Why Zero is Often the Wrong Default Value Setting in Microsoft Access. Fitness #66

In this video, we'll talk about why using zero as a default value when designing tables in Microsoft Access can often lead to bad data and misleading results, and why it's better to use null values. We'll also cover where the fitness database series is headed, focusing on tracking body composition, the basics of building new tables from scratch, choosing fields and data types, atomic data structure, and organizing your data for more useful charts and queries. Even if you aren't interested in fitness, the techniques shown can be applied to any Microsoft Access database project.
