Course Overview
Continuing on from COMP 1630 , this hands-on course is aimed at students who already understand relational database, data modeling, and the importance of improving Data Quality (DQ). COMP 3839 starts by exploring the strategic goals and business value of establishing baselines for Data Quality improvement. Key topics include the business impact of data quality, data profiling techniques, Capability and Maturity models, plus Data Quality improvement roadmaps. Stra tegies for securing executive support, Data Contracts and Data Mesh, and Data Observability practices will also be discussed. Labs, exercises, assignments, and a project emphasize how to prioritize, plan, and execute data cleaning efforts, using both traditional techniques and AI tools to assess and enhance data quality. Data Quality supports for Data Engineering and Data Governance approaches will be introduced. Homework assignments and a project focus on how to use DQ techniques with AI to measure data quality. COMP 3839 is a required course in the Applied Database Administration and Design (ADAD) Associate Certificate; the Applied Data Analytics Certificate (ADAC) and an elective in the Computer Systems Technology (CST FLEX) Diploma. Successful participants learn how to apply a data quality framework to data migration projects and are better prepared to move on to higher-level data modelling, business intelligence and data analytics courses.
