Course Outcomes: The student will be able to :

• Identify, analyze and define database objects, enforce integrity constraints on a database using RDBMS.
• Use Structured Query Language (SQL) for database manipulation.
• Design and build simple database systems
• Develop application to interact with databases.
Full Notes

Question Paper Pattern:

• The question paper will have ten questions.
• Each full Question consisting of 20 marks
• There will be 2 full questions (with a maximum of four sub questions) from each module.
• Each full question will have sub questions covering all the topics under a module.
• The students will have to answer 5 full questions, selecting one full question from each module.
