Database Analysis Tool: AI-Powered Database Insights

Write Your First SQL Query in 10 Seconds—Free

Analyze Your Database Structure and Performance

Instantly analyze your database to uncover performance bottlenecks, optimization opportunities, and structural improvements with our AI-powered analysis tool.

Key Features

1. Schema Analysis

— Example analysis output Table: customers ├── Columns: 12 ├── Indexes: 3 ├── Foreign Keys: 2 └── Recommendations: ├── Add index on (last_login, status) ├── Optimize data types for email, phone └── Consider partitioning by

2. Performance Metrics

— Query performance analysis SELECT table_name, avg_row_length, data_length/1024/1024 as size_mb, index_length/1024/1024 as index_size_mb, table_rows FROM information_schema.tables WHERE table_schema = DATABASE() ORDER BY data_length DESC;

— Recommendations: — 1. Optimize large tables — 2. Review index usage — 3. Consider partitioning

3. Query Analysis

— Slow query identification SELECT query_time, rows_examined, rows_sent, sql_text FROM mysql.slow_log WHERE start_time > DATE_SUB(NOW(), INTERVAL 24 HOUR) ORDER BY query_time DESC LIMIT 10;

— AI-Generated Optimization: — 1. Add covering indexes — 2. Rewrite subqueries — 3. Optimize JOIN order

Analysis Types

1. Structure Analysis

  • Table relationships

  • Index coverage

  • Data type optimization

  • Constraint validation

  • Normalization check

2. Performance Analysis

  • Query execution plans

  • Index usage statistics

  • Buffer pool utilization

  • Cache hit rates

  • I/O patterns

3. Data Quality Analysis

  • Null value patterns

  • Data distribution

  • Cardinality analysis

  • Redundancy check

  • Consistency validation

Real-World Applications

1. E-commerce Database

— Analysis findings Tables requiring attention:

  1. products

    • High update frequency
    • Missing index on (category_id, price)
    • Consider partitioning by date

  2. orders

    • Large table (500GB)
    • Suboptimal JOIN

2. User Analytics System

— Performance bottlenecks

  1. user_events table
    • High write volume
    • Inefficient indexes
    • Recommend: └── Partitioning by

Optimization Recommendations

1. Index Optimization

— Current indexes SHOW INDEX FROM orders;

— Recommended new indexes CREATE INDEX idx_order_status ON orders(status, created_at); CREATE INDEX idx_product_category ON products(category_id, status)

2. Query Optimization

— Before optimization SELECT c.customer_name, COUNT(o.order_id) as total_orders FROM customers c LEFT JOIN orders o ON c.id = o.customer_id WHERE o.created_at >= DATE_SUB(NOW(), INTERVAL 30 DAY) GROUP BY c.id, c.customer_name;

— After optimization SELECT c.customer_name, COUNT(o.order_id) as total_orders FROM customers c LEFT JOIN orders o ON c.id = o.customer_id AND o.created_at >= DATE_SUB(NOW(), INTERVAL 30 DAY) GROUP BY c.id,
