Components of a Database System
- Hardware: computer, storage devices
- Software: database management system (DBMS), operating system
- Data: actual data stored in the database
- People: database administrator, users
- Procedures: instructions for using the database system
Database Design Considerations
- Data integrity: ensuring data accuracy and consistency
- Data security: protecting data from unauthorized access
- Data scalability: designing for large amounts of data
- Data performance: optimizing database speed and efficiency
Storage of Small Databases
- Small databases are typically stored on hard disks, solid-state drives, or other storage devices
Dominant Database Models of the 1980s
- Relational database management systems (RDBMS)
- Object-oriented database management systems (OODBMS)
- Object-relational database management systems (ORDBMS)
