Genealogy Research App Backend Template
FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote tracking
A production-ready genealogy research backend on Back4app for FamilyTree records, FamilyNode relatives, DocumentScan sources, DnaMatchLog reviews, and ResearchNote findings. Includes ER diagram, field guide, JSON schema, API sandbox, and an AI Agent prompt for rapid bootstrap.
Genealogy Research Takeaways
This template gives you a genealogy research backend with FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote so your team can organize lineage evidence and source trails.
- FamilyTree dashboarding — Model each FamilyTree with treeName, originRegion, status, and owner so every lineage workspace stays traceable.
- FamilyNode lineage tracking — Record each FamilyNode with fullName, relationship, birthDate, deathDate, sourceStatus, and createdBy for clear review.
- DocumentScan source catalog — Store each DocumentScan with title, fileUrl, documentType, recordDate, and uploadedBy for source-backed evidence.
- DnaMatchLog review flow — Track each DnaMatchLog with kitId, matchName, sharedCm, matchStatus, and reviewedBy for DNA follow-up.
- ResearchNote evidence notes — Link each ResearchNote to a FamilyTree and optional relatedNode so findings stay attached to the right branch.
Overview: Genealogy Research App
A healthy genealogy research pipeline has clear stages, owners, and exit criteria — otherwise “in progress” becomes a black hole. Customers feel it in the ETA you promise. Back4app anchors FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote for genealogy research practices that need deadlines, documents, and comms in one permissioned workspace. The schema covers User (username, email, role), FamilyTree (treeName, originRegion, status, owner), FamilyNode (fullName, relationship, birthDate, deathDate, sourceStatus, createdBy), DocumentScan (title, fileUrl, documentType, recordDate, uploadedBy), DnaMatchLog (kitId, matchName, sharedCm, matchStatus, reviewedBy), and ResearchNote (subject, body, relatedNode, author). Connect your preferred frontend and start capturing family history with structured lineage and source links.

What you get in the Genealogy Research template
If genealogy research stakeholders cannot answer simple questions in seconds, they will answer them in meetings — slowly and expensively.
The hub highlights FamilyTree, FamilyNode, and DocumentScan so you can compare client stacks against the same entities, fields, and relationships.
Genealogy App Feature Set
Every technology card in this hub uses the same genealogy schema with User, FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote.
User accounts and roles
User stores username, email, password, and role.
FamilyTree and FamilyNode records
FamilyTree keeps treeName, originRegion, status, and owner, while FamilyNode keeps fullName and relationship.
DocumentScan source registry
DocumentScan captures title, fileUrl, documentType, and recordDate.
DnaMatchLog reviews
DnaMatchLog stores kitId, matchName, sharedCm, and matchStatus.
Why Build Your Genealogy Research Backend with Back4app?
Back4app gives you FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote primitives so your team can focus on evidence review instead of database plumbing.
- •FamilyTree and FamilyNode structure: FamilyTree and FamilyNode classes store treeName, originRegion, fullName, relationship, and sourceStatus in a queryable format.
- •DocumentScan and source control: DocumentScan records keep title, fileUrl, documentType, recordDate, and uploadedBy together so each source stays attached to the right tree.
- •DNA review and note trails: DnaMatchLog and ResearchNote records keep kitId, matchName, sharedCm, matchStatus, subject, and relatedNode so reviewers can follow each comparison.
Build and iterate on genealogy workflows quickly with one backend contract across all platforms.
Genealogy Research Benefits
A genealogy research backend that helps you keep source trails and lineage notes organized.
Faster research setup
Start from a complete User, FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote schema rather than defining it from zero.
Source-linked family records
Tie each FamilyNode to sourceStatus, birthDate, deathDate, and createdBy for clearer attribution.
Scan and note traceability
Use DocumentScan fields like title, fileUrl, documentType, and recordDate, then connect ResearchNote entries to the right FamilyNode.
DNA review traceability
Use DnaMatchLog fields like kitId, matchName, sharedCm, and matchStatus to document follow-up work.
Controlled access to sensitive lineage notes
Use ACL and CLP so only authorized users can edit FamilyTree, FamilyNode, DocumentScan, and ResearchNote entries.
Chronological evidence storage
Store createdAt, updatedAt, recordDate, and reviewedBy across classes without flattening the research trail.

7 fields in User
Role Permissions and Access
How ACL and CLP strategy secures users, family trees, family nodes, scans, DNA logs, and research notes.
Staff login protection
Use the User class for authenticated staff only, with role values such as researcher, reviewer, and admin.
Source integrity for tree records
Use Cloud Code validation so FamilyTree, FamilyNode, and ResearchNote entries include the expected treeName, fullName, sourceStatus, or body before save.
Scoped lineage visibility
Limit reads so research teams can view only the FamilyTree branches, DocumentScan files, and DnaMatchLog entries they are authorized to review.

Raw JSON schema definition ready to copy into Back4app or use as implementation reference.

}Build with AI Agent
Use the Back4app AI Agent to generate a real genealogy research app from this template, including frontend, backend, auth, and FamilyTree, FamilyNode, DocumentScan, DnaMatchLog, and ResearchNote flows.
Create a genealogy research app backend on Back4app with this exact schema and behavior. Schema: 1. User (use Back4app built-in auth profile): username (String, required), email (String, required), password (String, required), role (String, required); objectId, createdAt, updatedAt (system). 2. FamilyTree: treeName (String, required), originRegion (String, optional), status (String, required), owner (Pointer to User, required); objectId, createdAt, updatedAt (system). 3. FamilyNode: tree (Pointer to FamilyTree, required), fullName (String, required), relationship (String, required), birthDate (Date, optional), deathDate (Date, optional), sourceStatus (String, required), createdBy (Pointer to User, required); objectId, createdAt, updatedAt (system). 4. DocumentScan: tree (Pointer to FamilyTree, required), title (String, required), fileUrl (String, required), documentType (String, required), recordDate (Date, optional), uploadedBy (Pointer to User, required); objectId, createdAt, updatedAt (system). 5. DnaMatchLog: tree (Pointer to FamilyTree, required), kitId (String, required), matchName (String, required), sharedCm (Number, required), matchStatus (String, required), reviewedBy (Pointer to User, optional); objectId, createdAt, updatedAt (system). 6. ResearchNote: tree (Pointer to FamilyTree, required), subject (String, required), body (String, required), relatedNode (Pointer to FamilyNode, optional), author (Pointer to User, required); objectId, createdAt, updatedAt (system). Security: - Only authenticated users can create tree nodes, scans, notes, and DNA logs. - Tree owners and reviewers can update tree content; restrict document scans to their uploader or an admin role. - Protect PII and family history notes with role-based ACLs and class permissions. Auth: - Sign-up, login, logout. Behavior: - Manage family trees, add person nodes, attach document scans, review DNA matches, and write research notes. Deliver: - Back4app app with schema, ACLs, CLPs; frontend for family trees, document scans, DNA match logs, and note review.
