CS3492 DATABASE MANAGEMENT SYSTEMS

L T P C: 3 0 0 3

COURSE OBJECTIVES:

• To learn the fundamentals of data models, relational algebra and SQL
• To represent a database system using ER diagrams and to learn normalization techniques
• To understand the fundamental concepts of transaction, concurrency and recovery processing
• To understand the internal storage structures using different file and indexing techniques which will help in physical DB design
• To have an introductory knowledge about the Distributed databases, NOSQL and database security

UNIT I RELATIONAL DATABASES

Purpose of Database System - Views of data - Data Models - Database System Architecture - Introduction to relational databases - Relational Model - Keys - Relational Algebra - SQL fundamentals - Advanced SQL features - Embedded SQL- Dynamic SQL

UNIT V ADVANCED TOPICS

Distributed Databases: Architecture, Data Storage, Transaction Processing, Query processing and optimization - NOSQL Databases: Introduction - CAP Theorem - Document Based systems - Key value Stores - Column Based Systems - Graph Databases. Database Security: Security issues - Access control based on privileges - Role Based access control - SQL Injection - Statistical Database security - Flow control - Encryption and Public Key infrastructures - Challenges

COURSE OUTCOMES:

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

• CO1: Construct SQL Queries using relational algebra
• CO2: Design database using ER model and normalize the database
• CO3: Construct queries to handle transaction processing and maintain consistency of the database
• CO4: Compare and contrast various indexing strategies and apply the knowledge to tune the performance of the database
• CO5: Appraise how advanced databases differ from Relational Databases and find a suitable database for the given requirement.
