MongoDB with Play! 채수원 (LG CNS) doortts@gmail.com Revision: 2011.6.17 2011 JCO 11th Conference | Track2-Session5 | Javacommunity.Org

Who am I Role - LG CNS 전문기술교육팀 전임강사 - LG CNS Agile Coach Specialty - 객체지향 설계 - 애자일 개발 - 팀 생산성 향상 Book -TDD실천법과 도구 (2010,한빛미디어)

Why am I here? 목적 웹 서비스를 개발하는 방식에 대해 되짚어 보고 ‘생산성’이라는 측면에 대해서 생각해 본다. 목표 - MongoDB와 Play 프레임워크의 컨셉을 이해한다. - 특징적인 기능들을 간략히 살펴본다. - 짧은 시간안에 서비스를 만들어 내는 어떤 방식을 살펴본다.

My personal dev era...PHP 개발(in my opinion)- Easy to learn and use- First 5 pages for 5 hours (exclude design works)

My personal dev era...Java기반 웹 개발로 전환...

My personal dev era...I need...

여기에는 사실...

Front-end 기술들은 제외하고!

우리의 관심을 분산시키는이런저런 기술들도 제외하고!

We are here IT Universe

My personal dev era...Java 기반 웹 개발(in my opinion)- NOT easy to learn and use- First 5 pages for 50 hours !!

Someone says… No Pain, No Gains !

No!!! No More Pain!!

잠깐! 그런데,우리가 지금뭘 하고 싶은 거죠?

Developing WEB

over1000 projects / year

New kids on the street

In cases...

Idea  Time  Service

Productivity focused Big Hits!!

Productivity focused

Productivity focused ???

Productivity focused in Java http://playframework.org

‘Play!’의 목표 be productive quickly and efficiently

GWT Rails Grails Play!http://raibledesigns.com/rd/entry/open_source_web_frameworks_mailing

Key features• Fix the bug and hit reload!• Stateless model (Ready for REST)• Efficient template system(based on Groovy)• Asynchronous (long polling and WebSockets)• Full stack integration with Hibernate, OpenID, OAuth, Memcached…• Pure Java• Resolve errors quickly• Fun & Productive

생각해 볼 문제들 - 장점과 단점? - 성능은?

And Then...

We Need Box and Line!!• JPA?• JDBC?• RDBMS... MSSQL? ORACLE? MySql? PostgreSQL?Which one is easiest one to development with?

My personal dev era... SQL & PL/SQL (in my opinion) - Not hard, but there is need time to learn and use - and, so many spoilers...

What is MongoDB?MongoDB (from "humongous") is a scalable, high-performance, open source, document-oriented database. (Written in C++)

Why MongoDB?• Easy to learn and use• No! SQL !!!• JavaScript• JSON-like Document• Open Source• Scalability

Key features• Document-oriented storage• Full Index Support• Replication & High Availability• Auto-Sharding• Querying• Fast In-Place Updates• Map/Reduce• GridFS• Commercial Support

And ...

Easy to Try on Online~!

Easy to run• 압축을 푼다.• mongod• 끝!

Real World Example Message Board 만들기 in 10min powered by Play! and mongoDB

CAUTIONS!!“우리는 종종 우리에게 적합한 기술이 아니라, 우리가 쓰고 싶은 기술을 사용하기 위해 욕심(desire)을 부린다. ‘욕 심’ 그 자체는 ‘악’이 아니지만, 타인을 희생하면서까지 그 욕심을 채우려 할 때 우리는 그 걸 ‘탐욕(greed)’이라 고 부른다. 탐욕보다 배려(consideration)를 먼저 기를 수 있는 엔지니어가 많아졌으면 좋겠다”

마지막으로...“Don’t waste -too much- time to choose technology. Instead, turn your pc on and write some code. I swear. That is much more better!”
