What is Data quality?

Data quality refers to the overall level of excellence and trustworthiness of data.

Importance of Data Quality:

Data quality is important because it affects the accuracy and usefulness of the information that is derived from it. Poor quality data can lead to incorrect conclusions, bad decision-making, and wasted resources. For example, a business might make a poor decision because the data it was using was inaccurate or incomplete. Or, a research study might produce inaccurate results because the data it was based on was of poor quality.

Moreover, it also plays an important role in the efficiency and effectiveness of any organization. Data is the fuel that runs today's digital economy, and poor-quality data can slow down or even bring operations to a standstill. With high-quality data, companies can more easily automate processes, make better decisions, and create new revenue streams. 

In summary, data quality is important because it affects the accuracy and usefulness of the information that is derived from it, can be a legal and regulatory compliance matter, and can also impact the efficiency and effectiveness of the organization.

Deciding between a database and a data warehouse largely depends on the specific needs of your organization and the type of data you're working with. Some of the factors for consideration are: Ø  Data Volume : When you have large volume of data (e.g., terabytes or more), then better to go for a data warehouse as data warehouses are optimized for handling large amounts of data.
