upper/db

upper/db is a Go library that helps application code talk to databases without being tied to any specific one. It works with PostgreSQL, MySQL, Microsoft SQL Server, CockroachDB, MongoDB, SQLite, and a smaller database called QL. Rather than writing raw database queries for each project, developers use upper/db's shared interface and switch the underlying database by changing a single configuration detail. The library is described as a data access layer, which means it sits between the application and the database and handles the translation between Go data structures and database records. It includes features similar to what is often called an ORM (object-relational mapping), a style of database library that lets you work with records as plain objects in code rather than writing query strings manually. This approach can reduce the amount of repetitive database code a team needs to maintain. The README for this project is minimal and points readers to the project website at upper.io/v4 for full documentation and examples. There is also an interactive tour at tour.upper.io where visitors can run live code samples in the browser without installing anything. The library is released under the MIT license, which allows it to be used freely in both personal and commercial projects. This tool is aimed at Go developers who build applications that store and retrieve data from relational or document databases and want a consistent programming interface across those different systems.
