# PC to Machines Consolidation - Complete Design Document
|
||||
|
||||
**Date Created**: 2025-11-06
|
||||
**Status**: DESIGN PHASE
|
||||
**Complexity**: ⚠️ **CRITICAL - MASSIVE REFACTORING**
|
||||
**Production Deployment**: All SQL changes must be tracked
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines the plan to consolidate the `pc` table (277 records) into the `machines` table (266 records) and implement a generic communications infrastructure.
|
||||
|
||||
**Goals:**
|
||||
1. Eliminate the `pc` table by migrating all data into `machines`
|
||||
2. Create a generic `communications` system supporting multiple communication types (IP, Serial, etc.)
|
||||
3. Maintain all existing functionality through views and code updates
|
||||
4. Enable future extensibility for new communication types
|
||||
|
||||
**Impact:**
|
||||
- **Tables to modify**: 12+
|
||||
- **Views to update**: 19
|
||||
- **ASP files**: TBD (likely 50+)
|
||||
- **Data records**: 543 machines total (266 current + 277 PCs)
|
||||

|
||||
|
||||
### 2.3 Modified Machines Table
|
||||
|
||||
Add new fields to support PC data and communications:
|
||||
|
||||
**NOTE**: Warranty fields are NOT added to machines table. See WARRANTY_MANAGEMENT_DESIGN.md for the separate warranty infrastructure.
|
||||
|
||||
```sql
|
||||
ALTER TABLE machines
|
||||
-- PC-specific fields
|
||||
ADD COLUMN hostname VARCHAR(100) AFTER machinenumber,
|
||||
ADD COLUMN serialnumber VARCHAR(100) AFTER modelnumberid,
|
||||
ADD COLUMN loggedinuser VARCHAR(100) AFTER hostname,
|
||||
ADD COLUMN osid INT(11) AFTER modelnumberid,
|
||||
ADD COLUMN pcstatusid INT(11) AFTER osid,
|
||||
ADD COLUMN pctypeid INT(11) AFTER machinetypeid,
|
||||
|
||||
-- Configuration flags
|
||||
ADD COLUMN requires_manual_machine_config TINYINT(1) DEFAULT 0,
|
||||
|
||||
-- Audit fields
|
||||
ADD COLUMN lastupdated DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

ADD CONSTRAINT fk_machines_pcstatusid FOREIGN KEY (pcstatusid) REFERENCES pcstatus(pcstatusid),
|
||||
ADD CONSTRAINT fk_machines_pctypeid FOREIGN KEY (pctypeid) REFERENCES pctype(pctypeid);
|

## Part 3: Migration Strategy
|
||||
|
||||
### 3.1 Migration Phases
|
||||
|
||||
**Phase 1: Schema Preparation** (REVERSIBLE)
|
||||
1. Create `comstypes` table
|
||||
2. Create `communications` table
|
||||
3. Add new columns to `machines` table
|
||||
4. Create backup tables
|
||||
|
||||
**Phase 2: Data Migration** (REVERSIBLE with backup)
|
||||
1. Migrate PC records to machines table
|
||||
2. Migrate PC communication data to communications table
|
||||
3. Migrate network interface data to communications table
|
||||
4. Migrate DNC configuration to communications or new DNC table
|
||||
5. Update relationship tables
|
||||
|
||||
**Phase 3: Reference Updates** (REQUIRES TESTING)
|
||||
1. Create compatibility views (pc → machines)
|
||||
2. Update dependent tables
|
||||
3. Update 19 existing views
|
||||
|
||||
**Phase 4: Application Updates** (REQUIRES EXTENSIVE TESTING)
|
||||
1. Update ASP files
|
||||
2. Update stored procedures (if any)
|
||||
3. Test all functionality
|
||||
|
||||
**Phase 5: Cleanup** (IRREVERSIBLE - DO AFTER 30 DAYS)
|
||||
1. Drop old `pc` table
|
||||
2. Drop compatibility views
|
||||
3. Remove deprecated ipaddress1/ipaddress2 from machines
|
||||
|
||||
### 3.2 Machine Type for PCs
|
||||
|
||||
We need to add machine types for PCs:
|
||||
|
||||
```sql
|
||||
INSERT INTO machinetypes (machinetype, machinedescription, functionalaccountid, isactive)
|
||||
VALUES
|
||||
('PC - Standard', 'Standard office/engineering workstation', (SELECT functionalaccountid FROM functionalaccounts WHERE functionalaccount = 'IT' LIMIT 1), 1),
|
||||
('PC - Shopfloor', 'Shopfloor machine control PC', (SELECT functionalaccountid FROM functionalaccounts WHERE functionalaccount = 'MFG' LIMIT 1), 1),
|
||||
('PC - Engineer', 'Engineering workstation', (SELECT functionalaccountid FROM functionalaccounts WHERE functionalaccount = 'ENG' LIMIT 1), 1);
|
||||
```
|
||||
|
||||
### 3.3 Data Mapping: PC → Machines
|
||||
|
||||
| PC Field | Machines Field | Notes |
|
||||
|----------|---------------|-------|
|
||||
| pcid | machineid | New auto-increment ID |
|
||||
| hostname | hostname | NEW COLUMN |
|
||||
| serialnumber | serialnumber | NEW COLUMN |
|
||||
| loggedinuser | loggedinuser | NEW COLUMN |
|
||||

|
||||
| requires_manual_machine_config | requires_manual_machine_config | NEW COLUMN |
|
||||
| osid | osid | NEW COLUMN, FK preserved |
|
||||
| pcstatusid | pcstatusid | NEW COLUMN, FK preserved |
|
||||
| N/A | machinetypeid | Map from pctypeid to new machine types |
|
||||
| N/A | alias | Set to hostname for PCs |
|
||||
| N/A | businessunitid | Default to 1 or derive from location |
|
||||
|
||||
**Warranty Fields**: Migrated to `warranties` table (see WARRANTY_MANAGEMENT_DESIGN.md)
|
||||
- warrantyenddate → warranties.enddate
|
||||
- warrantystatus → warranties.status
|
||||
- warrantyservicelevel → warranties.servicelevel
|
||||
- warrantylastchecked → warranties.lastcheckeddate
|
||||
|
||||

|
||||
|
||||
| Old Field | New Field | New comstypeid |
|
||||
|-----------|-----------|----------------|
|
||||

||||
|
||||
| Old Field | New Field | New comstypeid |
|
||||
|-----------|-----------|----------------|
|
||||

|

|
||||
## Part 6: Next Steps & Considerations
|
||||
|
||||
### 6.1 Critical Decisions Needed
|
||||
|
||||
1. **DNC Configuration**:
|
||||
- Keep pc_dnc_config as-is but reference machines instead of pc?
|
||||
- Or migrate to communications table with comstypeid='DNC'?
|
||||
- **Recommendation**: Keep separate, too complex for generic table
|
||||
|
||||
2. **Machine Overrides**:
|
||||
- Keep machine_overrides table?
|
||||
- **Recommendation**: Yes, but update FK to machines
|
||||
|
||||
3. **Warranty Management**:
|
||||
- Extend to all machines or keep PC-specific?
|
||||
- **Recommendation**: Available for all machines
|
||||
|
||||
4. **Machine Numbers**:
|
||||
- PCs currently link to machines via machinenumber (string match)
|
||||
- After migration, use direct machineid FK
|
||||
- **Recommendation**: Add explicit FK relationships
|
||||
|
||||
### 6.2 Testing Requirements
|
||||
|
||||
1. **Data Integrity**:
|
||||
- Verify all 277 PCs migrated
|
||||
- Verify all communication records migrated
|
||||
- Verify all FK relationships intact
|
||||
|
||||
2. **View Testing**:
|
||||
- Test all 19 views return same data
|
||||
- Performance testing for complex views
|
||||
|
||||
3. **Application Testing**:
|
||||
- Test every ASP file that touches pc table
|
||||
- Test all CRUD operations
|
||||
- Test warranty tracking
|
||||
- Test DNC configuration
|
||||
|
||||
### 6.3 Production Deployment Checklist
|
||||
|
||||
- [ ] Create full database backup
|
||||
- [ ] Test migration on dev environment
|
||||
- [ ] Create compatibility views for old queries
|
||||
- [ ] Update all ASP files
|
||||
- [ ] Schedule maintenance window (4-6 hours recommended)
|
||||
- [ ] Prepare rollback procedure
|
||||
- [ ] Document all changes
|
||||
- [ ] Train users on any UI changes
|
||||
