What do you mean by data design?

Data designing illustrates the types of data that are stored in the system, the relationships between them and the ways that data can be grouped or organised. A data model is that blueprint or roadmap which facilitates a deeper understanding of the stored data.

What is data visualization design?

Data visualization is the act of turning data and numbers into the form of maps, charts, graphs or infographics. This is done because it's easier for the human brain to comprehend information in a visual representation rather than its raw form. Data visualization is a key part of any good data strategy.

What does open by design mean?

Open by design means well considered, systematic and safe release of open data. Open by design equals closed by design, they are two sides of the same coin. In order to safely release data, maintaining public trust, you need to ensure privacy is adequately protected.

Which solid principle helps the use to develop less coupled code?

S-Single Responsibility Principle

This also can be referred to as SRP, it simply means that there should be no more than one reason behind modifying a class i.e. every single class should have one responsibility at the max.
