## Penjelasan Relasi
|
||||
|
||||
1. **Customers** (1) -- (0..*) **Service Requests**
|
||||
- Satu pelanggan (customer) dapat memiliki banyak permintaan layanan (service requests).
|
||||
|
||||
2. **Service Requests** (1) -- (0..*) **Request Parameters**
|
||||
- Satu permintaan layanan dapat meminta banyak parameter untuk diuji.
|
||||
|
||||
3. **Analysis Parameters** (1) -- (0..*) **Request Parameters**
|
||||
- Satu parameter analisis dapat diminta dalam banyak permintaan layanan.
|
||||
|
||||
4. **Sample Types** (1) -- (0..*) **Analysis Parameters**
|
||||
- Satu jenis sampel dapat memiliki banyak parameter analisis.
|
||||
|
||||
5. **Service Requests** (1) -- (0..*) **Sampling Plans**
|
||||
- Satu permintaan layanan dapat memiliki banyak rencana sampling.
|
||||
|
||||
6. **Sampling Plans** (1) -- (0..*) **Samples**
|
||||
- Satu rencana sampling dapat menghasilkan banyak sampel.
|
||||
|
||||
7. **Service Requests** (1) -- (0..*) **Samples**
|
||||
- Satu permintaan layanan dapat memiliki banyak sampel.
|
||||
|
||||
8. **Sample Types** (1) -- (0..*) **Samples**
|
||||
- Satu jenis sampel dapat memiliki banyak sampel.
|
||||
|
||||
9. **Samples** (1) -- (0..*) **Analysis Results**
|
||||
- Satu sampel dapat memiliki banyak hasil analisis.
|
||||
|
||||
10. **Analysis Parameters** (1) -- (0..*) **Analysis Results**
|
||||
- Satu parameter analisis dapat digunakan untuk banyak hasil analisis.
|
||||
|
||||
11. **Service Requests** (1) -- (0..*) **Reports**
|
||||
- Satu permintaan layanan dapat menghasilkan banyak laporan.
|
||||
|
||||
12. **Users** (1) -- (0..*) **Activity Logs**
|
||||

|
||||
|
||||
13. **Users** berhubungan dengan banyak tabel lain melalui kolom seperti:
|
||||
- admin_id pada Service Requests
|
||||
- sampling_officer_id pada Sampling Plans
|
||||
- sampling_officer_id pada Samples
|
||||
- received_by pada Samples
|
||||
- analyst_id pada Analysis Results
|
||||
- verified_by pada Analysis Results
|
||||
- prepared_by, verified_by, approved_by pada Reports

## Cara Menggunakan Diagram Mermaid
|
||||
|
||||
Diagram Mermaid ini dapat divisualisasikan dengan beberapa cara:
|
||||
|
||||
1. **GitHub**: GitHub secara native mendukung rendering diagram Mermaid dalam file Markdown.
|
||||
|
||||
2. **Mermaid Live Editor**: Kunjungi [Mermaid Live Editor](https://mermaid.live/) dan paste kode Mermaid di atas untuk melihat dan mengedit diagram secara interaktif.
|
||||
|
||||
3. **Plugin VS Code**: Gunakan plugin Mermaid untuk Visual Studio Code untuk melihat diagram secara langsung saat mengedit.
|
||||
|
||||
4. **Website Dengan Mermaid.js**: Tambahkan script Mermaid.js ke website Anda:
|
||||
```html
|
||||
<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
|
||||
<script>mermaid.initialize({startOnLoad:true});</script>
|
||||
```
|
||||
|
||||
5. **Export ke Image**: Gunakan Mermaid Live Editor untuk mengekspor diagram ke format PNG, SVG, atau PDF.
