11relation

11relation is a concept in mathematics and computer science that refers to the relationship between two sets of data points, where each data point in one set is associated with exactly one data point in the other set. This relationship is often represented as a function or a mapping, where each element from the domain (the first set) is paired with a unique element from the codomain (the second set). In the context of databases, an 11relation is a type of relationship between two tables, where each record in one table is associated with exactly one record in the other table. This is typically achieved through the use of a foreign key, which is a field in one table that uniquely identifies a record in another table. The 11relation is a fundamental concept in various fields, including data modeling, database design, and functional programming. It ensures data integrity and consistency by enforcing a one-to-one correspondence between data points.
