Connecting Your Tool to Real Data (Sheets, DBs, APIs)

Quick Summary

Connecting real data turns a prototype into an operational dependency. The design must protect source systems through clear ownership, least privilege, validation, reconciliation, and safe failure behavior.

What you will learn

·Choose between spreadsheet, database, and API data connections
·Define source-of-truth, identifiers, permissions, and data contracts
·Test synchronization, validation, conflicts, failures, and reconciliation
