# Database Discovery Agent Architecture (Conceptual Design)

## Overview

This document describes a conceptual architecture for an AI-powered database discovery agent that could autonomously explore, understand, and analyze any database schema regardless of complexity or domain. The agent would use a mixture-of-experts approach where specialized LLM agents collaborate to build comprehensive understanding of database structures, data patterns, and business semantics.

**Note:** This is a conceptual design document. The actual ProxySQL MCP implementation uses a different approach based on the two-phase discovery architecture described in `Two_Phase_Discovery_Implementation.md`.

## Core Principles

1. **Domain Agnostic** - No assumptions about what the database contains; everything is discovered
2. **Iterative Exploration** - Not a one-time schema dump; continuous learning through multiple cycles
3. **Collaborative Intelligence** - Multiple experts with different perspectives work together
4. **Hypothesis-Driven** - Experts form hypotheses, test them, and refine understanding
5. **Confidence-Based** - Exploration continues until a confidence threshold is reached

## High-Level Architecture

- Detect table hierarchies and dependencies
- Identify structural patterns (star schema, snowflake, hierarchical, etc.)

**Exploration Strategy:**
```python
class StructuralExpert:
    def explore(self, catalog):
        # Iteration 1: Map the territory
        tables = self.list_all_tables()
        for table in tables:
            schema = self.get_table_schema(table)
            relationships = self.find_relationships(table)

            catalog.save("structure", f"table.{table}", {

            if joins:
                catalog.save("relationship", f"{table_a}↔{table_b}", joins)

        # Iteration 3: Identify structural patterns
        patterns = self.identify_patterns(catalog)
        # "This looks like a star schema", "Hierarchical structure", etc.
```

**Output Examples:**
- "Found 47 tables across 3 schemas"

        tables = catalog.get_kind("table.*")

        for table in tables:
            # Profile each column
            for col in table["columns"]:
                stats = self.get_column_stats(table, col)

                    "anomalies": stats["outliers"]
                })

        # Find correlations
        correlations = self.find_correlations(tables)
        catalog.save("patterns", "correlations", correlations)
```

**Output Examples:**
- "orders.status has 4 values: pending (23%), confirmed (45%), shipped (28%), cancelled (4%)"
- "Strong correlation (0.87) between order_items.quantity and order_total"
- "Outlier detected: customer_age has values > 150 (likely data error)"

class SemanticExpert:
    def explore(self, catalog):
        # Synthesize findings from other experts
        structure = catalog.get_kind("structure.*")
        stats = catalog.get_kind("statistics.*")

        for table in structure:
            # Infer domain from table name, columns, and data
            domain = self.infer_domain(table, stats)
            # "This is an ecommerce database"

            # Understand entities
            entity_type = self.identify_entity(table)
            # "customers table = Customer entities"

            # Understand relationships
            for rel in catalog.get_relationships(table):
                business_rel = self.interpret_relationship(rel)
                # "customer has many orders"
                catalog.save("semantic", f"rel.{table}.{other}", {
                    "relationship": business_rel,
                    "cardinality": "one-to-many",
                    "business_rule": "A customer can place multiple orders"
                })

        # Identify business processes
        processes = self.infer_processes(structure, stats)
        # "Order fulfillment flow: orders → order_items → products"
        catalog.save("semantic", "processes", processes)
```

**Output Examples:**
- "Domain inference: E-commerce platform (B2C)"
- "Entity: customers represents individual shoppers, not businesses"
- "Business process: Order lifecycle = pending → confirmed → shipped → delivered"
- "Business rule: Customer cannot be deleted if they have active orders"

### 4. Query Expert

**Focus:** Efficient data access patterns

**Responsibilities:**
- Analyze query optimization opportunities
- Recommend index usage strategies
- Determine optimal join orders
- Design sampling strategies for exploration
- Identify performance bottlenecks

**Exploration Strategy:**

class QueryExpert:
    def explore(self, catalog):
        # Analyze query patterns from structural expert
        structure = catalog.get_kind("structure.*")

        for table in structure:
            # Suggest optimal access patterns
            access_patterns = self.analyze_access_patterns(table)
            catalog.save("query", f"access.{table}", {
                "best_index": access_patterns["optimal_index"],
                "join_order": access_patterns["optimal_join_order"],
                "sampling_strategy": access_patterns["sample_method"]
            })
```

**Output Examples:**
- "For customers table, use idx_email for lookups, idx_created_at for time ranges"
- "Join order: customers → orders → order_items (not reverse)"
- "Sample strategy: Use TABLESAMPLE for large tables, LIMIT 1000 for small"

## Domain-Agnostic Discovery Examples

### Example 1: Law Firm Database

**Phase 1-5 (Blind):**
```
Structural: "Found: cases, clients, attorneys, documents, time_entries, billing_rates"
Statistical: "time_entries has 1.2M rows, highly skewed distribution, 15% null values"
Semantic: "Entity types: Cases (legal matters), Clients (people/companies), Attorneys"
Query: "Best access path: case_id → time_entries (indexed)"
```

**Phase 6-15 (Patterns):**
```
Collaboration:
  Structural → Semantic: "cases have many-to-many with attorneys (case_attorneys table)"
  Semantic: "Multiple attorneys per case = legal teams"
  Statistical: "time_entries correlate with case_stage progression (r=0.72)"
  Query: "Filter by case_date_first for time range queries (30% faster)"

Domain Inference:
  Semantic: "Legal practice management system"
  Structural: "Found invoices, payments tables - confirms practice management"
  Statistical: "Billing patterns: hourly rates, contingency fees detected"
```

**Phase 16-30 (Hypotheses):**
```
Hypothesis: "Firm specializes in specific case types"
→ Statistical: "Analyze case_type distribution"
→ Found: "70% personal_injury, 20% corporate_litigation, 10% family_law"

Hypothesis: "Document workflow exists"
→ Structural: "Found document_versions, approvals, court_filings tables"
→ Semantic: "Document approval workflow for court submissions"

Hypothesis: "Attorney productivity varies by case type"
→ Statistical: "Analyze time_entries per attorney per case_type"
→ Found: "Personal injury cases require 3.2x more attorney hours"
```

**Phase 31-40 (Synthesis):**
```
Final Understanding:
"Mid-sized personal injury law firm (50-100 attorneys)
with practice management system including:
- Case management with document workflows
- Time tracking and billing (hourly + contingency)

Patterns: "Experiments follow protocol → samples → measurements → analysis pipeline"
Structural: "Linear workflow: protocols → experiments → samples → measurements → analysis → publications"
Statistical: "High correlation between protocol_type and measurement_outcome"
```

**Phase 16-30 (Hypotheses):**
```
Hypothesis: "Longitudinal study design"
→ Structural: "Found repeated_measurements, time_points tables"

→ Found: "Peak: Nov-Dec (holidays), Dip: Jan, Slow: Feb-Mar"
```

**Phase 31-40 (Synthesis):**
```
Final Understanding:
"Consumer ecommerce platform with:
- 5.4M orders, steady growth, strong seasonality
- 3 customer segments (Casual/Regular/VIP) with different behaviors
- 15% overall return rate (varies by category)
- Peak season: Nov-Dec (4.3x normal volume)
- Key metrics: conversion rate, AOV, customer lifetime value, return rate"
```

## Catalog Schema

The catalog serves as shared memory for all experts. Key entry types:

### Structure Entries
```json

    "foreign_keys": [{"column": "region_id", "references": "regions(id)"}],
    "row_count": 125000
  },
  "tags": "customers,table"
}
```

### Statistics Entries
```json

  "kind": "statistics",
  "key": "customers.created_at",
  "document": {
    "distinct_count": 118500,

    "distribution": "uniform_growth"
  },
  "tags": "customers,created_at,temporal"
}
```

### Semantic Entries
```json

  "document": {
    "entity_type": "Customer",
    "definition": "Individual shoppers who place orders",
    "business_role": "Revenue generator",
    "lifecycle": "Registered → Active → Inactive → Churned"
  },
  "tags": "semantic,entity,customers"
}
```

### Relationship Entries
```json
{
  "kind": "relationship",
  "key": "customers↔orders",
  "document": {
    "type": "one_to_many",
    "join_key": "customer_id",
    "business_meaning": "Customers place multiple orders",
    "cardinality_estimates": {
      "min_orders_per_customer": 1,
      "max_orders_per_customer": 247,
      "avg_orders_per_customer": 4.3
    }
  },
  "tags": "relationship,customers,orders"
}
```

### Hypothesis Entries
```json
{
  "kind": "hypothesis",
  "key": "vip_segment_behavior",
  "document": {
    "hypothesis": "VIP customers have higher order frequency and AOV",
    "status": "confirmed",
    "confidence": 0.92,
    "evidence": [
      "VIP avg 12.4 orders/year vs 2.1 for regular",
      "VIP avg AOV $156 vs $45 for regular"
    ]
  },
  "tags": "hypothesis,customer_segments,confirmed"
}
```

### Collaboration Entries
```json
{
  "kind": "collaboration",
  "key": "semantic_interpretation_001",
  "document": {
    "trigger": "Structural expert found orders.status enum",
    "expert": "semantic",
    "interpretation": "Order lifecycle: pending → confirmed → shipped → delivered",
    "follow_up_tasks": ["Analyze time_in_status durations", "Find bottleneck status"]
  },
  "tags": "collaboration,structural,semantic,order_lifecycle"
}
```

## Stopping Criteria

The orchestrator evaluates whether to continue exploration based on:

1. **Confidence Threshold** - Overall confidence in understanding exceeds target (e.g., 0.95)
2. **Coverage Threshold** - Sufficient percentage of database explored (e.g., 95% of tables analyzed)
3. **Diminishing Returns** - Last N iterations produced minimal new insights
4. **Resource Limits** - Maximum iterations reached or time budget exceeded
5. **Expert Consensus** - All experts indicate satisfactory understanding

```python
def should_stop(self):
    # High confidence in core understanding
    if self.state["confidence"] >= 0.95:
        return True, "Confidence threshold reached"

    # Good coverage of database
    if self.state["coverage"] >= 0.95:
        return True, "Coverage threshold reached"

    # Diminishing returns
    if self.state["recent_insights"] < 2:
        self.state["diminishing_returns"] += 1
        if self.state["diminishing_returns"] >= 3:
            return True, "Diminishing returns"

    # Expert consensus
    if all(expert.satisfied() for expert in self.experts):
        return True, "Expert consensus achieved"

    return False, "Continue exploration"
```

## Implementation Considerations

### Scalability

For large databases (hundreds/thousands of tables):
- **Parallel Exploration**: Experts work simultaneously on different table subsets
- **Incremental Coverage**: Prioritize important tables (many relationships, high cardinality)
- **Smart Sampling**: Use statistical sampling instead of full scans for large tables
- **Progressive Refinement**: Start with overview, drill down iteratively

### Performance

- **Caching**: Cache catalog queries to avoid repeated reads
- **Batch Operations**: Group multiple tool calls when possible
- **Index-Aware**: Let Query Expert guide exploration to use indexed columns
- **Connection Pooling**: Reuse database connections (already implemented in MCP)

### Error Handling

- **Graceful Degradation**: If one expert fails, others continue
- **Retry Logic**: Transient errors trigger retries with backoff
- **Partial Results**: Catalog stores partial findings if interrupted
- **Validation**: Experts cross-validate each other's findings

### Extensibility

- **Pluggable Experts**: New expert types can be added easily
- **Domain-Specific Experts**: Specialized experts for healthcare, finance, etc.
- **Custom Tools**: Additional MCP tools for specific analysis needs
- **Expert Configuration**: Experts can be configured/enabled based on needs

## Usage Example

```python
from discovery_agent import DiscoveryOrchestrator

# Initialize agent
agent = DiscoveryOrchestrator(
    mcp_endpoint="https://localhost:6071/mcp/query",
    auth_token="your_token"
)

# Run discovery
report = agent.discover(
    max_iterations=50,
    target_confidence=0.95
)

# Access findings
print(report["summary"])
print(report["domain"])
print(report["key_insights"])

# Query catalog for specific information
customers_analysis = agent.catalog.search("customers")
relationships = agent.catalog.get_kind("relationship")
```
