DBMS Goals
•
•
•
•
•
Efficient data management (faster than files)
Large amount of data
High reliability
Information sharing (multiple users)
DBMS Users:
– E-commerce companies, banks, airlines, transportation
companies, corporate databases, government agencies, …
– Anyone you can think of!

Key Database Technologies
• File Management
– provides a file abstraction as a collection of records stored in disk
ICS222
• Index Management and Access Methods
– implements techniques for associative access to data
• Query Optimization and Processing
– given a query and data storage structures, determines an efficient strategy
to evaluate the query.
• Transaction management
– ensures consistency of the database in presence of concurrent transactions
and various types of failures
• Catalog Management
– maintains database schema information
• Authorization and Integrity Management
ICS223
– tests for integrity constraints and user authorization
