In object oriented programming, there is one problem called Impedance Mismatch. The problem occurs when there is a mismatch / differences / gap between objects in an application and representation of data in storage.
Some differences that can cause Impedance Mismatch are:
- Data type
- Structural and integrity
Features in programming language and framework can help reduce Impedance Mismatch, such as LINQ and Entity Framework in .Net framework.
