Study Notes
DBMS Architecture & Database Modeling
- A DBMS has several useful features, including:
- Isolation of programs and data (Program – data independence)
- Support of multiple user views
- Use of a catalog to store the DB Schema
Three-Schema Architecture
- Also known as ANSI/SPARC architecture
- ANSI: American National Standards Institute
- SPARC: Standards Planning and Requirement Committee
- Goal: separate user applications from the physical database
- Achieves and visualizes:
- Use of a catalog to store the database description (schema) to make it self-describing
- Insulation of programs and data (program-data and program-operation independence)
Note: I've removed the redundant parts and reorganized the text to make it more concise and easy to read.
