Leveraging AI Assistant for Common Data Tasks

This guide shows you how to leverage Coginiti's AI Assistant for key data analysis tasks including code analysis, CoginitiScript generation, test writing, and platform optimization. Learn practical techniques for getting the most out of AI-powered assistance in your daily data work.

Prerequisites

Before using these AI Assistant capabilities, ensure you have:

• AI Assistant configured in your Coginiti instance (see How to Configure AI Assistant)
• Basic familiarity with SQL and CoginitiScript
• Access to a database connection for testing generated code
• Understanding of your data schema for context-aware assistance

Overview

The AI Assistant provides specialized capabilities for data professionals, understanding database schemas, existing code patterns, and analytical objectives. This guide covers four key areas where AI assistance can dramatically improve your productivity and code quality.

Core Use Cases

1. Analyze Code Base

The AI Assistant can comprehensively analyze your existing code base to provide insights, identify patterns, and suggest improvements.

Code Understanding and Documentation

• Legacy Code Analysis: Understand complex queries and scripts written by others
• Code Documentation: Generate explanations for undocumented database procedures
• Logic Flow Analysis: Break down complex analytical workflows into understandable steps
• Dependency Mapping: Identify relationships between queries, tables, and data flows

Quality Assessment

• Performance Analysis: Identify potential performance bottlenecks in existing queries
• Best Practice Review: Compare code against SQL and CoginitiScript best practices
• Security Review: Identify potential security vulnerabilities or unsafe patterns
• Maintainability Assessment: Evaluate code complexity and suggest refactoring opportunities

Pattern Recognition

• Common Patterns: Identify recurring analytical patterns across your code base
• Optimization Opportunities: Spot repeated logic that could be modularized
• Inconsistency Detection: Find variations in naming conventions or coding styles
• Reusability Analysis: Identify code segments that could be converted to reusable components

Example Workflow:

-- AI Assistant analyzes this complex query
WITH revenue_analysis AS (
  SELECT customer_id, 
         SUM(order_total) as total_revenue,
         COUNT(*) as order_count,
         AVG(order_total) as avg_order_value
  FROM orders 
  WHERE order_date >= '2023-01-01'
  GROUP BY customer_id
),
customer_segments AS (
  SELECT *,
         CASE 
           WHEN total_revenue > 10000 THEN 'High Value'
           WHEN total_revenue > 1000 THEN 'Medium Value'
           ELSE 'Low Value'
         END as segment
  FROM revenue_analysis
)
SELECT segment, 
       COUNT(*) as customer_count,
       AVG(total_revenue) as avg_revenue_per_segment
FROM customer_segments
GROUP BY segment;

-- AI provides analysis:
-- "This query performs customer segmentation analysis using RFM methodology.
-- Performance optimization: Consider indexing order_date and customer_id.
-- Pattern detected: This segmentation logic appears in 3 other queries - 
-- consider creating a reusable CoginitiScript block."

2. Generate CoginitiScript Code

Advanced CoginitiScript Features

• Dynamic SQL Generation: Create adaptive queries based on runtime conditions
• Environment Management: Generate code that works across development, staging, and production
• Error Handling: Implement robust error handling and logging patterns
• Performance Optimization: Generate code optimized for specific database platforms

Business Logic Implementation

• Complex Calculations: Implement sophisticated business rules and calculations
• Data Validation: Create comprehensive data quality checks and validations
• Transformation Logic: Build complex ETL processes with proper error handling
• Reporting Automation: Generate code for automated report generation

Example Generation:

-- AI generates this CoginitiScript block from prompt:
-- "Create a customer lifetime value calculation with configurable time periods"

block CustomerLTV(
    start_date date,
    end_date date,
    customer_segment string = 'all'
) -> table {
  
    select 
        c.customer_id,
        c.customer_name,
        c.segment,
        sum(o.order_total) as total_revenue,
        count(distinct o.order_id) as total_orders,
        avg(o.order_total) as avg_order_value,
        max(o.order_date) as last_order_date,
        datediff('day', min(o.order_date), max(o.order_date)) as customer_lifespan_days,
        case 
            when datediff('day', min(o.order_date), max(o.order_date)) > 0 
            then sum(o.order_total) / datediff('day', min(o.order_date), max(o.order_date)) * 365
            else sum(o.order_total)
        end as estimated_annual_ltv
    from 
        customers c
        join orders o on c.customer_id = o.customer_id
    where 
        o.order_date between {{start_date}} and {{end_date}}
        and ({{customer_segment}} = 'all' or c.segment = {{customer_segment}})
    group by 
        c.customer_id, c.customer_name, c.segment
    having 
        count(distinct o.order_id) >= 2  -- Only customers with repeat purchases
    order by 
        estimated_annual_ltv desc;
}

    setup {
        create temp table test_customers (
            customer_id int,
            customer_name varchar(100),
            segment varchar(50)
        );
  
        create temp table test_orders (
            order_id int,
            customer_id int,
            order_date date,
            order_total decimal(10,2)
        );
  
        -- Insert test data
        insert into test_customers values 
            (1, 'Test Customer 1', 'Premium'),
            (2, 'Test Customer 2', 'Standard');
      
        insert into test_orders values
            (1, 1, '2023-01-01', 100.00),
            (2, 1, '2023-06-01', 150.00),
            (3, 2, '2023-02-01', 75.00),
            (4, 2, '2023-08-01', 125.00);
    }
  
    -- Execute the block
    result = CustomerLTV('2023-01-01', '2023-12-31', 'all');
  
    -- Assertions
    assert.rowCount(result, 2);
    assert.columnExists(result, 'estimated_annual_ltv');
    assert.greaterThan(result.where(customer_id = 1).estimated_annual_ltv, 0);
  
    cleanup {
        drop table test_customers;
        drop table test_orders;
    }
}

test "CustomerLTV_EdgeCases" {
    -- Test edge cases like single orders, zero amounts, etc.
    setup {
        -- Edge case test data setup
    }
  
    result = CustomerLTV('2023-01-01', '2023-12-31', 'all');
  
    -- Edge case assertions
    assert.noNullValues(result, 'estimated_annual_ltv');
    assert.noNegativeValues(result, 'total_revenue');
}

4. Platform Optimizations

The AI Assistant provides intelligent recommendations for optimizing performance across different database platforms and deployment scenarios.

Database-Specific Optimization

• Query Optimization: Generate platform-specific optimized queries for PostgreSQL, SQL Server, MySQL, etc.

Example Optimization:

-- Original query
SELECT c.customer_name, SUM(o.order_total) as total_revenue
FROM customers c
JOIN orders o ON c.customer_id = o.customer_id
WHERE o.order_date >= '2023-01-01'
GROUP BY c.customer_name
ORDER BY total_revenue DESC;

-- AI Assistant optimized version with explanations:
-- Optimization 1: Add index hint for better performance
-- Optimization 2: Use window functions to avoid sorting large result sets
-- Optimization 3: Add execution plan analysis

WITH customer_revenue AS (
  SELECT 
    c.customer_id,
    c.customer_name,
    SUM(o.order_total) as total_revenue,
    -- Add ranking for efficient top-N queries
    ROW_NUMBER() OVER (ORDER BY SUM(o.order_total) DESC) as revenue_rank
  FROM customers c
  JOIN orders o ON c.customer_id = o.customer_id
  WHERE o.order_date >= '2023-01-01'
    AND o.order_total > 0  -- Filter out zero/negative orders early
  GROUP BY c.customer_id, c.customer_name
)
SELECT customer_name, total_revenue
FROM customer_revenue
WHERE revenue_rank <= 1000  -- Limit result set for better performance
ORDER BY revenue_rank;

-- Suggested indexes:
-- CREATE INDEX idx_orders_date_customer_total ON orders(order_date, customer_id, order_total);
-- CREATE INDEX idx_customers_id_name ON customers(customer_id, customer_name);
