Model the data
Choose the data model, relationship types and field types for a scenario, and plan imports and exports.






























Platform App Builder is a Developer exam for people who build custom apps without code, with 6–12 months of experience. It covers the data model, formulas, flows and the interface, and asks where declarative tools run out. It has no prerequisite and is one of the four exams behind Application Architect; its guide matches the SU ’26 release.
Choose the data model, relationship types and field types for a scenario, and plan imports and exports.
Use formulas, roll-up summaries, validation rules and Flow Builder, including approvals, and troubleshoot flows.
Customize actions, buttons, layouts and Lightning components so the app fits the way people work.
Manage the app lifecycle with sandboxes, change sets and packages, and choose a deployment plan.
We design this course ourselves. Salesforce runs the exam and issues the credential, and LUNARTECH is independent of Salesforce.
App builders succeed by knowing where clicks end. You learn how the platform’s declarative tools fit together, what they cannot do, and how to extend an org with marketplace apps from AgentExchange before reaching for code.
You build A fit review that sorts a set of requirements into declarative, marketplace and code.
Every app needs a clear answer to who may see and change its data. You apply object and field permissions, organization-wide defaults, roles and sharing rules, and test the result from each user’s side.
You build An access design for one app, tested from three user perspectives.
An app is judged by what it shows managers. You build reports from standard and custom report types, group and filter them, and place charts on dashboards that answer real questions.
You build A report set and dashboard for the app’s main business question.
The data model is the foundation, and it is hard to change later. You choose between standard and custom objects, pick relationship types, and select the field type that fits each piece of data.
You build A data model for a business scenario, with each relationship and field type justified.
Data arrives from spreadsheets and other systems, and leaves again for audits and backups. You choose the right import tool, use external IDs to relate records, and export safely.
You build A tested import of related records from spreadsheets, with duplicates handled.
Calculated fields keep data consistent without code. You write formulas for text, numbers, dates and logic, build roll-up summaries across master-detail relationships, and avoid the limits that make formulas break.
You build A set of formula and roll-up fields that calculate a score and a total for an app.
Bad data costs more to fix than to prevent. You write validation rules that catch errors at save, give users clear messages, and let administrators bypass them safely during loads.
You build A validation rule set with clear messages and a safe bypass.
Flow is the main automation tool of the platform. You build record-triggered, screen, scheduled and autolaunched flows, work with variables, loops and decisions, and choose the right flow type for each process.
You build Three flows of different types that automate one business process.
Some processes need a person to decide, and every flow eventually misbehaves. You build approvals, use debug and run history to troubleshoot flows, and see where Agentforce can take over steps from a flow.
You build An approval flow with a documented debugging of one fault.
People work through what they see on a record. You customize actions, buttons and links, set up page layouts and compact layouts per role, and keep screens short enough to be used.
You build Role-specific layouts and actions for one object.
Lightning App Builder lets you shape pages without code. You build record, app and home pages, use dynamic forms and visibility rules, add components, and check how the app looks on mobile.
You build A Lightning app with record pages, visibility rules and mobile checks.
An app must travel from build to production without breaking anything. You choose a sandbox type, move changes with change sets or packages, and plan a deployment with testing and rollback in mind.
You build A deployment plan that moves an app from sandbox to production.
Build one complete app from a business story: data model, access, automation, interface, reports and deployment. You choose each tool on purpose and explain where you stopped using clicks.
You build A complete no-code app with data model, flows, interface, reports and a deployment plan.
