[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. ## 📚 출처 (Sources) - [S1] W3Schools — Python MongoDB Create Collection — https://www.w3schools.com/python/python_mongodb_create_collection.asp ## 📝 변경 이력 (Change history) - 2026-07-04: Initial draft synthesized from the W3Schools "Python MongoDB Create Collection" page (Astra wiki-curation, P-Reinforce v3.1 format).
