+# [[Python MongoDB Create Collection]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+A MongoDB collection maps conceptually to a SQL table, but exhibits the same lazy-creation behavior as the database itself — it isn't created until a document is actually inserted into it. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Collection** — MongoDB's equivalent of a SQL table. [S1]
+- **`mydb["collectionname"]`** — references (but doesn't yet create) a collection. [S1]
+- **Lazy creation** — the collection isn't created until a document is inserted. [S1]
+- **`mydb.list_collection_names()`** — lists all collections in a database, for existence checks. [S1]
+
+## 📖 세부 내용 (Details)
+- Reference a collection: `mycol = mydb["customers"]`. [S1]
+- List collections: `print(mydb.list_collection_names())`. [S1]
+- Check specific collection: `collist = mydb.list_collection_names(); if "customers" in collist: print("The collection exists.")`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — Insert Document 챕터에서 실제 문서를 삽입해야 컬렉션이 진짜로 생성된다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Reference and check a collection (Python):
+```python
+mycol = mydb["customers"]
+collist = mydb.list_collection_names()
+if "customers" in collist:
+    print("The collection exists.")
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.88
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[Python Tutorial]]
+- **관련 개념:** [[Python MongoDB Create DB]], [[Python MongoDB Insert]], [[SQL Create Table]]
+- **참조 맥락:** SQL 테이블에 대응하는 MongoDB 컬렉션 — 마찬가지로 지연 생성됨.
