Introduction to
Data Management
Motivation
What is the system and model to solve these problems in an automated way?
Motivation
A Definition of Data Management
"The development, execution and supervision of plans, policies, programs and practices that control, protect, deliver and enhance the value of data and information assets."
Organizations need a future-proof solution to managing data and its surrounding infrastructure.
What is iRODS
iRODS is
A flexible framework for the abstraction of infrastructure
iRODS as the Integration Layer
Creating the Machine
What are the necessary component to build such a system?
iRODS Architecture
iRODS is ultimately a Catalog and an RPC API
Catalog Service Consumers
Servers which provide access to storage resources
Catalog Service Provider
Same capabilities as the Consumer with the addition of a database plugin
Metadata Catalog
What are some limitations of this design?
Limitations of System Design
Addressing System Limitations
What to consider in an iRODS deployment
iRODS will run on a laptop or a rack of servers
What does iRODS actually do?
Core Competencies
Data Virtualization
Combine various distributed storage technologies into a Unified Namespace
iRODS provides a logical view into the complex physical representation of your data, distributed geographically, and at scale.

Data Discovery
Attach metadata to any first class entity within the iRODS Zone
iRODS provides automated and user-provided metadata which makes your data and infrastructure more discoverable, operational and valuable.
Metadata Everywhere
Workflow Automation
Integrated policy engine which is triggered by any operation within the framework
The iRODS rule engine provides the ability to capture real world policy as computer actionable rules which may allow, deny, or add context to operations within the system.
Dynamic Policy Enforcement
The iRODS rule may:
Dynamic Policy Enforcement
A single API call expands to many plugin operations all of which may invoke policy enforcement
Plugin Interfaces:
Secure Collaboration
iRODS allows for collaboration across administrative boundaries after deployment
iRODS provides the ability to federate namespaces across organizations without pre-coordinated funding or effort.
iRODS Service Interface
Federation - Shared Data and Services
Institutional repositories
As data matures and reaches a broader community, data management policy must also evolve to meet these additional requirements.
