SEDQL Python SDK

Python SDK for SED (Semantic Entities Designs) - Full TypeScript CLI Integration

SED automatically converts your raw database into an AI-ready semantic layer with intelligent business rules.

🚀 Quick Start

Installation

# Install the Python package
pip install sedql

# Install the SED CLI (required)
npm install -g sed-cli

Basic Usage

from sedql import SEDClient

# Initialize enhanced client (no database URL needed)
sed = SEDClient()

# Initialize SED with database connection
sed.init()

# Build semantic layer
sed.build()

# Query with natural language
result = sed.query("Show me customers with high revenue")
print(result)

# Query with AI integration using environment variables (RECOMMENDED)
# Set your API keys in environment variables:
# export OPENAI_API_KEY="your-openai-api-key"
# export ANTHROPIC_API_KEY="your-anthropic-api-key"

# Simple OpenAI query (automatically uses OPENAI_API_KEY)
ai_result = sed.query_with_openai("Forecast revenue for Q3 2024")

# Simple Anthropic query (automatically uses ANTHROPIC_API_KEY)
claude_result = sed.query_with_anthropic("Identify customer retention opportunities")

# Access rich response with all features
print(f"Data: {ai_result['query_result']}")
print(f"AI Analysis: {ai_result['ai_enhancement']['ai_response']}")
print(f"Risk Level: {ai_result['risk_assessment']['risk_level']}")
print(f"Business Context: {ai_result['business_context']}")

# Advanced: Use your own AI client
import openai
openai_client = openai.OpenAI(api_key="your-key")  # Only if you prefer this approach

custom_ai_result = sed.query_with_ai({
    "natural_language": "Analyze sales patterns",
    "ai_client": openai_client,
    "ai_service": "custom",
    "ai_model": "gpt-4"
})

🔗 AI Integration Examples

Environment Variables (RECOMMENDED)

from sedql import SEDClient

# Set environment variables first:
# export OPENAI_API_KEY="your-key"
# export ANTHROPIC_API_KEY="your-key"

# Initialize SED
sed = SEDClient()
sed.init()
sed.build()

# Simple queries using environment variables
openai_result = sed.query_with_openai("Analyze customer retention patterns")
claude_result = sed.query_with_anthropic("Identify revenue optimization opportunities")

print(f"OpenAI Analysis: {openai_result['ai_enhancement']['ai_response']}")
print(f"Claude Analysis: {claude_result['ai_enhancement']['ai_response']}")

OpenAI Integration (Manual)

import openai
from sedql import SEDClient

# Initialize SED
sed = SEDClient()
sed.init()
sed.build()

# Set up OpenAI client
openai_client = openai.OpenAI(api_key="your-openai-api-key")

# Query with AI enhancement
result = sed.query_with_ai({
    "natural_language": "Analyze customer retention patterns",
    "ai_client": openai_client,
    "ai_service": "custom",
    "ai_model": "gpt-4"
})

print(f"AI Analysis: {result['ai_enhancement']['ai_response']}")

Anthropic Integration (Manual)

import anthropic
from sedql import SEDClient

# Initialize SED
sed = SEDClient()
sed.init()
sed.build()

# Set up Anthropic client
anthropic_client = anthropic.Anthropic(api_key="your-anthropic-api-key")

# Query with AI enhancement
result = sed.query_with_ai({
    "natural_language": "Identify revenue optimization opportunities",
    "ai_client": anthropic_client,
    "ai_service": "custom",
    "ai_model": "claude-3-sonnet-20240229"
})

print(f"AI Analysis: {result['ai_enhancement']['ai_response']}")

Custom AI Service Integration

from sedql import SEDClient

# Your custom AI service
class CustomAIService:
    def generate(self, prompt, max_tokens=1000):
        # Your AI logic here
        return f"AI analysis: {prompt[:50]}..."

# Initialize SED
sed = SEDClient()
sed.init()
sed.build()

# Use your custom AI service
custom_ai = CustomAIService()

result = sed.query_with_ai({
    "natural_language": "Forecast sales for next quarter",
    "ai_client": custom_ai,
    "ai_model": "custom-model"
})

print(f"Custom AI Analysis: {result['ai_enhancement']['ai_response']}")

🎯 How AI Integration Works

SED's Role (What We Provide)

• 🔒 Security & Governance: Business rules, PII protection, access control
• 🏗️ Business Context: Semantic layer, entity relationships, business logic
• ✅ Query Validation: Ensures AI requests are safe and compliant
• 📊 Data Access: Secure database queries with business rule enforcement
• 🚫 Risk Assessment: Evaluates query safety before execution

Your Role (What You Provide)

• 🤖 AI Service: OpenAI, Anthropic, or your custom AI service
• 🔑 API Keys: Your credentials for the AI service
• 🎛️ Model Selection: Which AI model to use (GPT-4, Claude, etc.)
• 💰 Cost Management: You control your AI service usage and costs

The Integration Flow

1. You ask a question → "Analyze customer retention patterns"
2. SED provides context → Business entities, relationships, security rules
3. SED validates the request → Checks business rules and security policies
4. SED executes the query → Gets data safely from your database
5. Your AI service analyzes → Processes the data and provides insights
6. SED returns everything → Query results + AI analysis + security context

Why This Approach?

• ✅ No vendor lock-in: Use any AI service you prefer
• ✅ Cost control: You manage your AI service costs
• ✅ Security: SED handles data governance, AI handles analysis
• ✅ Flexibility: Switch between AI providers as needed
• ✅ Compliance: Business rules are enforced regardless of AI service

🔒 Security & API Key Management

Best Practices for API Keys

• ✅ Use environment variables - Never hardcode API keys in your code
• ✅ Use .env files - For local development (add .env to .gitignore)
• ✅ Use secret management - For production deployments
• ✅ Rotate keys regularly - Keep your API keys secure

Environment Variable Setup

# Local development (.env file)
echo "OPENAI_API_KEY=your-key-here" > .env
echo "ANTHROPIC_API_KEY=your-key-here" >> .env

# Production (set in your deployment environment)
export OPENAI_API_KEY="your-production-key"
export ANTHROPIC_API_KEY="your-production-key"

What SED Does NOT Do

• ❌ Store API keys - We never see or store your credentials
• ❌ Make external calls - All AI calls go through your environment
• ❌ Track usage - We don't monitor your AI service usage
• ❌ Share data - Your data stays local, AI calls go to your provider

What SED DOES Do

• ✅ Provide security - Business rules, PII protection, access control
• ✅ Validate queries - Ensure AI requests are safe and compliant
• ✅ Manage context - Provide business intelligence and semantic mapping
• ✅ Enforce governance - Apply your company's data policies
