EMS DB Comparer for InterBase/Firebird is a high-performance utility designed to compare and synchronize database structures seamlessly. Developed by EMS Software Development, it allows developers and database administrators to instantly identify schema discrepancies and automatically generate SQL scripts to align different database environments. Key Features
Schema & Object Comparison: Analyzes all or selected database structures, including tables, views, triggers, indexes, and stored procedures.
Automated Script Generation: Produces precise modification scripts to deploy schema changes from a source to a target database.
Step-by-Step Execution: Offers a visual interface to manually review structural differences before synchronization, alongside fully automated operations.
Console Application: Supports a powerful command-line interface to automate routine comparison and sync tasks via scheduled scripts.
Project Management: Enables users to configure, save, and manage multiple database comparison projects simultaneously.
Detailed Reporting: Generates comprehensive difference reports that can be printed or exported. How It Works
Target Selection: Users define a reference (source) database and a target database that needs to be updated.
Analysis: The engine parses both environments to group components into matching structures, source-only objects, and target-only objects.
Review: The graphical interface uses visual cues to pinpoint specific structural differences, such as missing columns or altered data types.
Resolution: The tool generates a deployment script to cleanly update the target structure without losing structural integrity. Core Comparison
While DB Comparer focuses purely on database metadata (the architecture), it is often paired with a sister application for moving the actual data rows: DB Comparer for InterBase/Firebird – EMS SQL Manager
