Learning Objectives

This course provides an introduction to relational database systems. The topics covered include the relational model, SQL, transactions, database design, and concepts and algorithms for building database management systems.

Learning outcome

Upon successful completion, the students will be able to define program-data independence, data models for database systems, database schema and database instances. He/she will able to recall Relational Algebra concepts, and use it to translate queries to Relational Algebra, identify Structure Query Language statements used in creation and manipulation of database, identify the methodology of conceptual modeling through Entity Relationship model, identify the methodology of logical model and also identify the methodology of physical model. He/she will be able to describe the differences between OODBMS, ORDBMS and RDBMS and describe the practical implications of each approach. Student will also be able to analyze and design a real database application and develop and evaluate a real database application using a database management system.

Syllabus

Introduction - General introduction to database systems; Database - DBMS disctinction, approaches to building a database, data models, database management system, three-schema architecture of a database, challenges in building a DBMS, various components of a DBMS.

E/R Model - Conceptual data modeling - motivation, entities, entity types, various types of attributes, relationships, relationship types, E/R diagram notation, examples. Relational Data Model - Concept of relations, schema-instance distinction, keys, referential integrity and foreign keys, relational algebra operators: selection, projection, cross product, various types of joins, division, example queries, tuple relation calculus, domain relational calculus, converting the database specification in E/R notation to the relational schema.

SQL - Introduction, data definition in SQL, table, key and foreign key definitions, update behaviors. Querying in SQL - basic select-from-where block and its semantics, nested queries - correlated and uncorrelated, notion of aggregation, aggregation functions group by and having clauses, embedded SQL.
