Заметки
GetRelationCount is useful if you need to loop through all defined relations in the database's Relations collection. To obtain information about a given relation in the collection, see GetRelationInfo.
To illustrate the concept of a relation, consider a Suppliers table and a Products table, which might have a one-to-many relationship. In this relationship, one supplier can supply more than one product. Other relations are one-to-one and many-to-many.
