Choose your input format (CSV, SQL, or JSON), then enter your table structure or select a template. The tool will analyze your table for normalization issues and provide specific suggestions for achieving 1NF, 2NF, and 3NF.
Understanding Database Normalization
Database normalization is the process of organizing data to minimize redundancy and dependency. It helps ensure data integrity and reduces storage space by eliminating duplicate data.
Normalization Forms Explained
- 1NF (First Normal Form): Ensures atomic values, no repeating groups, and unique row identification
- 2NF (Second Normal Form): Meets 1NF and eliminates partial dependencies on composite keys
- 3NF (Third Normal Form): Meets 2NF and eliminates transitive dependencies
Benefits of Proper Normalization
Normalized databases offer better data integrity, reduced storage requirements, easier maintenance, and improved query performance for transactional systems.
Frequently Asked Questions
Q. What format should I use for input?
You can use CSV format with headers, CREATE TABLE SQL statements, or JSON schema format. The tool automatically detects and processes each format.
Q. Does this tool create the normalized tables?
The tool provides analysis and suggestions. You can export the report which includes recommended table structures for implementation.
Q. What about BCNF and higher normal forms?
This tool focuses on 1NF through 3NF, which covers most practical normalization needs. BCNF and 4NF/5NF are for specialized cases.
Q. Can I save my analysis results?
Yes! Use the "Export Report" button to download your analysis results as a text file for future reference.
