How can Liferay objects be defined?

Liferay objects can be defined using the Object Admin application, which is a dedicated interface provided within the Liferay platform. This tool allows developers and administrators to create, manage, and configure custom objects without the need for direct coding or database manipulation. The Object Admin application offers a user-friendly way to define properties, relationships, and behaviors of objects, making it accessible for users who may not be proficient in programming.

With the Object Admin application, you can model various data structures that suit your business needs, streamline workflows, and implement unique functionalities directly within the Liferay environment. This method emphasizes a no-code or low-code approach, speeding up development and ensuring that changes can be made rapidly, which is a core principle of Liferay's flexibility.

In contrast, other choices might involve processes that are either outdated, require programming knowledge, or do not leverage the full capabilities of Liferay’s built-in tools. For instance, using direct database queries may lead to database integrity issues and does not utilize the platform’s comprehensive features for object management. Coding in Java directly is less efficient for creating objects as it lacks the streamlined process that the Object Admin provides. Lastly, while predefined templates can be helpful for quickly setting up certain aspects, they do not offer the same level
