The Data Architecture Designer certification is about designing data on Salesforce that stays fast, accurate and trustworthy as it grows. Questions are scenarios: a company with millions of records, several source systems and a performance problem, and you have to choose the design that fixes it.
What to learn
Data modeling
Choosing standard or custom objects, relationship types and their effect on sharing and performance, and when data belongs outside Salesforce entirely, in big objects or external objects.
Large data volumes
What slows orgs down at scale: queries that are not selective, too many child records under one parent, and too many records owned by one user. Learn data skew in its common forms (account, ownership and lookup skew), how indexes and selective filters help, and why archiving old data is often the real fix.
Data migration
Loading data in the right order so relationships resolve, using external IDs to match records, the Bulk API for large loads, and turning off automation that would slow a load or fire on historical data.
Integration and data
Master data management: deciding which system owns each piece of data, building a single trusted record from several sources, and keeping systems in sync.
Governance
Data quality rules, ownership, retention, field history, and meeting privacy obligations for personal data.
How to study it
- Start from the problem. For each scenario, name the symptom first (slow reports, record locks, duplicates) before choosing a feature.
- Learn the limits. Many answers depend on knowing when a design stops working as data grows.
- Draw it. Sketch the data model and the flow between systems; architecture questions are easier on paper.
