Mike Swanson e4392afce9 docs: Document Dataforth test database system and troubleshooting 
Investigation and Documentation:
- Discovered and documented test database system on AD2 server
- Created comprehensive TEST_DATABASE_ARCHITECTURE.md with full system details
- Retrieved all key database files from AD2 (import.js, schema.sql, server configs)
- Documented data flow: DOS machines → NAS → AD2 → SQLite → Web interface
- Verified database health: 1,027,517 records, 1075 MB, dates back to 1990

Database System Architecture:
- SQLite database with Node.js/Express.js web server (port 3000)
- Automated import via Sync-FromNAS.ps1 (runs every 15 minutes)
- 8 log types supported: DSCLOG, 5BLOG, 7BLOG, 8BLOG, PWRLOG, SCTLOG, VASLOG, SHT
- FTS5 full-text search, comprehensive indexes for performance
- API endpoints: search, stats, export, datasheet generation

Troubleshooting Scripts Created:
- Database diagnostics: check-db-simple.ps1, test-db-directly.ps1
- Server status checks: check-node-running.ps1, check-db-server.ps1
- Performance analysis: check-db-performance.ps1, check-wal-files.ps1
- API testing: test-api-endpoint.ps1, test-query.js
- Import monitoring: check-new-records.ps1
- Database optimization attempts: api-js-optimized.js, api-js-fixed.js
- Deployment scripts: deploy-db-optimization.ps1, deploy-db-fix.ps1, restore-original.ps1

Key Findings:
- Database file healthy and queryable (verified with test-query.js)
- Node.js server not running (port 3000 closed) - root cause of web interface issues
- Database last updated 8 days ago (01/13/2026) - automated sync may be broken
- Attempted performance optimizations (WAL mode) incompatible with readonly connections
- Original api.js restored from backup after optimization conflicts

Retrieved Documentation:
- QUICKSTART-retrieved.md: Quick start guide for database server
- SESSION_NOTES-retrieved.md: Complete session notes from database creation
- Sync-FromNAS-retrieved.ps1: Full sync script with database import logic
- import-js-retrieved.js: Node.js import script (12,774 bytes)
- schema-retrieved.sql: SQLite schema with FTS5 triggers
- server-js-retrieved.js: Express.js server configuration
- api-js-retrieved.js: API routes and endpoints
- package-retrieved.json: Node.js dependencies

Action Items Identified:
1. Start Node.js server on AD2 to restore web interface functionality
2. Investigate why automated sync hasn't updated database in 8 days
3. Check Windows Task Scheduler for Sync-FromNAS.ps1 scheduled task
4. Run manual import to catch up on 8 days of test data if needed

Technical Details:
- Database path: C:\Shares\testdatadb\database\testdata.db
- Web interface: http://192.168.0.6:3000 (when running)
- Database size: 1075.14 MB (1,127,362,560 bytes)
- Total records: 1,027,517 (slight variance from original 1,030,940)
- Pass rate: 99.82% (1,029,046 passed, 1,888 failed)

Test Data Database - Session Notes

Session Date: 2026-01-13

Project Overview

Created a SQLite database with Express.js web interface to consolidate, deduplicate, and search test data from multiple backup dates and test stations.

Project Location

C:\Shares\TestDataDB\

Original Request

  • Search for serial numbers 176923-1 through 176923-26 in model DSCA38-1793
  • Serial numbers were NOT found in any existing .DAT files (most recent logged: 173672-x, 173681-x from Feb 2025)
  • User requested a database to consolidate all test data for easier searching

Data Sources

  • HISTLOGS: C:\Shares\test\Ate\HISTLOGS\ (consolidated history)
  • Recovery-TEST: C:\Shares\Recovery-TEST\ (6 backup dates: 12-13-25 to 12-18-25)
  • Live Data: C:\Shares\test\ (~540K files)
  • Test Stations: TS-1L, TS-3R, TS-4L, TS-4R, TS-8R, TS-10L, TS-11L

File Types Imported

Log Type Description Extension
DSCLOG DSC product line .DAT
5BLOG 5B product line .DAT
7BLOG 7B product line (CSV format) .DAT
8BLOG 8B product line .DAT
PWRLOG Power tests .DAT
SCTLOG SCT product line .DAT
VASLOG VAS tests .DAT
SHT Human-readable test sheets .SHT

API Endpoints

  • GET /api/search?serial=...&model=...&from=...&to=...&result=...&q=...
  • GET /api/record/:id
  • GET /api/datasheet/:id - Generate printable datasheet
  • GET /api/stats
  • GET /api/export?format=csv

How to Use

Start the server:

cd C:\Shares\TestDataDB
node server.js

Then open http://localhost:3000 in a browser.

Re-run import (if needed):

cd C:\Shares\TestDataDB
node database/import.js

Database Schema

  • Table: test_records
  • Columns: id, log_type, model_number, serial_number, test_date, test_station, overall_result, raw_data, source_file, import_date
  • Indexes on: serial_number, model_number, test_date, overall_result
  • Full-text search (FTS5) for searching raw_data

Features

  1. Search - By serial number, model number, date range, pass/fail status
  2. Full-text search - Search within raw test data
  3. Export - CSV export of search results
  4. Datasheet generation - Generate formatted test data sheets from any record
  5. Statistics - Dashboard showing total records, pass/fail counts, date range

By Result:

  • PASS: 1,029,046
  • FAIL: 1,888
  • UNKNOWN: 6

Current Status

Known Issues

  • Model number parsing needs re-import to fix (parser was updated but requires re-import)
  • To re-import: Delete testdata.db and run node database/import.js

Search Results for Original Request

  • Serial numbers 176923-1 through 176923-26: NOT FOUND (not yet tested)
  • Most recent serial for DSCA38-1793: 173672-x and 173681-x (February 2025)

Next Steps

  1. Re-run import if model number search is needed (delete testdata.db first)
  2. When serial numbers 176923-1 to 176923-26 are tested, they will appear in the database

Notes

  • TXT datasheets in 10D/datasheets/ are NOT imported (can be generated from DB)
  • Deduplication uses: (log_type, model_number, serial_number, test_date, test_station)
  • ~3,600 SHT files to import
  • ~41,000+ DAT files across all log types
