## What it is
upper/db is a productive data access layer (DAL) for Go that provides a database-agnostic, ORM-like API for working with SQL and NoSQL databases such as PostgreSQL, MySQL, SQLite, CockroachDB, MSSQL, and MongoDB. It supports CRUD operations, struct-to-query-result mapping, pagination, transactions, and a SQL builder for raw queries.

## Use cases
- query databases in Go without writing raw SQL
- use one consistent API across PostgreSQL, MySQL, and MongoDB
- map Go structs to database query results
- implement pagination for database result sets
- run database transactions from Go code
- mix ORM-style operations with raw SQL queries

## When to choose
- you want ORM-like productivity in Go while retaining the option to write raw SQL
- your application needs to support multiple database backends with a single API
- you need built-in pagination, transactions, and struct mapping

## When to avoid
- you need a full-featured ORM with advanced migrations and associations
- you prefer lightweight direct database drivers like database/sql
- you use a database engine not on the supported list

## Facets
- artifact type: library
- maturity: active
- function: orm, database, database-driver
- domain: databases, backend, web-development
- platform: go, windows, cross-platform
