What is the impedance mismatch problem?

The impedance mismatch problem refers to the difficulties that arise when integrating different systems or technologies that have incompatible data models or structures. This is commonly seen in the context of relational databases and object-oriented programming, where the differences in how data is represented can lead to inefficiencies and complexities in data handling. It can also occur between different software components, making it challenging to exchange information seamlessly. Addressing this issue often involves using middleware or mapping techniques to bridge the gap between disparate systems.
