To provide migration of two modules of an outpatient hospital management system to the J2EE platform and development of additional modules.
Artezio transitioned the entire solution to the J2EE platform and added some missing features. Java Server Pages replaced the ASP code.
The Microsoft SQL Server database was migrated to an Oracle 9i database.
For clear business logic, the Model View Controller architecture was employed with a presentation layer implemented with JSP and JSTL technologies, a controller layer based upon Struts controller servlets and actions, and a model layer relying on Hibernate – an object/relational persistence and query service for Java.
In the development environment, Apache Jakarta Tomcat open source servlet container was used; however, in the testing and production environments, Oracle 9i Application Server was the Customer’s choice.
The system featured flexible security policy regulating user access to data and functions for various categories of users.
The system has an extensive audit trail capability where all changes to the database records can be viewed by a user with a special status.
The system features dozens of reports that may be conveniently viewed and printed from a pop-up web browser window.
The user interface was designed easy to customize for non-programmer system administrators.
After completing the migration phase, the system’s performance and functionality was tested internally by the Artezio testing department and then the system was deployed.
