## What it is
The Microsoft JDBC Driver for SQL Server is a Type 4 JDBC driver providing database connectivity to SQL Server and Azure SQL Database from Java applications via the standard JDBC API. It is distributed on Maven Central with builds for Java 8 and Java 11+.

## Use cases
- connect a Java application to SQL Server
- connect Java apps to Azure SQL Database
- use SQL Server from a Java application server
- run JDBC queries against SQL Server from any Java-enabled applet
- add mssql-jdbc as a Maven dependency for database access

## When to choose
- your Java or JVM application needs to talk to Microsoft SQL Server or Azure SQL Database
- you want the official, Microsoft-supported JDBC driver
- you need a pure-Java Type 4 driver with no native dependencies

## When to avoid
- you are connecting to non-Microsoft databases like PostgreSQL or MySQL
- your stack is not on the JVM
- you need a driver for a different database protocol

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, database
- domain: databases, backend, developer-tools
- platform: jvm, cross-platform
- tags: jdbc, sql-server, azure-sql, type-4-driver, maven
