Tables are the basic building blocks of a relational database.
Definition: The domain of a database attribute is the set of all allowable values that attribute may assume.Examples: A field for gender may have the domain {male, female, unknown} where those three values are the only permitted entries in that column.
They just are

A condition.
Logical operators don't Compare values they combine Boolean values and produce a Boolean result. Examples of logical operators are && (and), , (or), ! (not). If you have two Boolean values and you combined them with the && operator the result will be (TRUE) only if both values were (TRUE). Relational operators compare two values and produce a Boolean result. Most of the time we use logical operators to combine the results of two or more comparison expressions that use relational operators.

It could be an equation or an expression or a condition.
Relational tuple calculus has its variables range over tuples, where domain relational calculus ranges its variables over the field values, or domain elements. Both types of calculus are subsets of first order logic.

Relational stress refers to tension, conflicts, or difficulties that arise within relationships with others, such as with family members, friends, or colleagues. It can be caused by communication problems, differences in values or beliefs, misunderstandings, or unmet expectations. Relational stress can negatively impact mental and emotional well-being if not addressed.
Repetition of Information is a condition in a relational database where the values of one attribute are determined by the values of another attribute in the same relation, and both values are repeated throughout the relation. This is a bad relational database design because it increases the storage required for the relation and it makes updating the relation more difficult. - Inability to represent information is a condition where a relationship exists among only a proper subset of the attributes in a relation. This is bad relational database design because all the unrelated attributes must be filled with null values otherwise a tuple without the unrelated information cannot be inserted into the relation.

It is the number of the attribute in the relation
No, the properties inside the distortion would be consistent with universal values however the inter-relational values in the area of transition might be skewed.
Sounds like a Boolean expression: I'm outside AND getting wet > it's raining.
