Liferay service builder is basically used to create the service layers for any business logic implementation. From DEVELOPER point of view it is very helpfull as it used to create all the service layers automatic. Suppose we want to develop a portlet, for this we need to write all the required implementation CLASSES, utility cleasses and other required classes. Service builder is used to create all these classes for developer, where they can ADD their business logic further and process the data and render the output to view as per the requirement. 

As per the advantage, this service builder will create whole structure of the service layers for developer MAINLY. It REALLY helps them to write the code and their logic in service builder created model implementations and service implementation classes. These classes comes with normal CRUD (create, update and delete)operations. For developer, no need to add anything extra as whole service and utility layers are already got created by service builder. It really speed up the developement process.

Service builder requires service.xml which is having some of the required entries. Each of the entry is basically called entity, which is having it's primary key fields with some other required fields. If we want to implement order and finder method, we can implement it by using this service.xml. 

Each entity creates table into liferay configured database with the given column names and their types. We can create service.xml related local-service and remote-service by setting them value as "true". When we would run this build-service like below, this would create all the service layers(implementation, utility etc.) where developer can write their required business logic further. Creation of all the service-classes would be done by the build.xml, we need to build-services using this xml file into Ant view of IDE.
