What is "Liferay's Entity Framework" designed to do?

Liferay's Entity Framework is specifically designed to define application entities and their relationships, making it a critical part of Liferay's approach to data modeling. This framework allows developers to create object-oriented representations of data entities, which can include any business model component such as users, products, orders, and more.

By modeling these entities, developers can establish how they interact with each other, which is essential for creating applications that require clear relationships and interactions among different types of data. For instance, an order entity might relate to a user entity, indicating which user made the order, and can be linked to product entities that detail what items were purchased.

The framework also provides mechanisms for CRUD operations (Create, Read, Update, Delete) on these entities and allows for the establishment of entity relationships such as one-to-many, many-to-one, or many-to-many, enhancing the ability to manage complex data structures within applications built on Liferay. This approach helps maintain data integrity, enforce business logic, and ensures the overall maintainability of the application.
