Frequently Asked Questions About Database Tools

Yes. It analyzes values in each column to detect integers, floating point numbers, dates, booleans, and string lengths, creating optimized VARCHAR or INT data types.

Generated queries follow standard ANSI SQL compatible with MySQL, PostgreSQL, MariaDB, SQLite, and Microsoft SQL Server.

It calculates how many tree levels and disk I/O reads are required to locate a row based on your key size, block/page size (e.g. 16KB for InnoDB), and total table record count.
