                    Database Management Systems 
Massive - terabytes
Persistent
Safety
Multi-user: Concurrency Control
Convenience: Physical Data Independence, High-Level query language
Efficiency
Reliability
 
 
Database applications may be programmed via “frameworks”(Django, Ruby on rails, …)
DBMS run in conjunction with “middleware”(web server…)
Data intensive applications may not use DBMS at all(data stored in files: Hadoop)
 
 
Key Concept 
Data Model: Relational, XML, Graph…
Schema v.s. Data: Types and Variables
Query Language
 
 
Key People 
DBMS implementer: Build systems
Database designer: Establish schema
