A modern, enterprise-ready database system with hierarchical schemas and enhanced utilities
ScratchBird is a revolutionary database system that extends proven Firebird technology with modern features that exceed even PostgreSQL's capabilities. Built from Firebird 6.0.0.929, ScratchBird introduces hierarchical schemas, enhanced utilities, and enterprise-grade features while maintaining 100% compatibility with existing Firebird applications.
🌳 Revolutionary Hierarchical Schemas: Create nested schemas up to 8 levels deep with syntax like company.finance.accounting.reports - exceeding PostgreSQL's flat schema limitations.
🛠️ 11 Enhanced Utilities: Complete suite of modernized database tools with parallel processing, compression, encryption, and intelligent automation.
📚 Enterprise Documentation: Comprehensive documentation system designed to guide users from novice to expert level.
🔧 Production Ready: Fully tested, cross-platform compatible, with automated installation and enterprise deployment support.

# Expected: sb_isql version SB-T0.5.0.1 ScratchBird 0.5 f90eae0-- Connect and create database with hierarchical schemas
sb_isql -user SYSDBA -password masterkey
SQL> CREATE DATABASE 'myapp.fdb' USER 'SYSDBA' PASSWORD 'masterkey';
SQL> CONNECT 'myapp.fdb' USER 'SYSDBA' PASSWORD 'masterkey';
-- Create hierarchical schema structure (exceeds PostgreSQL!)
SQL> CREATE SCHEMA company;
SQL> CREATE SCHEMA company.finance;
SQL> CREATE SCHEMA company.finance.accounting;
SQL> CREATE SCHEMA company.finance.accounting.reports;
-- Set working schema and create tables
SQL> SET SCHEMA 'company.finance.accounting';
SQL> CREATE TABLE transactions (
CON> id INTEGER PRIMARY KEY,
CON> amount DECIMAL(15,2),
CON> description VARCHAR(200),
CON> created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
CON> );
SQL> INSERT INTO transactions (id, amount, description)
CON> VALUES (1, 1000.50, 'Initial deposit');
SQL> SELECT * FROM transactions;
SQL> SHOW SCHEMAS; -- See your hierarchical structure# Advanced backup with compression and validation
sb_gbak -backup -compress -validate-on-create -user SYSDBA myapp.fdb myapp_backup.fbk
# Database analysis with recommendations
sb_gstat -analyze -recommendations -format html -output analysis.html myapp.fdb
# Real-time monitoring dashboard
sb_gstat -monitor -web-interface 8080 myapp.fdb
# Open http://localhost:8080 in your browser
# Database health check and repair
sb_gfix -health-check -comprehensive -recommendations myapp.fdb-- Create nested organization structure
CREATE SCHEMA company.divisions.engineering.teams.backend.services.authentication;
-- Work naturally with nested schemas
SET SCHEMA 'company.divisions.engineering';
CREATE TABLE projects (id INTEGER, name VARCHAR(100));
-- Reference across hierarchy
SELECT p.name, u.username
FROM teams.backend.projects p
JOIN ../../hr.employees.users u ON p.owner_id = u.id;Benefits over PostgreSQL:
- ✅ 8-level nesting vs PostgreSQL's flat schemas
- ✅ Relative path navigation with
../parentsyntax - ✅ Inheritance permissions down the hierarchy
- ✅ Schema-aware operations in all utilities
