It is an administrative process that incorporates acquiring, validating, storing, protecting and processing the data.

Data management ensures the accessibility, reliability, and timeliness of the data to the users.

Explanation of Solution

Experience in data quality and data management:

“Yes”, one can have an experience in data quality and management.

Reasons:

The use of data management leads to high-quality of data.

Improved data quality results in decision-making across an organization.

Good data decreases risk and it results in consistent improvement.

Explanation of Solution

Data quality problem:

“Yes”, one might encountered the data quality problem.

Reasons:

It may due to manual data entry errors. Humans can make errors and even small data set manually entered by humans likely to contain errors.

Lack of complete information leads to data quality problem.

In some cases, one can find data ambiguity, which leads to data quality problems.

Explanation of Solution

Solving data quality problem:

The common data quality problem issues it that missing information.

To solve this issues, one might understand the reason behind why the values are missing.

The next step is to track the data lineage of the data source to identify the systemic issues during data capture.

Knowing the source of missing value will often reduce to solve the problem.
