## What it is
MySQL Connector/J is the official pure-Java JDBC driver for MySQL, implementing the JDBC 4.2 API and the MySQL X DevAPI for NoSQL-style document store operations. It connects Java applications to MySQL servers without requiring native MySQL client libraries.

## Use cases
- connect a Java application to a MySQL database
- run SQL queries from Java via JDBC
- use MySQL as a document store with NoSQL CRUD operations
- configure a MySQL datasource for a Spring or Jakarta EE app
- migrate an old MySQL Java driver to the current connector

## When to choose
- your Java or JVM application needs to talk to MySQL
- you want a pure-Java driver with no native dependencies
- you need X DevAPI document-store access to MySQL

## When to avoid
- you use PostgreSQL, SQL Server, or another non-MySQL database
- you need a driver for a non-JVM language
- GPLv2 licensing with FOSS exception is incompatible with your project

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, database
- domain: databases, backend, developer-tools
- platform: jvm, cross-platform
- tags: jdbc, mysql, x-devapi, document-store, sql
