What is the difference between not null and null?
In database terminology, "not null" means that a column in a table must have a value, and it cannot be empty or null. On the other hand, "null" means that a column can have a missing or unknown value, and it is not required to have a value. In other words, "not null" enforces the presence of a value, while "null" allows for the absence of a value. **
Are there uncountable null sets?
Yes, there are uncountable null sets. A null set is a set with zero measure, meaning it has no size or content. There are uncountably many null sets in the real numbers, such as the Cantor set, which has the same cardinality as the real numbers and is a null set. Therefore, there are uncountable null sets in mathematics. **
