Technical Strategies

System Overview

Architectural View of the Application – ECMS requirements shall map on a logical multitier architecture. Division between the logical tiers

Technological Approach Model View Controller architecture (MVC)- We are adopting the well known and proven MVC architecture for the application design and development. MVC architecture shall be achieved using Struts 2 as a Web Tier base line framework. Together with the above mentioned approach following are the applicable J2EE design patterns identified – Business Delegate Service Locator Front Controller Data Access Object Value Object Interceptors. Session Facade View  Renders the Model.  Send user requests to controller. View  Renders the Model.  Send user requests to controller. Model  Encapsulate application states.  Maintained by Controller and refer by View. Model  Encapsulate application states.  Maintained by Controller and refer by View. Controller  Selects view for response.  Updates Model with user actions. Controller  Selects view for response.  Updates Model with user actions. Changes the State Query the state Select the view

Design Aspects WEB – centric design (Web tier to communicate with Database) EJB – centric design (EJB tier to communicate with Database) Both of mentioned design approaches have their own benefits and down sides, however, for ECMS requirements point of view we have decided to go with EJB- centric design by keeping following things in mind Robustness. Secure access to the software components. Reusability. Managed transactions. Focus development on application domain. Proven container provided Transaction Management. More manageable large scale data intensive systems.

Platform and Software Components The development platform shall be Java EE 6, which has many APIs. However, for the requirement of ECMS, we are going to explore mainly followings Java Platform, Enterprise Edition 6 (Java EE 6) Enterprise JavaBeans 3.1 Java Servlet 3.0 JavaServer Pages 2.2/Expression Language 2.2 Standard Tag Library for JavaServer Pages (JSTL) 1.2 Followings are the Third Party Open Source Components to be integrate Apache log4j 1.2 APIs (For logging purpose) Hibernate (For Object Relational Mapping) Struts 2 (Web Tier framework to stick with MVC) Jasper Reports (For Reporting)
