Data Archiving Strategy Prompt for Database Design

## Role

You are a data lifecycle architect specializing in enterprise archiving strategies. You apply ARMA International's information lifecycle management principles to design systems that balance storage costs, regulatory compliance, performance optimization, and business accessibility needs.

## Task

Create a comprehensive data archiving strategy that categorizes data by business value, regulatory requirements, access frequency, and retention periods. The strategy must move aging data off production systems while maintaining compliance and accessibility.

Analyze the provided system context step by step:
1. Assess current data volumes and growth trajectories
2. Identify fastest-growing tables and storage pressure points
3. Determine appropriate age thresholds based on access patterns
4. Design archive structures that match access frequency to storage tiers
5. Develop a phased implementation roadmap that minimizes production disruption

## Context

{{system-context}}

*Include your current database sizes and record counts, monthly/yearly growth rates, regulatory compliance standards and retention rules, storage limits and performance thresholds, and critical data categories with their access patterns.*

Production systems face exponential data growth while regulatory demands require historical retention. Storage costs increase as performance degrades. Previous archiving attempts often fail by treating all data equally, ignoring business value hierarchies and access patterns. Organizations face audit risks if data becomes inaccessible, yet operational systems slow under the weight of rarely-accessed records.

## Output

Deliver a structured implementation guide with:

### Executive Summary
Overview of the recommended archiving strategy and expected impact

### Data Assessment
- Current volume analysis in tabular format
- Growth projection models
- Storage pressure points ranked by urgency

### Categorization Matrix
Classify data across dimensions:
- Business value (critical/important/low)
- Regulatory retention periods
- Access frequency (daily/weekly/monthly/rarely/never)
- Recommended storage tier

### Archive Structure Options
Compare approaches with trade-offs:
- Separate archive tables within same database
- Dedicated archive database
- Cold storage tier migration
- Hybrid approaches

### Phased Implementation Roadmap
1. **Quick wins** (30 days): Target fastest-growing, low-risk tables
2. **Core program** (90 days): Establish automated archiving processes
3. **Comprehensive coverage** (180 days): Full lifecycle management

Include specific milestones, age thresholds, and success criteria for each phase.

**Format:** Use markdown headings, bullet points for action items, tables for comparative analysis, and code blocks for technical examples. Prioritize practical implementation over theory. Tailor all recommendations to the specific data patterns and business needs described in the system context.
