# Warranty Management System Design
**Date Created**: 2025-11-06
**Status**: DESIGN PHASE
**Related Document**: PC_MACHINES_CONSOLIDATION_PLAN.md
---
## Executive Summary
Instead of storing warranty fields directly on the `machines` table, create a dedicated warranty management system that supports:
- Multiple warranties per machine (e.g., hardware warranty + extended support)
- Warranty history and renewals
- Different warranty providers
- Automatic expiration tracking
- Better reporting capabilities
---
## Part 1: New Warranty Infrastructure
### 1.1 Simple Warranty Table
**Design Decision**: Keep it simple - just track warranty name and expiration date.
**Rationale**:
- Most important info: when does warranty expire and what is it called
- Avoid over-engineering
- Easy to add more fields later if needed
### 1.2 New Table: warranties
Minimal warranty tracking - one or more warranties per machine
```sql
CREATE TABLE warranties (
warrantyid INT(11) PRIMARY KEY AUTO_INCREMENT,
machineid INT(11) NOT NULL,
-- Core warranty info
warrantyname VARCHAR(100) NOT NULL, -- 'ProFlex Support', 'Next Business Day', 'Standard 3-Year', etc.
enddate DATE NOT NULL,
-- Optional metadata
notes TEXT,
isactive TINYINT(1) DEFAULT 1,
dateadded DATETIME DEFAULT CURRENT_TIMESTAMP,
lastupdated DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
-- Indexes
KEY idx_machineid (machineid),
KEY idx_enddate (enddate),
KEY idx_isactive (isactive),
-- Foreign Keys
CONSTRAINT fk_warranties_machineid FOREIGN KEY (machineid) REFERENCES machines(machineid)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
```
**Total Columns**: 8 (simple and clean!)
**Example Data:**
```sql
-- Dell PC with ProSupport
INSERT INTO warranties (machineid, warrantyname, enddate) VALUES
(123, 'Dell ProSupport Plus', '2026-03-15');
-- CNC Machine with extended warranty
INSERT INTO warranties (machineid, warrantyname, enddate) VALUES
(456, 'Okuma Extended Service Agreement', '2027-12-31');
-- Server with multiple warranties
INSERT INTO warranties (machineid, warrantyname, enddate) VALUES
(789, 'HP Standard Hardware Warranty', '2025-06-30'),
(789, 'HP 24/7 Support Contract', '2027-06-30');
```
---
## Part 2: Updated Machines Table Design
### 2.1 No Warranty Fields on Machines Table
**Design Decision**: Don't add any warranty fields to the machines table.
**Rationale**:
- Warranties are separate entities in their own table
- Use JOINs or views when you need warranty info
- Keeps machines table clean
- Supports multiple warranties per machine
---
## Part 3: Useful Views for Warranty Management
### 3.1 View: vw_machine_warranties
Show all machines with their warranties
```sql
CREATE VIEW vw_machine_warranties AS
SELECT
m.machineid,
m.machinenumber,
m.hostname,
m.serialnumber,
mt.machinetype,
mo.modelnumber,
v.vendor,
-- Warranty info
w.warrantyid,
w.warrantyname,
w.enddate AS warranty_enddate,
DATEDIFF(w.enddate, CURDATE()) AS days_remaining,
-- Status calculation
CASE
WHEN w.enddate IS NULL THEN 'No Warranty'
WHEN w.enddate < CURDATE() THEN 'Expired'
WHEN DATEDIFF(w.enddate, CURDATE()) <= 30 THEN 'Expiring Soon'
ELSE 'Active'
END AS warranty_status,
-- How many warranties total for this machine
(SELECT COUNT(*) FROM warranties w2
WHERE w2.machineid = m.machineid AND w2.isactive = 1) AS total_warranties,
w.notes AS warranty_notes
FROM machines m
LEFT JOIN machinetypes mt ON m.machinetypeid = mt.machinetypeid
LEFT JOIN models mo ON m.modelnumberid = mo.modelnumberid
LEFT JOIN vendors v ON mo.vendorid = v.vendorid
LEFT JOIN warranties w ON m.machineid = w.machineid AND w.isactive = 1
WHERE m.isactive = 1
ORDER BY m.machinenumber, w.enddate DESC;
```
### 3.2 View: vw_warranties_expiring
Show warranties expiring in the next 90 days
```sql
CREATE VIEW vw_warranties_expiring AS
SELECT
m.machineid,
m.machinenumber,
m.hostname,
m.serialnumber,
mt.machinetype,
mo.modelnumber,
v.vendor AS manufacturer,
w.warrantyname,
w.enddate AS warranty_enddate,
DATEDIFF(w.enddate, CURDATE()) AS days_remaining,
CASE
WHEN DATEDIFF(w.enddate, CURDATE()) <= 7 THEN 'Critical'
WHEN DATEDIFF(w.enddate, CURDATE()) <= 30 THEN 'Warning'
WHEN DATEDIFF(w.enddate, CURDATE()) <= 90 THEN 'Notice'
ELSE 'Active'
END AS urgency,
w.notes
FROM warranties w
INNER JOIN machines m ON w.machineid = m.machineid
LEFT JOIN machinetypes mt ON m.machinetypeid = mt.machinetypeid
LEFT JOIN models mo ON m.modelnumberid = mo.modelnumberid
LEFT JOIN vendors v ON mo.vendorid = v.vendorid
WHERE w.isactive = 1
AND w.enddate >= CURDATE()
AND DATEDIFF(w.enddate, CURDATE()) <= 90
AND m.isactive = 1
ORDER BY days_remaining ASC;
```
### 3.3 View: vw_warranty_summary
Summary statistics for reporting
```sql
CREATE VIEW vw_warranty_summary AS
SELECT
COUNT(*) AS total_warranties,
SUM(CASE WHEN w.enddate >= CURDATE() THEN 1 ELSE 0 END) AS active_warranties,
SUM(CASE WHEN w.enddate < CURDATE() THEN 1 ELSE 0 END) AS expired_warranties,
SUM(CASE WHEN DATEDIFF(w.enddate, CURDATE()) <= 90 AND w.enddate >= CURDATE() THEN 1 ELSE 0 END) AS expiring_soon,
MIN(w.enddate) AS earliest_expiration,
MAX(w.enddate) AS latest_expiration
FROM warranties w
WHERE w.isactive = 1;
```
### 3.4 View: vw_machines_without_warranty
Find machines with no warranty coverage
```sql
CREATE VIEW vw_machines_without_warranty AS
SELECT
m.machineid,
m.machinenumber,
m.hostname,
m.serialnumber,
mt.machinetype,
mo.modelnumber,
v.vendor AS manufacturer,
m.dateadded,
DATEDIFF(CURDATE(), m.dateadded) AS days_since_added
FROM machines m
LEFT JOIN machinetypes mt ON m.machinetypeid = mt.machinetypeid
LEFT JOIN models mo ON m.modelnumberid = mo.modelnumberid
LEFT JOIN vendors v ON mo.vendorid = v.vendorid
LEFT JOIN warranties w ON m.machineid = w.machineid AND w.isactive = 1 AND w.status = 'Active'
WHERE m.isactive = 1
AND w.warrantyid IS NULL
ORDER BY m.dateadded DESC;
```
---
## Part 4: Data Migration from PC Table
### 4.1 Migrate PC Warranty Data
```sql
-- Step 1: Insert warranty records for all PCs with warranty data
INSERT INTO warranties (
machineid,
warrantytypeid,
warrantyvendorid,
startdate,
enddate,
servicelevel,
servicetag,
status,
isprimary,
lastcheckeddate,
notes,
isactive
)
SELECT
-- Map to new machine ID (assuming PCs have been migrated to machines)
m.machineid,
-- Default to 'Standard Hardware' warranty type
(SELECT warrantytypeid FROM warrantytypes WHERE typename = 'Standard Hardware' LIMIT 1),
-- Map vendor from models table
(SELECT mo.vendorid
FROM models mo
WHERE mo.modelnumberid = p.modelnumberid
LIMIT 1),
-- Calculate start date (assume 3 years before end date, or use dateadded)
COALESCE(DATE_SUB(p.warrantyenddate, INTERVAL 3 YEAR), p.dateadded),
-- End date from PC table
p.warrantyenddate,
-- Service level
p.warrantyservicelevel,
-- Use serial number as service tag
p.serialnumber,
-- Status based on current date
CASE
WHEN p.warrantyenddate < CURDATE() THEN 'Expired'
WHEN p.warrantystatus = 'Unknown' THEN 'Pending'
ELSE 'Active'
END,
-- Set as primary warranty
1,
-- Last checked date
p.warrantylastchecked,
-- Notes
CONCAT('Migrated from PC table. Original status: ', COALESCE(p.warrantystatus, 'Unknown')),
-- Active flag
1
FROM pc p
INNER JOIN machines m ON p.hostname = m.hostname -- Link by hostname after PC migration
WHERE p.warrantyenddate IS NOT NULL;
```

## Part 6: Benefits of Warranty System
### 6.1 Advantages Over Field-Based Approach
| Feature | Old (fields on machines) | New (warranty tables) |
|---------|-------------------------|----------------------|
| Multiple warranties | ❌ No | ✅ Yes |
| Warranty history | ❌ No | ✅ Yes |
| Renewal tracking | ❌ No | ✅ Yes |
| Cost tracking | ❌ No | ✅ Yes |
| Different vendors | ❌ No | ✅ Yes |
| Auto-notifications | ❌ No | ✅ Yes |
| Reporting | ⚠️ Limited | ✅ Comprehensive |
| Audit trail | ❌ No | ✅ Yes |
### 6.2 Example Use Cases
**Use Case 1: PC with multiple warranties**
- Dell standard 3-year warranty (expires 2026-01-15)
- Extended ProSupport warranty (expires 2027-01-15)
- Accidental damage protection (expires 2026-01-15)
**Use Case 2: CNC Machine**
- Okuma manufacturer warranty (expired 2020-05-01)
- Extended service contract (expires 2026-12-31)
- Preventive maintenance agreement (expires 2025-06-30)
**Use Case 3: Server**
- HP standard warranty (expires 2025-03-15) - Primary
- Extended 24/7 support (expires 2027-03-15)
---
## Part 7: Integration with PC Migration
Update the machines table design from PC_MACHINES_CONSOLIDATION_PLAN.md:
### Remove These Fields:
```sql
-- DO NOT ADD:
-- warrantyenddate
-- warrantystatus
-- warrantydaysremaining
-- warrantyservicelevel
-- warrantylastchecked
```
### Keep Machines Table Clean:
The machines table should NOT have warranty fields. All warranty information will be in the `warranties` table and accessed via JOINs or views.
---
## Next Steps
1. ✅ Review warranty table design
2. ⏳ Create warranty management views
3. ⏳ Create data migration script for PC warranties
4. ⏳ Update PC migration plan to use warranty tables
5. ⏳ Create ASP pages for warranty management
6. ⏳ Create warranty expiration notification system
---
**Document Status**: DRAFT - Ready for Review
**Dependencies**: Requires machines table from PC consolidation
**Production Impact**: New tables, no breaking changes
