Hello Emad, To answer your question, yes, all entities are not used in actual OFBiz implementations but they are kept there to allow the developers to add custom logic without the need of creating new entities as much as possible. This is the beauty of the data model that is shipped OOTB with OFBiz.
Attribute entities in general data modelling terms are used to define the property of an object or an element. The same is the use of Attribute entity in the OFBiz. So, here, you can define the custom properties/features of the party which cannot be modelled (ethically :)) in other entities, they are put into PartyAttribute entity. You can find Attribute entity in each data model in OFBiz such as OrderAttribute, ProductAttribute, PartyAttribute etc. PartyTypeAttr is used in conjunction with PartyAttribute to restrict PartyAttrubutes for based on partyTypeId. PartyClassification and PartyClassificationGroup entities are mostly used in custom logics to classify the parties in groups. We can take an example of a website which asks the user about the genre of music user likes. We can add PartyClassificationGroups as an individual genre of music and relate the party with the genre they like in PartyClassification entity. Hope this helps.
