Entity Framework Migration Tools

The Microsoft Entity Framework Migrations tools are a publicly available API that Microsoft provides for .NET C# projects, but more specifically .NET CORE server projects. These tools allow a developer to write C# class files for each table that is to be created, add properties to each class that correspond to the columns for each table, and then have the software automatically generate an SQL script file. This script file can then be used along with our Liquibase implementation to more securely add/remove/modify the Cloud database.

Liquibase

Liquibase is a database management tool that allows developers to automate database updates and migrations. The software lies within the project, and provides command line control over updating the database. When issues arise, the software has automatic rollbacks, so there is no risk of losing live data.

Postman

Postman is a software tool that allows developers to locally test API interactions without needing to use the browser. It provides the ability to easily create a request body in multiple data formats (JSON, plain text, etc.) as well as request headers. This software expedites the process of creating and testing new API endpoints.
