This enables for relations concerning data for being connected with objects as well as their attributes and never to unique fields.[22] The expression "item–relational impedance mismatch" described the inconvenience of translating between programmed objects and database tables. Object databases and object–relational databases attempt to clear up this problem by furnishing an item-oriented language (occasionally as extensions to SQL) that programmers can use as substitute to purely relational SQL. About the programming aspect, libraries often called object–relational mappings (ORMs) make an effort to solve the same trouble.
