Your data never leaves your environment. Direct SQL execution keeps everything secure and compliant.

🚀 Real-World Power in Action

💼 Executive Dashboard Query

Question: "What's our revenue growth by product category compared to last quarter?"

🏆 PeopleWorks GPT (Direct SQL) Response:

SELECT 
    pc.CategoryName,
    SUM(CASE WHEN s.Date >= '2024-07-01' THEN s.Amount ELSE 0 END) as CurrentQ,
    SUM(CASE WHEN s.Date >= '2024-04-01' AND s.Date < '2024-07-01' THEN s.Amount ELSE 0 END) as LastQ,
    ROUND(
        (SUM(CASE WHEN s.Date >= '2024-07-01' THEN s.Amount ELSE 0 END) - 
         SUM(CASE WHEN s.Date >= '2024-04-01' AND s.Date < '2024-07-01' THEN s.Amount ELSE 0 END)) 
        / SUM(CASE WHEN s.Date >= '2024-04-01' AND s.Date < '2024-07-01' THEN s.Amount ELSE 0 END) * 100, 2
    ) as GrowthPercent
FROM Sales s
JOIN Products p ON s.ProductID = p.ProductID  
JOIN ProductCategories pc ON p.CategoryID = pc.CategoryID
WHERE s.Date >= '2024-04-01'
GROUP BY pc.CategoryName
ORDER BY GrowthPercent DESC;
            

⏱️ Execution Time: 23 milliseconds | ✅ 100% Accurate Results

❌ Embeddings Approach Struggle:

Step 1: Convert question to vector embeddings... 🕐

Step 2: Search through pre-computed document embeddings... 🕑

Step 3: Find "similar" content about revenue and categories... 🕒

Step 4: Hope the retrieved content has the right data... 🕓

Step 5: Generate approximate answer from retrieved text... 🕔

⏱️ Total Time: 3-15 seconds | ❓ Results may be outdated or approximated

💡 Why We Believe 100% in Direct SQL

🎯

Mathematical Precision

SQL is mathematics. When you ask for "revenue growth," you get exact calculations, not similarity approximations.

🏗️

Database DNA

Databases were designed for queries. Why fight their nature? We embrace and amplify their natural strength.

⚡

Speed of Light

Direct execution means database-speed results. Your enterprise database can handle millions of rows in milliseconds.

🔐

Security by Design

No data copying, no external processing. Your data stays where it belongs - in your secure database.

🔍

Complete Transparency

Every query is visible, debuggable, and optimizable. No black boxes, no mystery algorithms.

📈

Infinite Scalability

Your database scales, we scale. No additional infrastructure, no embedding storage limits.

🔥 The Revolutionary Insight

While the industry chases complex embeddings and vector databases, we realized the truth: The best way to query a database is to ACTUALLY QUERY THE DATABASE! Revolutionary? Maybe. Obvious in hindsight? Absolutely!
