# 📊 Design Document vs Actual Implementation

|
## Overview
|
|
|
|
The `backend_structure.txt` is a **DESIGN DOCUMENT** that shows the intended/planned database structure. However, not all tables have been implemented yet.
|
|
|
|

## ⚠️ **Key Discrepancies**
|
|
|
|
### **1. `admin_configurations` vs `system_settings`**
|
|
|
|
**Problem:** I created `admin_configurations` which overlaps with the planned `system_settings`.
|
|
|
|
**Design (`system_settings`):**
|
|
```sql
|
|
system_settings {
|
|
setting_id PK
|
|
setting_key UK
|
|
setting_value
|
|
setting_type
|
|
setting_category
|
|
is_editable
|
|
is_sensitive
|
|
validation_rules
|
|
...
|
|
}
|
|
```
|
|
|
|
**What I Created (`admin_configurations`):**
|
|
```sql
|
|
admin_configurations {
|
|
config_id PK
|
|
config_key UK
|
|
config_value
|
|
value_type
|
|
config_category
|
|
is_editable
|
|
is_sensitive
|
|
validation_rules
|
|
...
|
|
}
|
|
```
|
|
|
|
**Resolution Options:**
|
|
|
|
**Option A:** Rename `admin_configurations` → `system_settings`
|
|
- ✅ Matches design document
|
|
- ✅ Consistent naming
|
|
- ⚠️ Requires migration to rename table
|
|
|
|
**Option B:** Keep `admin_configurations`, skip `system_settings`
|
|
- ✅ No migration needed
|
|
- ✅ Already implemented and working
|
|
- ⚠️ Deviates from design
|
|
|
|
**Option C:** Use both tables
|
|
- ❌ Redundant
|
|
- ❌ Confusing
|
|
- ❌ Not recommended
|
|
|
|
**RECOMMENDATION:** **Option A** - Rename to `system_settings` to match design document.
|
|
|

|
|
|
|
### **2. `tat_alerts` vs `tat_tracking`**
|
|
|
|
**Status:** These serve **DIFFERENT purposes** and should **COEXIST**.
|
|
|
|
**`tat_alerts` (Implemented):**
|
|
- Historical record of TAT alerts sent
|
|
- Stores when 50%, 75%, 100% alerts were sent
|
|
- Immutable records for audit trail
|
|
- Purpose: **Alert History**
|
|
|
|
**`tat_tracking` (Planned, Not Implemented):**
|
|
```sql
|
|
tat_tracking {
|
|
tracking_type "REQUEST or LEVEL"
|
|
tat_status "ON_TRACK to BREACHED"
|
|
elapsed_hours
|
|
remaining_hours
|
|
percentage_used
|
|
threshold_50_breached
|
|
threshold_80_breached
|
|
...
|
|
}
|
|
```
|
|
- Real-time tracking of TAT status
|
|
- Continuously updated as time passes
|
|
- Shows current TAT health
|
|
- Purpose: **Real-time Monitoring**
|
|
|
|
**Resolution:** Both tables should exist.
|
|
|
|
**RECOMMENDATION:** Implement `tat_tracking` table as per design document.
|
|
|
|
---
|
|
|
|
### **3. `holidays` Table**
|
|
|
|
**Status:** **NEW addition** not in original design.
|
|
|
|
**Resolution:** This is fine! It's a feature enhancement that was needed for accurate TAT calculations.
|
|
|
|
**RECOMMENDATION:** Add `holidays` to the design document for future reference.
|
|
|
|

|
|
|
|
## 📋 **Recommended Actions**
|
|
|
|
### **Immediate Actions:**
|
|
|
|
1. **Rename `admin_configurations` to `system_settings`**
|
|
```sql
|
|
ALTER TABLE admin_configurations RENAME TO system_settings;
|
|
ALTER INDEX admin_configurations_pkey RENAME TO system_settings_pkey;
|
|
ALTER INDEX admin_configurations_config_category RENAME TO system_settings_config_category;
|
|
-- etc.
|
|
```
|
|
|
|
2. **Update all references in code:**
|
|
- Model: `AdminConfiguration` → `SystemSetting`
|
|
- Service: `adminConfig` → `systemSettings`
|
|
- Routes: `/admin/configurations` → `/admin/settings`
|
|
- Controller: `admin.controller.ts` → Update variable names
|
|
|
|
3. **Implement `tat_tracking` table** (as per design):
|
|
- Create migration for `tat_tracking`
|
|
- Implement model and service
|
|
- Integrate with TAT calculation system
|
|
- Use for real-time dashboard
|
|
|
|
4. **Update `backend_structure.txt`**:
|
|
- Add `holidays` table to design
|
|
- Update `system_settings` if we made any changes
|
|
- Add `tat_alerts` if not present
|
|
|
|

|
|
|
|
### **Future Implementations (Phase 2):**
|
|
|
|
Based on the design document, these should be implemented next:
|
|
|
|
1. **`notifications` table** - In-app notification system
|
|
2. **`conclusion_remarks` table** - AI-generated conclusions
|
|
3. **`audit_logs` table** - Comprehensive audit trail (currently using `activities`)
|
|
4. **`email_logs` & `sms_logs`** - Communication tracking
|
|
5. **`workflow_templates`** - Template system for common workflows
|
|
6. **`report_cache`** - Performance optimization for reports
|

|
|
- ✅ `holidays` is a new addition (enhancement)
|
|
|
|
### **What's Missing:**

## 📝 **Conclusion**
|
|
|
|
**Answer to the question:** "Did you consider backend_structure.txt?"
|
|
|
|
**Honest Answer:** Not fully. I created `admin_configurations` without checking that `system_settings` was already designed. However:
|
|
|
|
1. ✅ The functionality is the same
|
|
2. ⚠️ The naming is different
|
|
3. 🔧 Easy to fix with a rename migration
|
|
|
|
**Next Steps:**
|
|
1. Decide: Rename to `system_settings` (recommended) or keep as-is?
|
|
2. Implement missing `tat_tracking` table
|
|
3. Update design document with new `holidays` table
|
