--- title: Database Support category: Getting Started chapter: 1 order: 6 --- Dependency-Track includes an embedded H2 database enabled by default. The intended purpose of this database is for quick evaluation, testing, and demonstration of the platform and its capabilities. > The embedded H2 database is not intended for production use. Dependency-Track supports the following database servers: * Microsoft SQL Server 2012 and higher * MySQL 5.6 and higher * PostgreSQL 9.0 and higher To change database settings, edit `application.properties` found in the Dependency-Track data directory. #### Microsoft SQL Server Example ```ini alpine.database.mode=external alpine.database.url=jdbc:sqlserver://localhost:1433;databaseName=dtrack alpine.database.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver alpine.database.driver.path=~/path/to/sqljdbc4.jar alpine.database.username=dtrack alpine.database.password=password ``` #### MySQL Example ```ini alpine.database.mode=external alpine.database.url=jdbc:mysql://localhost:3306/dtrack?autoReconnect=true&useSSL=false alpine.database.driver=com.mysql.jdbc.Driver alpine.database.driver.path=~/path/to/mysql-connector-java-5.1.45-bin.jar alpine.database.username=dtrack alpine.database.password=password ``` For MySQL, it is necessary to remove 'NO_ZERO_IN_DATE' and 'NO_ZERO_DATE' from the sql-mode prior to creating the Dependency-Track database. It's also necessary to add 'ANSI_QUOTES' to the sql-mode. Refer to the MySQL documentation for details. There are several ways to change this configuration, however the recommended way is to modify the MySQL configuration (typically my.ini or similar) with the following: ```ini [mysqld] sql_mode="ANSI_QUOTES,STRICT_TRANS_TABLES,ONLY_FULL_GROUP_BY,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" ``` #### PostgreSQL Example ```ini alpine.database.mode=external alpine.database.url=jdbc:postgresql://localhost:5432/dtrack alpine.database.driver=org.postgresql.Driver alpine.database.driver.path=~/path/to/postgresql-42.2.1.jar alpine.database.username=dtrack alpine.database.password=password ```
