What is the primary purpose of Service Builder in Liferay?

The primary purpose of Service Builder in Liferay is to simplify the creation of services and models. Service Builder is a powerful framework provided by Liferay that allows developers to define the data model and the corresponding services in a straightforward manner, using XML configuration files. This streamlines the development process by automatically generating the necessary Java classes, database schema, and service methods, enabling developers to focus on business logic rather than boilerplate code.

By utilizing Service Builder, developers can easily create, read, update, and delete operations (CRUD) for their entities without manually writing repetitive code. The generated services also adhere to best practices for performance and security, making it easier to maintain and extend applications built on Liferay.

The other choices focus on aspects of application development that are either not directly related to the Service Builder functionality or represent separate capabilities within the Liferay ecosystem, such as managing user roles, enhancing the user interface, or performing database backups, which are managed by different components or tools within Liferay.
