This document outlines the architecture for a student information management system (SIMS) using a layered architecture with Struts as the framework. It describes the services layer, business object layer, and data access object layer. The services layer contains interfaces and implementations for business services. The business object layer contains interfaces and implementations for business objects. The data access object layer contains interfaces and implementations for accessing the database through DAOs. Factories are used to retrieve implementations. Packages are organized with web components in one package and Java components separated into services, business objects, and data access layers.

Services Layer BaseBusinessService <Interface> BusinessService1 <Interface> BusinessService1 <Interface> BusinessService1 <Interface> BusinessService 1Impl BusinessService 1Impl BusinessService 1Impl * Each Interface will cater to a particular functionality . * Will have base attributes, methods each Service to have. Impl would be the implementation of each service We’ll have a Factory Class to get the Implementation Classes for a particular Service. BusinessService Factory Struts Framework Services DAO DB BO Hibernate
Business Object Layer (BO) BaseBusinessObject <Interface/Abstract> BusinessObject1 BusinessObject2 BusinessObject3 * Will have base attributes, methods each BO should have. We’ll have a Factory Class to get the Implementation Classes for a particular Service.(Optional, but good to have based on entity) All the BO’s to implement or derive from an interface BusinessObject Factory Struts Framework Services DAO DB BO Hibernate
Data Access Object (DAO) Layer BaseDAO <Interface/Abstract> DAO1 DAO2 DAO3 * Will have base attributes, methods each BO should have. All the DAO’s to implement or derive from an interface We will have Spring Configure the DAO There would be a DAO for each BO(based on the storage/Data Persistence) DAO would be associated with BO. DAO will have direct JDBC if hibernate is not possible in any scenario. DAO will have basic crud methods. Struts Framework Services DAO DB BO Hibernate
