 ## Overview
 
 schemachange is a simple python based tool to manage all of your [Snowflake](https://www.snowflake.com/) objects. It follows an Imperative-style approach to Database Change Management (DCM) and was inspired by the [Flyway database migration tool](https://flywaydb.org). When combined with a version control system and a CI/CD tool, database changes can be approved and deployed through a pipeline using modern software delivery practices. As such schemachange plays a critical role in enabling Database (or Data) DevOps.

 The client will be prompted to authenticate in a browser that pops up. Refer to the [documentation](https://docs.snowflake.com/en/user-guide/admin-security-fed-auth-use.html#setting-up-browser-based-sso) to cache the token to minimize the number of times the browser pops up to authenticate the user.
