#### machinerelationships
Stores relationships between machines
- `relationshipid` - Primary key
- `machineid` - Source machine
- `related_machineid` - Target machine
- `relationshiptypeid` - Foreign key to relationshiptypes
- `isactive` - 1 for active

**Relationship Types:**

## Security Features

### SQL Injection Prevention
- **100% parameterized queries** throughout all files
- No string concatenation in SQL statements
- Uses `ADODB.Command` with typed parameters
- Helper function `ExecuteParameterizedQuery()` for consistency

**Example:**
```asp
Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = objConn
cmd.CommandText = "UPDATE machines SET modelid = ? WHERE machineid = ?"
cmd.Parameters.Append cmd.CreateParameter("@modelid", 3, 1, , CLng(modelid))
cmd.Parameters.Append cmd.CreateParameter("@machineid", 3, 1, , CLng(machineid))
cmd.Execute
```

### XSS Prevention
- All user data passed through `Server.HTMLEncode()`
- No raw output of user-supplied data
- HTML encoding on all displayed values

### Input Validation
- Server-side validation for all fields
- Numeric fields validated with `IsNumeric()`
- String length limits enforced
- Required fields checked before processing
- Pattern validation for IP addresses and MAC addresses

### Error Handling
- Graceful error messages
- "Go back" links on errors
- No sensitive data exposed in errors
- Database connection always closed properly
- NULL handling prevents type errors

3. INSERT into `machines` table → get new `machineid`
4. INSERT into `communications` table (up to 3 records for interfaces)
5. INSERT into `machinerelationships` table:
   - Controls: PC → Equipment (one record)
   - Dualpath: Equipment ↔ Dualpath Machine (two records, bidirectional)
6. INSERT into `compliance` table
7. Redirect to `displaymachine.asp?machineid=XXX`

### Edit Machine (savemachineedit.asp)
1. Validate `machineid` and verify machine exists
2. Handle nested entity creation (same as add)
3. UPDATE `machines` table (does NOT update `machinenumber`)
4. DELETE old communications: `DELETE FROM communications WHERE machineid = ?`
5. INSERT new communications (up to 3 records)
6. DELETE old relationships: `DELETE FROM machinerelationships WHERE machineid = ? OR related_machineid = ?`
7. INSERT new relationships (Controls + Dualpath)
8. UPDATE or INSERT compliance data:
   - If exists: UPDATE compliance SET ...
   - If not exists: INSERT INTO compliance ...
9. Redirect to `displaymachine.asp?machineid=XXX`

## Known Limitations

### 1. Communication Editing Strategy
- Uses DELETE then INSERT approach
- Does not preserve `comid` values
- Cannot edit individual interfaces (all or nothing)
- **Future enhancement**: Allow editing specific interfaces without deleting all

### 2. Relationship Editing Strategy
- Uses DELETE then INSERT approach
- Does not preserve `relationshipid` values
- Cannot view relationship history
- **Future enhancement**: Add relationship history tracking

### 3. Interface Limit
- Can only add/edit up to 3 interfaces via form
- Additional interfaces require database access
- **Future enhancement**: Dynamic interface addition with "Add Interface" button

### 4. File Naming
- Old file: `editmacine.asp` (typo)
- New file: `editmachine.asp` (correct spelling)
- Both exist for compatibility
- **Future enhancement**: Migrate all references and remove typo file

---

## Future Enhancements

### Short-term (Next Sprint)
1. **Add Interface** button for dynamic interface management
2. Client-side validation before form submission
3. Autosave draft changes
4. Confirmation before leaving with unsaved changes

### Medium-term (Next Quarter)
1. Field-level change tracking (audit trail)
2. Bulk edit multiple machines
3. Relationship history/audit trail
4. More relationship types (Shares Network, Backup Of, etc.)

### Long-term (Future)
1. Security scan integration with automated scanning
2. Compliance status tracking and alerts
3. Automated compliance checking
4. Real-time field validation
5. Machine dependency visualization (relationship graph)
