Course Syllabus

Abstract

As the amount of data being produced everyday increases, the skill of working with data sources (databases) becomes an essential one for anyone involved in IT or management. After completing the Data Management course students will be able to create a normalized relational database, connect to an existing data source, write complex SQL queries to read and modify the data and prepare business intelligence reports. The course mostly focuses on relational data models, database design and data manipulations with use of programming language. Non-relational databases, physical storage organization and access management are additional topics of the course. The course introduces students to the popular and widely used database server - PostgreSQL.
