Data Integration Tools Aren't the Problem. Your Source Data Is.
Data integration tools are designed to move and join data. But what they’re not designed to do is burn half their capacity cleaning up what arrives at the input. When a source exposes a schema built for application performance rather than analytics, the pipeline must compensate: Anything typed as a string because it was easier at build time gets cast into numbers or dates before a calculation can touch it. The difficult truth is this is cleanup and not value-added integration work.
