Glossary / Evaluation and implementation guide

Schema

A schema is the formal definition of a data structure: which fields exist, their types, and which are required.

In automation platforms, schemas govern what a workflow can accept, transform, and pass downstream, so mismatches between your CRM or warehouse schema and the platform's model cause silent failures or dropped fields.

A practical example

Example: your lead object requires phone_number as a string with country code, but the platform's schema expects phone as an integer, so every sync drops the value until the mapping is corrected.

What to evaluate before investing

  • Ask how the platform handles unknown or extra fields when your source schema changes
  • Test whether you can define custom field types and required-field rules without vendor support
  • Request documentation on schema versioning and what happens to running workflows after an update

Limitations and tradeoffs

Rigid schemas protect data quality but make every upstream change an integration project; schemaless flexibility trades that safety for harder debugging.
