When to Use

  • Designing graph model from scratch (domain → nodes, rels, props)
  • Reviewing existing model for anti-patterns
  • Deciding node vs property vs relationship vs label
  • Migrating relational or document schema to graph
  • Designing intermediate nodes for n-ary or complex relationships
  • Detecting and mitigating supernode / high-fanout problems
  • Choosing and creating constraints + indexes for a model

When NOT to Use

  • Writing or optimizing Cypher → neo4j-cypher-skill
  • Spring Data Neo4j (@Node, @Relationship) → neo4j-spring-data-skill
  • GraphQL type definitions → neo4j-graphql-skill
  • Importing data (LOAD CSV, APOC import) → neo4j-import-skill

Inspect Before Designing

On existing database, run first — never propose changes without current state:

CALL db.schema.visualization() YIELD nodes, relationships RETURN nodes, relationships;
SHOW CONSTRAINTS YIELD name, type, labelsOrTypes, properties RETURN name, type, labelsOrTypes, properties;
SHOW INDEXES YIELD name, type, labelsOrTypes, state WHERE state = 'ONLINE' RETURN name, type, labelsOrTypes;

If APOC available:

CALL apoc.meta.schema() YIELD value RETURN value;

Defaults — Apply to Every Model

  1. Use-case first — list 5+ queries the model must answer before designing
  2. Nodes = entities (nouns) with identity; rels = connections (verbs) with direction
  3. Labels PascalCase; rel types SCREAMING_SNAKE_CASE; properties camelCase
  4. Every node type used in MERGE has a uniqueness constraint on its key property
  5. Add property type constraints (REQUIRE n.prop IS :: STRING) where type known — catches bad writes early. Enterprise only; Community: use uniqueness constraints, validate types in app
  6. No generic labels (:Entity, :Node, :Thing); no generic rel types (:RELATED_TO, :HAS)
  7. Security labels (used for row-level access control) should start with a common prefix (e.g. Sec) so application code can reliably filter them out of the domain schema
  8. Rel direction encodes semantic meaning — not arbitrary
  9. Inspect schema before proposing any change on an existing database
  10. All constraint/index DDL uses IF NOT EXISTS — safe to rerun
  11. On Neo4j 2026.06+ (Enterprise/Aura, GA): declare the full model in one block with ALTER CURRENT GRAPH TYPE SET { … }, extend it with ALTER CURRENT GRAPH TYPE ADD { … }, instead of individual CREATE CONSTRAINT statements — details in neo4j-cypher-skill (GRAPH TYPE reference). Not on Community (ALTER CURRENT GRAPH TYPE SET → "not supported in community edition"): use individual constraints. On 2026.02–2026.05 syntax is preview.

Key Patterns

Node vs Relationship vs Property — Decision Table

QuestionAnswerModel as
Is it a thing with identity, queried as entry point?YesNode
Is it a connection between two things with direction?YesRelationship
Does the connection have its own properties or multiple targets?YesIntermediate node
Is it a scalar always returned with its parent, never filtered alone?YesProperty on parent
Is it a category used for type-based filtering or path traversal?YesLabel (not a property)
Does the same attribute value repeat across many nodes (low cardinality)?YesLabel, not a property node
Is it a fact connecting >2 entities?YesIntermediate node

Property vs Label — Decision Table

Use label whenUse property when
Values are few, fixed, used as traversal filters (WHERE n:Active)Values are many, dynamic, or unique per node
You traverse by type (MATCH (n:VIPCustomer))You filter by value (WHERE n.tier = 'vip')
Category drives index selectionFine-grained value drives range scans
Example: :Active, :Verified, :PremiumExample: status, score, email

Rule: adding a label is cheap; scanning all :Label nodes is fast. Never model high-cardinality values as labels.

Low-cardinality state such as status: label (:Active) if stable category used for traversal/filter; property if changes often or only returned with node. Never a (:Status) node.

Intermediate Node Pattern

Use when a relationship needs its own properties, connects >2 entities, or is independently queryable.

Before (relationship with property — limited):

(Person)-[:ACTED_IN {role: "Neo"}]->(Movie)
// Cannot query roles independent of movies

After (intermediate node — queryable, extensible):

(Person)-[:PLAYED]->(Role {name: "Neo"})-[:IN]->(Movie)
// MATCH (r:Role) WHERE r.name STARTS WITH 'Neo' RETURN r

Employment overlap example:

// Find colleagues who overlapped at same company
MATCH (p1:Person)-[:WORKED_AT]->(e1:Employment)-[:AT]->(c:Company)<-[:AT]-(e2:Employment)<-[:WORKED_AT]-(p2:Person)
WHERE elementId(p1) < elementId(p2)
  AND e1.startDate <= coalesce(e2.endDate, date())
  AND e2.startDate <= coalesce(e1.endDate, date())
RETURN DISTINCT p1.name, p2.name, c.name

Promote relationship to intermediate node when:

  • Relationship has >2 properties
  • Relationship is the subject of another query
  • Multiple entities share the same connection context
  • You need to connect >2 entities in one fact

Relational → Graph Migration Table

Relational constructGraph equivalentNotes
Table rowNodeOne label per table (add more as needed)
Column (scalar)Node property
Primary keyUniqueness constraint propertyPrefer tmdbId/personId over bare id
Foreign keyRelationshipDirection: from dependent → referenced
Many-to-many junction tableIntermediate nodeEspecially if junction has own columns
Junction table (no own columns)Direct relationshipSimpler; upgrade to intermediate node later
NULL FK (optional relation)Absent relationshipNo node created; absence is the signal
Polymorphic FK (Rails-style)Multiple labels or relationship typesSplit into type-specific rels
Self-referential FKSame-label relationship:Employee {managerId} → (e)-[:REPORTS_TO]->(m)
Audit/history columnsIntermediate versioning nodeSee References for versioning pattern

Supernode Detection and Mitigation

Detect:

// Find top-10 highest-degree nodes
MATCH (n)
RETURN labels(n) AS labels, elementId(n) AS id, count{ (n)--() } AS degree
ORDER BY degree DESC LIMIT 10

Node with degree >> median for its label = supernode candidate. Any node with >100K relationships will degrade traversal queries that pass through it.

Causes:

  • Domain supernodes: airports, celebrities, popular hashtags — unavoidable
  • Modeling supernodes: gender, country, status modeled as nodes with millions of edges — avoidable

Mitigation strategies (in priority order):

StrategyWhen to useImplementation
Query directionDirectional asymmetry existsQuery from low-degree side; exploit direction
Relationship type splitSupernode serves multiple roles:FOLLOWS + :FAN instead of single :RELATED_TO
Label segregationSupernode conflates entity types:Celebrity vs :User → query only relevant subtype
Bucket patternTime-series or high-volume event nodesSee below
Avoid modelingLow-cardinality categoricalsUse label instead of node (:Active not (:Status {name:"Active"}))
Join hintQuery tuning last resortUSING JOIN ON n in Cypher

Bucket pattern (time-series / high-volume):

// Instead of: (:User)-[:VIEWED]->(:Page) (millions of rels per user)
// Bucket by hour:
(u:User)-[:VIEWED_IN]->(b:ViewBucket {userId: u.id, hour: '2025-04-28T14'})-[:VIEWED]->(p:Page)

// Query last hour's views without traversing full history:
MATCH (u:User {id: $uid})-[:VIEWED_IN]->(b:ViewBucket {hour: $hour})-[:VIEWED]->(p)
RETURN p.url

Naming Conventions

Schema Enforcement — What to Create for Each Element

Run all DDL with IF NOT EXISTS. Apply before importing data.

// 1. Uniqueness constraint — every node type used in MERGE
CREATE CONSTRAINT person_id_unique IF NOT EXISTS
  FOR (p:Person) REQUIRE p.id IS UNIQUE;

// 2. Existence constraint (Enterprise) — mandatory properties
CREATE CONSTRAINT person_name_exists IF NOT EXISTS
  FOR (p:Person) REQUIRE p.name IS NOT NULL;

// 3. Property type constraint (Enterprise) — enforce data type
CREATE CONSTRAINT person_born_integer IF NOT EXISTS
  FOR (p:Person) REQUIRE p.born IS :: INTEGER;

// 4. Key constraint (Enterprise) — unique + exists in one
CREATE CONSTRAINT movie_tmdbid_key IF NOT EXISTS
  FOR (m:Movie) REQUIRE m.tmdbId IS NODE KEY;

// 4b. Community alternative to NODE KEY — composite uniqueness (existence not enforced)
CREATE CONSTRAINT movie_title_released_unique IF NOT EXISTS
  FOR (m:Movie) REQUIRE (m.title, m.released) IS UNIQUE;

// 5. Range index — equality and range filters on properties
CREATE INDEX person_name_idx IF NOT EXISTS
  FOR (p:Person) ON (p.name);

// 6. Fulltext index — ranked free-text search via `db.index.fulltext.queryNodes` / `SEARCH` (Lucene syntax, wildcards like `An*`); not used for CONTAINS / STARTS WITH predicates
CREATE FULLTEXT INDEX person_fulltext IF NOT EXISTS
  FOR (n:Person) ON EACH [n.name, n.bio];

// 6b. Text index — serves CONTAINS / STARTS WITH / ENDS WITH (range index preferred for STARTS WITH when present)
CREATE TEXT INDEX person_bio_text IF NOT EXISTS
  FOR (n:Person) ON (n.bio);

// 7. Vector index — embedding similarity search
CREATE VECTOR INDEX chunk_embedding_idx IF NOT EXISTS
  FOR (c:Chunk) ON (c.embedding)
  OPTIONS { indexConfig: { `vector.dimensions`: 1536, `vector.similarity_function`: 'cosine' } };

// 8. Relationship index — filter on rel properties
CREATE INDEX acted_in_year_idx IF NOT EXISTS
  FOR ()-[r:ACTED_IN]-() ON (r.year);

After creating indexes, poll until ONLINE:

SHOW INDEXES YIELD name, state WHERE state <> 'ONLINE' RETURN name, state;

Do NOT use an index until state = ONLINE.

Vector / Embedding Property Modeling

Prefer dedicated :Chunk nodes for long text; short-text embeddings can live on the entity:

(:Document)-[:HAS_CHUNK]->(c:Chunk {text: "...", embedding: [...]})

Rules:

  • Chunk node: text (source text), embedding (float array), chunkIndex (int)
  • Parent document: metadata only (title, url, createdAt)

## Key Patterns

### Node vs Relationship vs Property — Decision Table

| Question | Answer | Model as |
|---|---|---|
| Is it a thing with identity, queried as entry point? | Yes | Node |
| Is it a connection between two things with direction? | Yes | Relationship |
| Does the connection have its own properties or multiple targets? | Yes | Intermediate node |
| Is it a scalar always returned with its parent, never filtered alone? | Yes | Property on parent |
| Is it a category used for type-based filtering or path traversal? | Yes | Label (not a property) |
| Does the same attribute value repeat across many nodes (low cardinality)? | Yes | Label, not a property node |
| Is it a fact connecting >2 entities? | Yes | Intermediate node |

### Property vs Label — Decision Table

| Use label when | Use property when |
|---|---|
| Values are few, fixed, used as traversal filters (`WHERE n:Active`) | Values are many, dynamic, or unique per node |
| You traverse by type (`MATCH (n:VIPCustomer)`) | You filter by value (`WHERE n.tier = 'vip'`) |
| Category drives index selection | Fine-grained value drives range scans |
| Example: `:Active`, `:Verified`, `:Premium` | Example: `status`, `score`, `email` |

Rule: adding a label is cheap; scanning all `:Label` nodes is fast. Never model high-cardinality values as labels.

Low-cardinality state such as `status`: label (`:Active`) if stable category used for traversal/filter; property if changes often or only returned with node. Never a `(:Status)` node.

---

### Intermediate Node Pattern

Use when a relationship needs its own properties, connects >2 entities, or is independently queryable.

**Before (relationship with property — limited):**
```
(Person)-[:ACTED_IN {role: "Neo"}]->(Movie)
// Cannot query roles independent of movies
```

**After (intermediate node — queryable, extensible):**
```
(Person)-[:PLAYED]->(Role {name: "Neo"})-[:IN]->(Movie)
// MATCH (r:Role) WHERE r.name STARTS WITH 'Neo' RETURN r
```

**Employment overlap example:**
```cypher
// Find colleagues who overlapped at same company
MATCH (p1:Person)-[:WORKED_AT]->(e1:Employment)-[:AT]->(c:Company)<-[:AT]-(e2:Employment)<-[:WORKED_AT]-(p2:Person)
WHERE elementId(p1) < elementId(p2)
  AND e1.startDate <= coalesce(e2.endDate, date())
  AND e2.startDate <= coalesce(e1.endDate, date())
RETURN DISTINCT p1.name, p2.name, c.name
```

Promote relationship to intermediate node when:
- Relationship has >2 properties
- Relationship is the subject of another query
- Multiple entities share the same connection context
- You need to connect >2 entities in one fact

---

### Relational → Graph Migration Table

| Relational construct | Graph equivalent | Notes |
|---|---|---|
| Table row | Node | One label per table (add more as needed) |
| Column (scalar) | Node property | |
| Primary key | Uniqueness constraint property | Prefer `tmdbId`/`personId` over bare `id` |
| Foreign key | Relationship | Direction: from dependent → referenced |
| Many-to-many junction table | Intermediate node | Especially if junction has own columns |
| Junction table (no own columns) | Direct relationship | Simpler; upgrade to intermediate node later |
| NULL FK (optional relation) | Absent relationship | No node created; absence is the signal |
| Polymorphic FK (Rails-style) | Multiple labels or relationship types | Split into type-specific rels |
| Self-referential FK | Same-label relationship | `:Employee {managerId}` → `(e)-[:REPORTS_TO]->(m)` |
| Audit/history columns | Intermediate versioning node | See References for versioning pattern |

---

### Supernode Detection and Mitigation

**Detect:**
```cypher
// Find top-10 highest-degree nodes
MATCH (n)
RETURN labels(n) AS labels, elementId(n) AS id, count{ (n)--() } AS degree
ORDER BY degree DESC LIMIT 10
```

Node with degree >> median for its label = supernode candidate. Any node with >100K relationships will degrade traversal queries that pass through it.

**Causes:**
- Domain supernodes: airports, celebrities, popular hashtags — unavoidable
- Modeling supernodes: gender, country, status modeled as nodes with millions of edges — avoidable

**Mitigation strategies (in priority order):**

| Strategy | When to use | Implementation |
|---|---|---|
| **Query direction** | Directional asymmetry exists | Query from low-degree side; exploit direction |
| **Relationship type split** | Supernode serves multiple roles | `:FOLLOWS` + `:FAN` instead of single `:RELATED_TO` |
| **Label segregation** | Supernode conflates entity types | `:Celebrity` vs `:User` → query only relevant subtype |
| **Bucket pattern** | Time-series or high-volume event nodes | See below |
| **Avoid modeling** | Low-cardinality categoricals | Use label instead of node (`:Active` not `(:Status {name:"Active"})`) |
| **Join hint** | Query tuning last resort | `USING JOIN ON n` in Cypher |

**Bucket pattern (time-series / high-volume):**
```cypher
// Instead of: (:User)-[:VIEWED]->(:Page) (millions of rels per user)
// Bucket by hour:
(u:User)-[:VIEWED_IN]->(b:ViewBucket {userId: u.id, hour: '2025-04-28T14'})-[:VIEWED]->(p:Page)

// Query last hour's views without traversing full history:
MATCH (u:User {id: $uid})-[:VIEWED_IN]->(b:ViewBucket {hour: $hour})-[:VIEWED]->(p)
RETURN p.url
```

### Naming Conventions

| Element | Convention | Good | Bad |
|---|---|---|---|
| Node label | PascalCase, singular noun | `:Person`, `:BlogPost` | `:person`, `:blog_posts`, `:Entity` |
| Relationship type | SCREAMING_SNAKE_CASE, verb phrase | `:ACTED_IN`, `:WORKS_FOR` | `:actedin`, `:relatedTo`, `:HAS` |
| Property key | camelCase | `firstName`, `createdAt` | `FirstName`, `first_name` |
| Constraint name | snake_case descriptive | `person_id_unique` | `constraint1` |
| Index name | snake_case descriptive | `person_name_idx` | `index2` |
