1. Understanding Data Integrity and Accuracy
Data integrity refers to the accuracy, consistency, and trustworthiness of your data. Ensuring data integrity means that the data is always correct and consistent, and that it can be trusted for decision-making purposes. On the other hand, data accuracy focuses on the precision of the data, ensuring that the data reflects the true state of the world it represents.
In the real world, a lack of data integrity and accuracy can lead to significant problems.

Another key aspect of the course is learning how to implement data validation rules. These are rules that determine what valid data looks like, ensuring that only accurate and relevant data is stored in your systems.
