Data Quality and Management
This chapter is all about making sure that you have high-quality data that is easy to access and use. Instead of focusing on policies, such as data governance, these are standards and techniques used to make sure that you have the best data possible because inaccurate data can only produce inaccurate results. First, we will go over what quality control is, when you should use it, and what sorts of things it is checking. Next, we will talk about specific methods for quality control. Finally, we will cover the concept of master data management and when to apply it.
In this chapter, we’re going to cover the following main topics:
- Understanding quality control
- Validating quality
- Understanding master data management
