Title: Stars, Dimensions, and Stories
In this session, we will focus on two critical phases of the data analytics pipeline. In the pre-analysis phase, how do we best store data for efficient retrieval, slicing, and dicing (star schema and dimensional modeling)? In the post-analysis phase, how do we best present insights to inform decision making (visualization and storytelling)?
A relational model, also referred to as a 3NF model, is aimed at reducing data redundancy and repetition. It is optimized for the addition, updating, and deletion of data in a real-time transactional system. In this talk, however, we will explore why the standard normalization approach to data modeling is not the best fit for modern-day big data analytics. Dimensional model, in contrast, favors highly denormalized data with flattened many-to-one relationships and is optimized for the retrieval, summarization, and analysis of information.
In the second part of the session, we will focus on visualization and storytelling and their direct influence on decision making. Success in this space is determined by the ability to understand the audience and its needs, knowledge of the art and science of visual perception, and masterful editing. We will go over the skills that enable effective technical storytelling.
