To draft a complete duombaze.sql (Lithuanian for "database.sql"), a well-structured file should include the core elements for initializing a database: schema creation, table definitions with appropriate data types and constraints, and sample data for testing.
Including common queries can serve as documentation for other developers. You can also use tools like dbForge Documenter to generate comprehensive documentation in HTML or PDF formats.
