Material Tracking ERD
R
Renso Höllhumer, Solutions ArchitectA detailed entity-relationship model for a material hauling and tracking system. Covers customers, jobs, tickets, materials, haulers, and billing — with all foreign key relationships and field-level detail. A solid starting point for teams building dispatch, logistics, or field service software who need to define their data model before writing schema migrations.
How to create a Material Tracking ER Diagram
To create a material tracking ER diagram, follow these steps:
01.
Start with the AI agent
Describe your system in plain language: "I need an ERD for a material hauling system with customers, jobs, tickets, and haulers." Let AI generate a first draft, then iterate.
02.
Define your primary entities
Identify the core tables: CUSTOMER, JOB, TICKET, MATERIAL, HAULER, INVOICE.
03.
Add field-level detail
For each entity, specify data types and PK/FK annotations. Example: int id PK, string companyName, boolean isResidential.
04.
Define relationships with cardinality
Use ||--o{ for one-to-many and ||--|| for one-to-one. Label each relationship with a short verb phrase in quotes.
05.
Build iteratively
Start with two entities and the relationship between them. Add one entity at a time and verify the diagram renders before continuing.
06.
Use AI to catch missing fields
After your first draft, prompt: "What fields am I likely missing for a real-world hauling system?" It will surface things like coiRequired, taxExemptionCategory, and billing contacts.
