Quality, Accuracy, Completeness, and Timeliness
Perhaps the most significant issue associated with data is the quality of the data. Data quality often boils down to trust. Do I trust that the external data provider is taking the same steps I would take to ensure that data is truthful and reliable? As the amount of data available increases, the issue of data quality becomes more prominent. The more data we use, the more risk of data quality issues. As you view this video, reflect on what you can do to ensure that the quality of the data you use in your business intelligence systems remains high. Pay attention to the concept of data governance. We will look at this in more detail later in the course.
