DSCI 513: Databases and Data Retrieval

How to work with data stored in relational database systems or in formats utilizing markup languages. Storage structures and schemas, data relationships, and ways to query and aggregate such data.

Course Learning Objectives

By the end of the course, students are expected to be able to:

  1. Use an Entity-Relationship (ER) Diagram to determine the entities, relationships, attributes, data types, primary keys, foreign keys, etc., for a given database application; translate an ER Diagram to a relational database schema.
  2. Write SQL statements to define, query, and update tables in a database.
  3. Write programs containing embedded SQL statements to communicate with and query a database, thereby generating reports requiring more complicated logic and calculations than what is possible via stand-alone SQL.
  4. Write well-formed XML; use XPath and XQuery to write simple queries over an XML repository (i.e., XML database).
  5. Explain basic concepts of the Map Reduce paradigm.
