The GIF is an Architecture Blueprint
 It addresses all Information Systems needs and requirements
 It encompasses:



web access
manipulation of data
interagency access of data
intra-agency access of data
network messaging
granularity of data
multidimensional processing of data
metadata
security

Motivation for an Architecture
Governments are non profit organisations
The following issues influence the recognition and need
to implement an Information Systems Architecture:
 driving down the cost of processing reducing budgetary expense
 improve level of service
 enhance overall control
 speed of access of data
 accuracy of data once data is found
 integrity of data

The Government Information Factory
Components
 Operational Environment – the transaction oriented environment
where detailed data is captured as a by product of conducting
day to day business
 Informational Environment – an environment separate and apart
from operational. In the informational environment decisions are
made which are strategic and long term, looking over a large
vista of data.
 Analytical Environment – an environment used to produce
analysis for management decisions, usually involving trend
analysis, drill down analysis, demographic analysis, profiling etc.

Operational Components
 Online Transaction Processing (OLTP) Systems
 Staging Area
Extract Transform & Load (ETL) Environment
Communication Mechanism

The Government Information Factory
Informational Environment Components
 Data Warehouse – where integrated atomic & historical data resides
 Data Mart – different departments have their own data mart shaped to
meet their information needs. Multi dimensional technology is used here
 Adaptive Data Mart – specific to a business person for non-technical analysis
 Data Mining/Data Exploration mart – where deep statistical analysis is done
looking for specific patterns previously undetected
 DSS applications – where informational functions are executed
 Operational Data Store – a hybrid processing place where “real time”
data warehouse processing is done

GIF and the Web
 The Web doesn’t populate the DW directly
 The WEB is an OLTP system
 The interaction is between the Web and the ODS and the ODS
to the Data Warehouse
 The GIF supports large volumes of data
 The GIF provides consistent and good response times
 The GIF allows web data to be integrated with corporate data
 The GIF allows trends for business to be identified

Archival Storage

The Government Information Factory
Archival Storage Components
 Archival storage is used to remove dormant or old data from the DW
 It uses:
 high performance disk storage – can be accessed online
 Near line storage – can be accessed in near online time
 Archival storage – cannot be accessed online
 Archival storage is managed by CMSM software needed to control
the movement of data to and from archival storage. e.g. Princeton software

Using The Blueprint
 The Government Information Processing is complex and substantial in scale
 The systems entail many different kinds of technology
 The requirements are ever changing
 Users keep changing their minds
 A means of dealing with this chaos is an Architectural Blueprint

Using The Blueprint Continued
The Blueprint needs to consider the following:
 Today’s reality and tomorrow’s requirements
 The intersection and interfacing of many different technologies
 The merger of different political interests
 Long-term trends as well as today’s needs, and so forth.

Coordinating Development Efforts over time
The primary use of the architecture is to enable different development
efforts in progress over time

Prioritisation
 The blueprint shows all the work that needs to be done
 It shows a general flow of data and activities

Design Comparisons
The blueprint provides a guideline as to the best way to structure a system:
 In a manner that satisfies the requirements specified by the blueprint
 In a manner that is best patterned by the form suggested by the blueprint
 It allows the comparison of many designs to the target design

Comparing today’s environment to tomorrow’s environment
 Most government agencies operate a “stovepipe” environment
 Data is not integrated
 Technology is outdated
 New systems only contribute to the conditions of the stovepipe getting worse
 Maintenance is difficult

A basis for people working together
 A center point of people working together
 Analysts and users meet
 Technicians and end users meet
 Different departments meet
 Other agencies meet
 The systems environment is the crossroads of many different organisations
that use and partake in the organisation’s charter

Using The Blueprint Continued
The opportunity to bring together many different considerations
 Performance. Will transactions run in a timely manner?
 Availability. Will the system be up and running when needed?
 Accuracy. Are the numbers produced by the system credible?
 Cost. Will the cost of the environment be exorbitant?
 Scalability. Will I be stuck at one volume of data and transactions with
no growth path?
 Responsiveness. How quickly can I change in accordance with new
requirements?
 Reconcilability. If two organisations produce similar but conflicting
results, how can I resolve it?

How other people addressed the problems I face today
The blueprint is based on best practices and experiences

A long term Vision
The Blueprint is a “blue sky” vision that may never be achieved,
but if we don’t have a goal then “any road will do”.
We wouldn’t build a house without a blueprint, then why do we do it
with complex IT systems?

Estimation
Often we are asked questions such as:
 How many users will there be?
 How many processors will we need?
 How long will development take?
 What will be the rate and frequency of data transfer?

Focus
 With a blueprint it is possible to see
the world at different levels, that in
turn enables us to focus as the levels
change.

Summary
 The GIF is an Architectural Blueprint for Federal, State and
Local agencies, and addresses the need for:
Operational processing
Informational Processing
Analytical Processing
Managing very large amounts of data
Being responsive to changing and unknown conditions
High availability
Good response time for transactions
Data Mining and exploration
 The GIF also takes into account:
Interagency passage of data
Integrated electronic security
Predictive security (ability to use data to predict threats
before dissasters occur)
Reconciliation of data
Addressing the challenges of stovepipe systems

Summary Continued
 The GIF is built incrementally as business needs dictate
 The entire blueprint may only be required for very large organisations
 When it comes to systems modernisation The GIF is the premier
blueprint for government agencies

drive down the cost of processing reducing budgetary expense
to raise the level of service
enhance overall control
 speed of access of data
 improve accuracy of data once data is found
 integrate data
