# Industrial Specification: Database Engine

## 1. Technical Definition
Core software component responsible for storing, retrieving, and managing data within SCADA/MES systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-85°C ambient temperature, 20-80% relative humidity non-condensing**. Failure boundary: **Sustained CPU temperature &gt;95°C for &gt;30 minutes or memory utilization &gt;95% for &gt;1 hour**, Mechanism: **Thermal runaway in silicon junctions exceeding 125°C causes electron migration and gate oxide breakdown, while memory saturation triggers thrashing where paging overhead exceeds useful work**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Write amplification exceeding 3:1 ratio in flash-based storage | 8 | NAND cell endurance exhaustion at 3000 P/E cycles causing uncorrectable ECC errors | Implement wear-leveling algorithms with 15% over-provisioning and ZNS (Zoned Namespace) interface |
| Transaction log sequential write latency exceeding 10ms at 4KB block size | 8 | Write-ahead logging failure causing ACID compliance violation and data corruption | Dual-phase commit protocol with battery-backed NVDIMM for log persistence |
