CS8492 DATABASE MANAGEMENT SYSTEMS NOTES AND MATERIALS 2017 REGULATION

In this post we have posted some notes on CS8492 DATABASE MANAGEMENT SYSTEMS for ANNA UNIVERSITY AFFILIATED COLLEGES STUDENTS.

Here We have listed the the notes whichever we could collect for CS8492 DATABASE MANAGEMENT SYSTEMS subject, We think that it will be helpful for your exam preparation.

OBJECTIVES

To learn the fundamentals of data models and to represent a database system using ER diagrams.
To study SQL and relational database design.
To understand the internal storage structures using different file and indexing techniques which will help in physical DB design.
To understand the fundamental concepts of transaction processing- concurrency control techniques and recovery procedures.
To have an introductory knowledge about the Storage and Query processing Techniques

UNIT I RELATIONAL DATABASES

TOTAL: 45 PERIODS

OUTCOMES:

Upon completion of the course, the students will be able to:

Classify the modern and futuristic database applications based on size and complexity
Map ER model to Relational model to perform database design effectively
Write queries using normalization criteria and optimize queries
Compare and contrast various indexing strategies in different database systems
Appraise how advanced databases differ from traditional databases.
