Course Requirements Grading Prerequisites Midterm Project (30%) Final Project (70%) Participation (Extra Credit) Prerequisites Basic computer skills Technical background is not required. Database Design

Course Policy This class advocates an open book policy of allowing students to consult textbooks, Internet resources, and classmates when working on assignments to facilitate learning and promote collaboration. The Honor Code is in effect.  With the open book policy, it is especially important to clearly indicate in submitted work any materials used from other sources. Full citation information should be given for such sources. Students are expected to be active participant in class discussions, where they will ask questions, provide insights, and explore ideas.

Introduction to Database

Database Intro: Why & How Data vs. Information Data is a collection of facts. Information is data processed for knowledge. Changing data into information Organize data so that it can be viewed in a useful form. What form will the derived information take? How will information be extracted? What data to collect, how & why? Requirements Identify the Context of data → Metadata Organize 정리, 체계화, 조직화 → Structured Data 구조적 데이터 Summarize 요약 → Information Database Design

Data → Information: 1.Identify Context Obama, Barack H. 19610804 Bush, George H W. 19240612 Bush, George W. 19460706 Clinton, William J. 19460819 Carter, James E. 19241001 Context Living presidents, United States, 2016/1/1 Name (last name, first name middle initial), birthdate (YYYYMMDD) Class Roster, Database Design Course, LIS Department, KNU, Spring 2016 Name (last name, first name middle initial), student ID Database Design
