이 책의 시작은 10여 년 전으로 거슬러 올라간다. Oracle의 Library Cache에 대한 깊은 이해는 현장에서 금융시스템을 운영하고 튜닝하는 DBA로서 필수적임에도 불구하고 그동안 Oracle에 관련된 어떠한 책에서도 명쾌하게 설명하지 않았다. OWI event를 중심으로 Library Cache에 아키텍처를 추론하여 짐작하였을 뿐, 명확하게 구조적으로 설명된 자료는 없었다. 명확한 구조를 모른다는 것은 정확한 솔루션을 제시하지 못한다는 것이다. 국내의 서적 뿐만 아니라 해외의 유명한 구루들의 서적에서도 마찬가지였다. 예를 들면, enq lock은 holder session과 waiter session 단 2개로 locking 상황을 재현하면서 비교적 명쾌하게 설명이 가능했으나 Library Cache에서는 수많은 세션을 동시에 실행시켜서 부하 테스트 방법으로 비슷한 상황을 재현할 수 있을 뿐 enq처럼 명확하게 설명되지 못했다. 현장의 많은 DBA들은 정확한 이유도 모른 체 flush 명령을 내리거나, 세션을 kill 시키고 sql의 hard parsing을 줄이기 위한 bind variable을 쓸 뿐 정확한 메커니즘에 대한 이해가 부족했다. 필자 역시 후배와 수많은 Library Cache 덤프를 떠보고 국내외 유명 서적을 탐독했으나 그 내부구조에 대한 원리를 명확히 이해할 수 없어서 답답하기만 하였다. 그런 답답함이 이번 연구를 통하여 많이 해소되었다. Oracle 내부를 탐험하며 구석구석 사진을 찍고, 그 동작 원리를 이해하는 것은 하나의 예술작품을 보는 것과 같았다. 그러나 이만큼의 성과가 나올 수 있었던 것은 10여년 전 Library Cache의 정확한 메커니즘을 파헤치기 위해서 저자와 함께 수개월간 Library Cache 덤프를 수천 번 수행하고 분석했었던 기초 자료가 있었기에 가능했고 그 작업을 함께 했었던 이인규 책임에게 감사의 마음을 전하고 싶다. 지난 1권에서는 트랜잭션 처리와 관련된 메커니즘을 세 개의 주요 DBMS를 대상으로 비교 연구하였고, 이번 2권에서는 Buffer Cache를 비롯한 Shared Memory 메커니즘을 비교 연구하였다. 다음 3권에서는 아직 다루지 못했던 PGA를 비롯한 기타 아키텍처를 추가적으로 연구하고 그동안 연구해온 깊은 아키텍처의 이해를 바탕으로 현장에서 발생하는 다양한 성능저하 케이스, 에러 케이스 등의 원리를 명확하게 연구해 보려고 한다. 또한 앞서 말했던 하둡을 비롯한 최근의 다양한 데이터 저장플랫폼과 그동안 연구했던 RDBMS와의 비교연구 또한 계속 이어질 것이다.

“주요 DBMS 내부 동작원리에 대한 심층 비교연구” 저자들은 빅데이터 시대의 새로운 데이터 플랫폼을 모색하기 위한 첫 번째 여정으로 기존의 주요 RDBMS인 Oracle, PostgreSQL, MySQL 이 세 가지 DB를 선택하여 그 내부 동작원리를 심층적으로 비교 규명하고 있다. 이 책에서는 기존의 거의 모든 튜닝 책에서 주로 사용하는 스크립트 테스트 방법론을 벗어나서 저자들의 독자적인 DIA Method 방법론을 사용하여 분석하고 있다. 이 DIA Method는 저자들이 미션 크리티컬 시스템을 구축하고 운영하면서 맞닥뜨렸던 수많은 난제를 해결하기 위해 지난 10여 년 동안 점차적으로 발전시킨 것이다. 또한 DB Catalog와 Formatted Block Dump를 친절하게 제공하지 않는 오픈소스 DBMS인 MySQL과 PostgreSQL의 내부 동작원리를 규명하는데 매우 효과적인 접근 방법이 되어 주었다. 독자들은 이 책을 통하여 각 RDBMS의 내부 동작원리와 그 한계점을 알게 될 것이다.

Architects look at thousands of buildings during their training, and study critiques of those buildings written by masters. In contrast, most software developers only ever get to know a handful of large programs well -- usually programs they wrote themselves -- and never study the great programs of history. As a result, they repeat one another's mistakes rather than building on one another's successes.This second volume of The Architecture of Open Source Applications aims to change that. In it, the authors of twenty-four open source applications explain how their software is structured, and why. What are each program's major components? How do they interact? And what did their builders learn during their development? In answering these questions, the contributors to this book provide unique insights into how they think.

Technological advances and innovative perspectives constantly evolve the notion of what makes up a digital library. Archives and the Digital Library provides an insightful snapshot of the current state of archiving in the digital realm. Respected experts in library and information science present the latest research results and illuminating case studies to provide a comprehensive glimpse at the theory, technological advances, and unique approaches to digital information management as it now stands. The book focuses on digitally reformatted surrogates of non-digital textual and graphic materials from archival collections, exploring the roles archivists can play in broadening the scope of digitization efforts through creatively developing policies, procedures, and tools to effectively manage digital content. Many of the important advances in digitization of materials have little to do with the efforts of archivists. Archives and the Digital Library concentrates specifically on the developments in the world of archives and the digitization of the unique content of information resources archivists deal with on a constant basis. This resource reviews the current issues and challenges, effective user assessment techniques, various digital resources projects, collaboration strategies, and helpful best practices. The book is extensively referenced and includes helpful illustrative figures. Topics in Archives and the Digital Library include: a case study of LSTA-grant funded California Local History Digital Resources Project expanding the scope of traditional archival digitations projects beyond the limits of a single institution a case study of the California Cultures Project the top ten themes in usability issues case studies of usability studies, focus groups, interviews, ethnographic studies, and web log analysis developing a reciprocal partnership with a digital library the technical challenges in harvesting and managing Web archives metadata strategies to provide descriptive, technical, and preservation related information about archived Web sites long-term preservation of digital materials building a trusted digital repository collaboration in developing and supporting the technical and organizational infrastructure for sustainability in both academic and state government the Archivists’ Toolkit software application Archives and the Digital Library is timely, important reading for archivists, librarians, library administrators, library information educators, archival educators, and students.
