Case Study: SRM 2.0 - A next generation shared resource management system built on SpringSource dm Server - By Matt Stine - October 19 - 22, 2009

St. Jude Children's Research Hospital's Shared Resource Management (SRM) system is a laboratory management system designed to support core facility activities. It was originally designed to support the laboratories in the Hartwell Center for Bioinformatics and Biotechnology (http://www.hartwellcenter.org) at St. Jude, and was implemented over the course of 3 years using a traditional J2EE stovepipe architecture leveraging EJB 2.0 and a "homegrown" web framework. Fast-forward five years to 2009, and you'll find SRM 2.0, a complete rewrite using Spring, Spring Web MVC, Spring DM/OSGi, and SpringSource dm Server, nearing a production release after approximately nine months of effort.

Topics covered will include:

A brief overview of St. Jude and the SRM domain.

SRM 1.x: - Architecture - Development Process - Domain Model - Technology Stack - Issues

The crossroads that led to the development of SRM 2.0.

SRM 2.0 and the SRM Data Bus: - Architecture - Demos

How Spring Dynamic Modules and dm Server enabled: - effective modularization of system responsibilities - strict enforcement of module boundaries - isolation of risk, change, technology, dependencies, and developer responsibility - an innovative plug-in architecture allowing functional extension of the system without modification to the core platform
