Consider the following integration scenarios: Moving medical records between EMR systems; financial information between banking systems; HR information between ERP systems; and software development information between SDLC tools.
At first glance the approaches required for these integrations may seem the same. But if you look slightly deeper you will realize that this can’t be the case because of impedance mismatch. I’m defining impedance mismatch as the friction that occurs when trying to align two things or concepts that don’t naturally/actually match. Because many of the hardest impedance mismatches are domain specific, to overcome them you have to have a layer of domain understanding “baked into” your integration software to address business problems.
