2 and 50 racks, and two core routers.

Each rack has 2 power supplies, 2 switches, 1 storage shelf (4U) and
20 spaces for 1U servers.

Each storage shelf has 48 SAS SSDs, and each 1U server has 12 SSDs.

Use modeling to conclude a relational database design which can
migrate this need out of a single spreadsheet. Provide evidence of
the design, by submitting the PostgreSQL DDL. An export of a
spreadsheet will be provided, and sample python for populating a given
model.

A data set for populating your database, can be found at:
infrastructure.tgzView in a new window

Of course, it is a compressed tar file which contains the following
files: uplinks.csv, infrastructure.csv, and media.csv.

Data model designs with less abstraction will be the easiest to
populate with these data. Focus on pulling out a simple sample of the
data, in order to prove the population of the set of tables by mapping
the natural keys, to generated primary and foreign keys.

Now, the class is fine and good and the instructor is funny and intelligent, but I'm not sure what to do as the pace moves a bit quicker than a baby programmer is used to. Would the following steps be right?

1. Go into Violet UML Editor and craft the database
2. Export this model into something
3. Go into the Postgres I set up in linux
4. use the database our instructor set up, and link that to the assignment

I'm not looking for someone to do my homework, but an explanation of the underlying concepts and some links would be amazing.
