5.1 OPENING VIGNETTE: INFORMATION information in order to discover hidden truths within the data. Data portals have emerged as the SHARING A PRINCIPAL COMPONENT next generation in Web-enabled data warehouses. One of the most significant data portals has OF THE NATIONAL STRATEGY FOR been developed in direct response to the terrorist attacks on the United States on September HOMELAND SECURITyl 11,2001.

The National Strategy for Homeland Security of the United States includes a National Vision for the sharing of information related to the detection of terrorist activities. It states,

We will build a national environment that enables the sharing of essential homeland security information. We must build a system of systems that can provide the right information to the right people at all times. Informationwill be shared "horizontally" across each level of government and "vertically" among federal, state and local governments, private industry and citizens. With the proper use of people, processes, and technology, homeland security officials throughout the United States can have complete and common awareness of threats and vulnerabilities as well as knowledge of the personnel and resources available to address these threats. Officials will receive the information they need so they can anticipate threats and respond rapidly and effectively.

The goal of the project is to create a workable model for integrating knowledge that resides across many disparate data sources, while ensuring that privacy and civil liberties are adequately safeguarded. The five major initiatives that are identified within the strategy include:

1. To integrate information sharing across the federal government

2. To extend the integration of information sharing across state and local governments, private industry, and citizens

3. To adopt common metadata standards of electronic information relevant to homeland security

4. To improve public safety communication

5. To ensure reliable public health information.

CHAPTER 5 DATA WAREHOUSING, ACQUISITION, MINING, BUSINESS ANALYLTICS AND VISUALIZATION

These goals can only be accomplished if there is a means to facilitate the sharing of information among numerous agencies that currently maintain independent data silos.

Border security alone engages eleven agencies. For the entire data warehouse project, approximately 80 percent of the architecture will be in place in 18 months, while the complete implementation will phase in over three to five years. Ultimately the data warehouse will lead to increased security for the United States. It will be a model for how all countries can interact to protect their borders and ensure the safety of their citizenry. This ambitious project is not without challenges. For example, data will need to be mined from immigration records, treasury records (dealing with the exchange of large su.ms of money), and FBI (criminal) records. The data exist in different formats and data types; a major effort is underway to establish a means to link and search through these data to identify potential threats and crimes .
