SQLbundin

SQLbundin is a software tool and workflow designed to package, version, and deploy SQL scripts as cohesive units. It allows grouping multiple SQL statements, migrations, and related tasks into bundles that can be stored, tested, and applied consistently across databases and environments. The approach aims to improve reproducibility, auditing, and governance of database changes.

A bundle consists of a descriptor file, a collection of scripts, and metadata such as dependencies and parameters. The execution engine resolves ordering, validates scripts, and runs them within defined transactional boundaries. Bundling supports parameterization so that the same bundle can be deployed to different environments with environment-specific values.

Architecture typically includes a core engine, a bundle repository or directory, adapters for target databases (for example, PostgreSQL, MySQL, SQL Server), and a user interface such as a command-line interface or software development kit. Workflows involve creating a descriptor, adding scripts with dependencies, running tests, and applying changes to target systems with logs and rollback support.

Example usage may specify a descriptor that lists scripts in order: create_table.sql, insert_seed.sql, and add_indexes.sql, with parameters for schema and environment. The engine executes in a defined context, producing an execution log and a migration record.

Advantages include reproducible deployments, centralized change governance, and an auditable history. Limitations include the need for disciplined change management, potential vendor-specific behavior, and the learning curve for teams accustomed to other migration approaches. It is complementary to, rather than a replacement for, general database migrations frameworks.
