The object-relational impedance mismatch is a set of conceptual and technical difficulties that are often encountered when a relational database management system is being used by a program written in an object-oriented programming language or style; particularly when objects or class definitions are mapped in a straightforward way to database tables or relational schemata.

dbpprop:abstract
  • The object-relational impedance mismatch is a set of conceptual and technical difficulties that are often encountered when a relational database management system is being used by a program written in an object-oriented programming language or style; particularly when objects or class definitions are mapped in a straightforward way to database tables or relational schemata. This practice has been recommended and documented by some object-oriented literature as a way to use databases in object-oriented programs. The term object-relational impedance mismatch is derived from the electrical engineering term impedance matching.
  • Als "Object-relational Impedance Mismatch" - oft auch nur Impedance Mismatch - (z. dt. etwa objekt-relationale Unverträglichkeit) bezeichnet man ein Problem der Informatik in der Anwendungsentwicklung, das auftritt, wenn Objekte aus einer objektorientierten Programmiersprache in einer relationalen Datenbank gespeichert werden.
