It is the number of the attribute in the relation
In a database management system (DBMS), an attribute may describe a component of the database, such as a table or a field, or may be used itself as another term for a field. Commonly we can say that an attribute is a "propety" of a database field or its a characteristic or facet of the data field..
It is an attribute that does not occur in some candidate key.

A column in a database represents an attribute to the entity that the table is representing. For example, "hair color" is an attribute if your entity is "customers of a hair salon". This would go in a column of the table (entity) titled "customers" in a management system of a hair salon.
Non-transitive dependency occurs in a database when a relationship between three or more attributes does not imply a direct relationship between all of them. Specifically, if attribute A is dependent on attribute B, and attribute B is dependent on attribute C, it does not necessarily mean that attribute A is dependent on attribute C. This type of dependency can complicate database normalization and design, as it can lead to redundancy and anomalies in data management. Understanding non-transitive dependencies is crucial for ensuring data integrity in relational databases.

A composite attribute in a database is an attribute that can be divided into smaller sub-parts, each representing a distinct property. Instead of storing it as a single value, a composite attribute is broken down into its components to improve data organization and accuracy. This approach helps in reducing redundancy and ensures data integrity within the database.

In database technology, domain refers to the description of an attribute's allowed values. The physical description is a set of values the attribute can have, and the semantic, or logical, description is the meaning of the attribute.
