# [[PHP MySQL Intro]]

## 🎯 한 줄 통찰 (One-line insight)
PHP combined with MySQL is explicitly framed as cross-platform in a specific direction — you can DEVELOP on Windows and SERVE on Unix — highlighting that the development and production environments don't need to match, a practical deployment flexibility called out from the very first chapter. [S1]

## 🧠 핵심 개념 (Core concepts)
- **MySQL** — a fast, free, widely-used database system, developed by Oracle Corporation, using standard SQL. [S1]
- **Table structure** — data stored in tables (columns + rows); a database groups related tables (e.g., Employees, Products, Customers, Orders). [S1]
- **Query** — a request for specific data, e.g. `SELECT LastName FROM Employees`. [S1]
- **Scale** — MySQL is the de-facto standard for huge-volume sites (Facebook, Twitter, Wikipedia scale) but also scales down to embedded use. [S1]

## 📖 세부 내용 (Details)
- Example query: `SELECT LastName FROM Employees` — selects all data in the LastName column. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — Facebook/Twitter/Wikipedia급 대용량 서비스가 MySQL을 사용한다는 점이 확장성의 근거로 제시된다. [S1]

## 💻 코드 패턴 (Code patterns)
해당 챕터는 개념 소개 중심으로 별도 PHP 코드 예제가 없음 — 다음 챕터([[PHP MySQL Connect]])에서 실제 연결 코드가 시작된다.

## ✅ 검증 상태 및 신뢰도
