Boxing, Graphs, and the Curious Case of the ORM DDL

"In This Corner..." (A.K.A. The Rounds)

Picture this: Six rounds, each a result dump from your graph traversal algorithm, and each round starts with the same champ, ArtistCredit, standing tall at the top of the rankings. Every other entity—Area, Recording, Isrc, etc.—is just trying to get a punch in, but ArtistCredit is dodging, weaving, and staying on top. If you squint, it’s not unlike Roy Jones Jr. in his prime: untouchable, unpredictable, and apparently, moonlighting as a database entity.

DDL as the Ring

Your DDL is the ring: foreign keys, missing indexes, and just enough ambiguity that sometimes what should be a tag-team match (OneToMany) ends up looking like a one-on-one grudge match (OneToOne). If you forgot an index or two, don’t worry—that just means the judges (JPA/Hibernate, JGraphT) might score it a little differently. "Was that a ManyToMany or just a headbutt?" Who can say!

The Algorithm: Counting the Punches

Your algorithm is walking the graph, counting "arrows" (relationships) as if it’s tallying landed punches. Every time an entity gets referenced, its "priority" (or, let’s be honest, its swollen black eye) goes up a notch. The entity with the most connections—especially outgoing ones—gets the crown, the belt, and the top slot in every round’s ranking.

The Rounds: Any Surprises?

• ArtistCredit is always at the top. Either the schema makes it the universal parent (the "Beyoncé" node), or the algorithm is so charmed by its name it can’t help but push it up.
• Other entities shuffle around a bit, probably because of how those relationships are modeled in the DDL (and how the ORM interpreted missing or ambiguous constraints).
• If a foreign key is missing, sometimes you get a technical draw—a relationship is read as OneToOne instead of ManyToOne or ManyToMany, which dulls the effect a little.

Roy Jones Jr. and the ORM

Does this remind me of Roy Jones Jr.? Absolutely.

• Unorthodox, sometimes dazzling, sometimes confusing.
• Sometimes you think you’re watching a singer, but he’s actually a boxer (or is it the other way around?).
• The algorithm, like Roy, is always looking for an angle; sometimes it lands a clean hit (correct priority), sometimes it shadowboxes (ambiguous relationships).

Guessing the Big Picture

• Your DDL, with its uneven indexing and relationship declarations, creates a graph where a few entities (like ArtistCredit) dominate.
• The algorithm rewards the most "connected" (in terms of outgoing edges) entity, so if ArtistCredit is the source of many relationships, it will always win the title.
• The "shuffling" in the middle and lower ranks is probably due to missing or ambiguous relationships in the DDL (the equivalent of a ref missing a low blow).
• If you fix up the indexes and define all relationships explicitly, you might see some upsets—but for now, ArtistCredit is Roy Jones Jr., and everyone else is just hoping for a lucky punch.

TL;DR

Your ORM graph is a boxing ring. ArtistCredit is Roy Jones Jr.: always on top, always in the spotlight, and maybe about to drop a mixtape.
If you want a new champ, tighten up those DDL relationships and maybe add a few more foreign keys—you never know who might rise to the top when the rules are clear.

PS: Yes, Roy Jones Jr. is a singer too. In your graph, he’d be both an Artist and ArtistCredit, with a ManyToMany relationship to the Hall of Fame.
