ok they are used by lines and dots and boxes to help you scientifically.
A controlled experiment can be used to show a cause and effect relationship. ex: an experiment studying the effect of a certain medicine on patients.
No. A table is the primary object used within a database to store data. A typical database will consist of many tables.
In a datamart, data is typically denormalized rather than normalized. This approach is used to optimize query performance and simplify data retrieval for analytical purposes. Denormalization combines data from multiple tables into fewer tables, which can improve read efficiency and speed up reporting. However, the specific design may vary based on the requirements and use cases of the datamart.

to help record your informantion
Data tables are used in controlled experiments to systematically organize and present collected data, making it easier to analyze and interpret results. They provide a clear structure for comparing variables, tracking changes over time, and identifying trends or patterns. By using data tables, researchers can ensure accuracy and consistency in their data reporting, facilitating better communication of findings. Additionally, they serve as a valuable reference for future studies or replication of experiments.

They help to keep good records of measurements and observations.
In the scientific method, data tables and graphs are primarily used during the analysis phase to organize and visually represent the collected data. After conducting the experiment and gathering results, researchers will compile the data into tables for clarity and create graphs to identify trends, patterns, or relationships. This visual representation aids in interpreting the data and drawing conclusions based on the experimental findings. Finally, the results are communicated in the discussion section, where insights and implications are elaborated upon.
who decides how and when data in an organization will be used or controlled
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison
the answer is experiment
gathering data.
You can relate the data present in multiple tables by using the concept of Foreign Keys. for example if we have an employee database that contains various details of an employee scattered in multiple tables, one column in each table can be used to logically group the data in all these tables. For example, the employee number column in each of these tables can be used to relate the data present in these tables.
