What type of database does Liferay support?

Liferay provides support for multiple database systems, making it versatile for different development and production environments. By being compatible with various databases, such as MySQL, Oracle, PostgreSQL, and SQL Server, Liferay allows developers to choose a database that suits their needs and preferences.

This flexibility is important as organizations may already have established databases or may prefer a particular database for reasons such as scalability, cost, or specific feature sets. Additionally, supporting multiple databases helps facilitate better integration and migration options for user data and applications, ultimately enhancing the platform's usability and adaptability in various scenarios.

The other choices are limited in scope, focusing on single options rather than acknowledging the broader compatibility that Liferay offers. This makes the correct answer particularly valuable to users looking to leverage Liferay within diverse technological environments.
