docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동
최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

# [[SQL Tutorial]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
Map of Content (MOC) for the W3Schools SQL Tutorial — the root that links every SQL knowledge page in this topic folder. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- This folder (`Topic_SQL`) wikifies the **W3Schools SQL Tutorial** (left-sidebar tutorial menu), one knowledge page per document, in P-Reinforce v3.1 format — following the same convention as `Topic_HTML` / `Topic_CSS` / `Topic_JavaScript`. [S1]
|
||||
- Scope: **tutorial + "Learning by examples" pages only**. The large reference dumps (SQL Keywords Reference, MySQL/SQL Server/MS Access Functions — ~290 individual function-stub pages) and non-knowledge meta pages (Quiz, Exercises, Editor, Certificate, Bootcamp, Syllabus, Study Plan, Training, Server) are **excluded by design**. [S1]
|
||||
- **Progress:** **67 of 67 planned docs complete — SQL category done.**
|
||||
- Every page roots its Knowledge Graph back to this `[[SQL Tutorial]]` node.

## 🛠️ 적용 사례 (Applied in summary)
|
||||
67 knowledge documents generated, all grounded in the corresponding W3Schools pages via a Playwright-based extraction pipeline (adapted from the Datacollector_MAC project's `web_extract.mjs`, with added noise-stripping for sidebar/footer).
|
||||
|
||||
## ✅ 검증 상태 및 신뢰도
|
||||
- **상태:** draft
|
||||
- **검증 단계:** conceptual
|
||||
- **출처 신뢰도:** B (W3Schools — widely used educational reference)
|
||||
- **신뢰 점수:** 0.90
|
||||
- **중복 검사 결과:** 신규 생성 (New discovery)
|
||||
|
||||
## 🔗 지식 그래프 (Knowledge Graph)
|
||||
- **상위/루트:** [[10_Wiki]]
|
||||
- **관련 개념:** [[SQL Intro]], [[SQL Select]], [[SQL Create Table]], [[Topic_Programming]]
|
||||
- **참조 맥락:** HTML/CSS/JavaScript에 이어 W3Schools 지식화 시리즈의 다음 카테고리. 완료 후 Python/PHP/MySQL 등 나머지 카테고리가 동일한 규칙으로 이어진다.
