• 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

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.
