Andrew Hart

Andrew Hart is a staff software engineer at the NASA Jet Propulsion Laboratory (JPL) where he works in the Data Management Systems and Technologies group. He brings his computer science background and creative talents to the design and development of data management components and web interfaces for a wide range of projects including an informatics infrastructure for the National Cancer Institute’s Early Detection Research Network (EDRN), data modeling and architectural support for the Laura P. and Leland K. Whittier Virtual Pediatric Intensive Care Unit (Whittier VPICU) at Children’s Hospital Los Angeles, and web services for JPL's Regional Climate Model Evaluation System. He is also an active contributor to the Object Oriented Data Technology (OODT) project which last year became a TLP at Apache.

Using OODT to Support Data-driven Clinical Decision Support
November 9 4:00PM
OODT traces its roots to planetary and Earth science data systems to support research at the NASA Jet Propulsion Laboratory. Today, as an open-source project at Apache, OODT has a thriving and diverse community that includes projects in Cancer Research, Radio Astronomy, Pediatric Care, Computer Modeling, and Visualization. This session will discuss how many of the components of OODT have been used in concert to develop end-to-end data analysis infrastructures for examining large volumes of complex medical data. Motivated by, and illustrated with, concrete examples from our experience developing an infrastructure for data-driven decision support at the Whittier Virtual Pediatric Intensive Care Unit at Childrens Hospital Los Angeles.

Topics include:

- How the OODT Product Server component can be used to bring together data from multiple upstream sources
- How the OODT File Manager component can be used to manage scalable collections of data + metadata
- How the OODT Workflow Manager component helps build composable workflows for de-identification, aggregation, and analysis
- How the OODT Web-Grid and web services can help to distribute research data to both users and applications
- How OODT Balance can help in developing purpose-built interfaces for data discovery and visualization

Introduction to the OODT Process Control System Operator's User Interface (OpsUI)
November 9 1:30PM
One of OODT's core strengths is the loosely connected nature of its components. This architecture allows data management infrastructures to be composed by linking the core building blocks together in various ways to support a broad spectrum of data system requirements.

Three of the core OODT components, the File Manager, Workflow Manager, and Resource Manager, along with components for crawling data repositories and extracting metadata, together represent the fundamental ingredients of many large-scale data system projects and are often referred to as a Process Control System or PCS. This session will discuss a new, unified "operator" interface for monitoring and interacting with the Process Control System.

The OODT PCS Operator User Interface, or OpsUI, provides high-level and detailed information about the status of the underlying components in an intuitive, browser-based interface. It takes advantage of a suite of RESTful web services developed in OODT 0.3 that expose component level information as JSON.

This session will provide an overview of the OpsUI, discuss the services it provides, and explain how the interface can be used to monitor and manage a full-scale data system in real time.
