About This Architecture

Labkesda Sample Testing System ER diagram models a complete laboratory testing lifecycle from client intake through sample registration, testing, QC verification, and final reporting. The schema connects User and Role entities for access control to core workflows: PermohonanPengujian (test requests) link to JadwalSampling and Sampel (samples), which flow through RegistrasiSampel, LabelSampel, and FormSampling for intake and tracking. HasilUji (test results) and VerifikasiQC (quality control verification) ensure data integrity before LaporanHasilUji (final reports) are generated and archived. This architecture demonstrates best practices for regulated laboratory operations: audit trails via LogAktivitas, payment tracking through Pembayaran, and document retention via Arsip. Fork and customize this diagram on Diagrams.so to adapt the schema for your laboratory's specific testing parameters, accreditation requirements, or regional compliance standards. The design supports multi-user workflows with role-based access and comprehensive sample chain-of-custody documentation.

What database schema structure supports a complete laboratory testing workflow from sample request through final report?

The Labkesda ER diagram provides a normalized schema with 15+ entities managing the full testing lifecycle: PermohonanPengujian initiates requests, Sampel and RegistrasiSampel track samples, HasilUji and VerifikasiQC handle testing and QC, and LaporanHasilUji generates final reports with Arsip for retention. This design ensures audit trails, role-based access control, and regulatory compliance for
