|
|
|
|
## Context and Problem Statement
|
|
|

JabRef needs to connect to a MySQL database. See [Shared SQL Database](https://docs.jabref.org/collaborative-work/sqldatabase) for more information.
|
|
|
|
## Considered Options
|
|
|
|
* Use MariaDB Connector
|
|
* Use MySQL Connector
|
|
|
|
Other alternatives are listed at [https://stackoverflow.com/a/31312280/873282](https://stackoverflow.com/a/31312280/873282).
|
|
|
|
## Decision Outcome
|
|
|
|
Chosen option: "Use MariaDB Connector", because comes out best \(see below\).
|
|
|
|
## Pros and Cons of the Options
|
|
|
|
### Use MariaDB Connector
|
|
|
|
The [MariaDB Connector](https://mariadb.com/kb/en/library/about-mariadb-connector-j/) is a LGPL-licensed JDBC driver to connect to MySQL and MariaDB.
|
|
|
|
* Good, because can be used as drop-in replacement for MySQL connector
|
|
|
|
### Use MySQL Connector
|
|
|
|
The [MySQL Connector](https://www.mysql.com/de/products/connector/) is distributed by Oracle and licensed under GPL-2. Source: [https://github.com/mysql/mysql-connector-j/blob/release/9.x/LICENSE](https://github.com/mysql/mysql-connector-j/blob/release/9.x/LICENSE). Oracle added the [Universal FOSS Exception, Version 1.0](https://oss.oracle.com/licenses/universal-foss-exception/) to it, which seems to limit the effects of GPL. More information on the FOSS Exception are available at [https://www.mysql.com/de/about/legal/licensing/foss-exception/](https://www.mysql.com/de/about/legal/licensing/foss-exception/).
|
|
|
|
* Good, because it stems from the same development team than MySQL
|
|
* Bad, because the "Universal FOSS Exception" makes licensing more complicated.
