Data Trinity: Graphs of Data (Part 1.1)

The Essentails in my Domain and The Power of Graphs

When modeling a domain, I ask myself the following questions:

• What are the dominant nouns in my domain?

• Do these nouns combine to other nouns?

Spotify Example

What are the dominant nouns on Spotify?

Listener, Artist, Song

Do these nouns combine to other nouns?

Album = Artist + Song

Playlist = Listener + Song

Shared Playlist = Playlist + Listener

Spotify knows hundreds of those combined entities.

What we see here is a combinatorial explosion. This is the reason a lot of software projects fail. The number of entities increases until the software engineers cannot handle them anymore.

The next article will name the edges in the graph and give entites attributes.
