This course aims to introduce the student to core concepts and practical skills for engineering the data in Web-service-oriented data-driven applications. Specifically, the course aims to expose students to basic infrastructure for building data services on the Web, including techniques to access and ingest data in internal/external sources, develop software services to curate (e.g. extract, transform, correct, aggregate the data), develop services to apply various analytics and develop services to visualize the data to communicate effectively using data. The course uses the Python programming language as the practical basis for its modules. However, the concepts taught are universal and can be applied to any other web development language/framework.
