Data accuracy is generally expressed as a confidence interval (CI). For most credible studies the confidence interval is set at no less than 95 percent. This (if i remember correctly) means that 95 percent or more of the information collected can be trusted as valid and free of confounding variables.

How can you check the accuracy of your data?
No
How do related tables improve the accuracy of a data in a database?
In short, they do not. Relating tables in a database defines the relationships between the data sets in the different tables and allows the data to be accessed more efficiently, but it does not affect the accuracy of the data entered.
How do you write in a suitable degree of accuracy 1.079871565?
First you must decide what is a "suitable degree of accuracy" for a particular problem. In many cases, 4 or 5 significant digits are appropriate, or even 3. But it depends a lot on the original data (the final result is not supposed to look more accurate than the accuracy you can justify from the original data), and the purpose of the data (in some cases you need a higher accuracy than in others).
