SSA Global is a global solutions provider in enterprise business software (automotive, manufacturing, and distribution), customer relationship management, product lifecycle management, business intelligence, supply chain management, and supplier relationship management. The company offers unparalleled application breadth, market experience, open technology, and global reach.
Project Objective:Develop a Java-based integration application that bridged two ERP systems and facilitated exchange of data between them. Business functions such as Demand or Inventory Planning, Manufacturing or Warehouse Management were the primary targets of integration.
The project applied a J2EE pattern of Data Access Object (DAO) to abstract and encapsulate all access to the data sources residing on IBM iSeries (AS400) computers. The DAO managed the connection with the data source to obtain and store the data. SSA ERP LX, PRMS, Logility Voyager are examples of the ERP systems being integrated.
Primary Responsibilities: Defined architecture of the integration using UML Component, Class, and Communication diagrams and sought the approval of the concept from the users.
Prepared a detailed design for the application using UML Use Case and Sequence diagrams.
Created DAO BusinessObjects, which represented the data Client. These simple Java objects required access to the data source to obtain and store the data.
Implemented DAO DataAccessObjects. The DAO objects abstracted the underlying data access implementation for the BusinessObjects to enable transparent access to the data source. The DAO implemented the access mechanism required to work with the data source.
Defined DAO DataSources. The sources of data were the DB400 tables residing on IBM iSeries systems.
Implemented DAO TransferObjects. These objects carried the data. The DataAccessObjects used Transfer Objects to return data to the client or to receive data from the client in order to update data in the data source.
Designed the application as highly configurable by implementing Java Properties files and XML configuration files.
Used Eclipse and IBM Rational Development Platform to create Java and ILE RPG programs.
Used DOM API for parsing and formatting XML documents.
Applied the JDBC API to access and to manipulate data in persistent storage, such as a relational database on the IBM iSeries system.
Used IBM WebSphere 5.1 as an application server for the integration modules.
Modified ILE RPG programs on AS400 to meet requirements of the integration.
Environment: Java SE 1.4, J2EE, Servlets/JSP, JSTL, EL, Eclipse 3.1, XML, XSD, XSL, JDBC, DAO, JNDI, SQL, Windows 2000/XP, UML, HTML, IBM WebSphere 5.1, IBM iSeries, ILE RPG, and DB400.

Primary Responsibilities: Developed use case scenario, class and deployment diagrams for the application.
Aided in database (Oracle, SQL Server, and DB2) structuring and creation.
Developed Action forms, Action Classes using Struts Framework to handle user requests.
Used Struts to develop Servlet Action Classes and Form Beans for the different actions. Coded the Action classes to provide an interface to the application's Model layer incorporating business logic.
Coded ActionForm of the application of JavaBeans that encapsulated and validated request parameters. These ActionForms served as a carrier of request data to the Action class.
Coded a JSP object combining with a respective ActionForm to form the application's View layer, where almost every form field of the JSP object mapped to an attribute of the corresponding ActionForm.
Used JSP custom tag libraries in conjunction with HTML, logic, and bean tags; this aided with the minimal maintenance required for JSP pages.
Used ActionErrors to support exception handling, to trap and propagate an application exception to the View layer.
Used JavaScript for client side validations of the data.
Environment: Java SDK, J2EE, Servlets/JSP, Swing, Eclipse 3.1, XML, XSD, XSL, Oracle, JNDI, SQL, Windows XP/2000, UML, HTML, JavaScript, and CSS.
