Babelfish for PostgreSQL accelerates your journey to migrate
SQL Server applications to PostgreSQL
Babelfish for PostgreSQL is an open source project available under the Apache 2.0 and PostgreSQL licenses. It provides the capability for PostgreSQL to understand queries from applications written for Microsoft SQL Server. Babelfish understands the SQL Server wire-protocol and T-SQL, the Microsoft SQL Server query language, so you don’t have to switch database drivers or re-write all of your application queries. With Babelfish, applications currently running on SQL Server can now run directly on PostgreSQL with fewer code changes.
- Great software.
If it doesn’t solve your problems, everything else is moot. It’s going to be software you love to use.
- Open source like we mean it.
We are invested in this being a successful open source project for the long term. It’s all Apache 2.0 and PostgreSQL. There’s no Contributor License Agreement. Easy.
- A level playing field.
We will not tweak the software so that it runs better for any vendor (including AWS) at the expense of others. If this happens, call it out and we will fix it as a community.
- Used everywhere.
Our goal is for as many people as possible to use it in their business, their software, and their projects. Use it however you want. Surprise us!
- Made with your input.
We will ask for public input on direction, requirements, and implementation for any feature we build.
- Open to contributions.
Great open source software is built together, with a diverse community of contributors. If you want to get involved at any level - big, small, or huge - we will find a way to make that happen.
- Respectful, approachable, and friendly.
This will be a community where you will be heard, accepted, and valued, whether you are a new or experienced user or contributor.
- A place to invent.
You will be able to innovate rapidly. This project will have a stable and predictable foundation that is modular, making it easy to extend.
