7. 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

11. Database Intro: What Function Characteristics
Store 저장 / Retrieve 검색 / View 검토 data efficiently & effectively.
Characteristics
A collection of organized data related to a particular subject/purpose
Structured data 구조적 데이터, Security 보안, Control 통제
DataBase Management System (DBMS)
(Data) Storage 저장, Processing 처리/가공, Retrieval 검색
User Interface
Data Entry 데이터 입력, Search 입력, View/Report 검토/보고
Database Design

12. Database: Definitions
Collection of related data 관련된 데이터 and its metadata organized in a structured format 구조적 형식
for optimized information management 정보 관리
Database Management System (DBMS) 
Software that enables easy creation 구축, modification 변경, & access 접속 of databases
for efficient and effective database management 데이터베이스 관리
Database System 
Integrated system 통합 시스템 of hardware, software, data, procedures, & people
that define 결정 and regulate 규제 the collection, storage, management, & use of data within a database environment 데이터베이스 환경
End user data – raw facts of interests to the end user
Metadata – description of data characteristics and relationships
Organization of data helps:
improve data accuracy
improve timely access
correlation and comparison
DBMS: a collection of programs that manages the database structure, control access to data
- Makes data management more efficient and effective
- Query language allows quick answers to ad hoc queries
- Provides better access to more and better-managed data
- Promotes integrated view of organization’s operations
- Reduces the probability of inconsistent data
