The Dream of a Common Language:Extending the Role of the Logical Data Model
DAMA-NCR MeetingJanuary 10, 2006Deborah L. Brooks

Agenda
• The Beginning
• The Journey
• The Dream
3
Background
Automated Commercial Environment (ACE) Program
• First focus of the Customs & Border Protection (CBP) Modernization Initiative
• Supports CBP’s priority mission by:– Assisting in targeting high-risk cargo– Improving previous measures against the threat of terrorists and terrorist
weapons– Expediting legitimate trade
4
The Beginning
The ACE Logical Data Model (LDM)
• Representation of the information needs for cargo-related business operations
• Foundation for physical database design for ACE releases
• Contains:– 50 Subject Areas– 925 Entities– 10084 Attributes
5
Impressive, but is it right?
Desired LDM characteristics:
• Complete• Correct• Consistent• Integrity• Aligned• Integrated
6
The Journey
ACE LDM Validation Goals
• Confirmation of existing entities, attributes and relationships
• Identification of:– Missing entities, attributes and relationships– Incorrect relationships– Redundant entities, attributes and relationships– Unused / irrelevant entities and attributes
7
Horizontal Integration
Notes: • ACE Concept of Operations (ConOps) contains high-level business process flows.• ACE Business Process Architecture (BPA) is currently under development. The CBP Enterprise Business Process Architecture (EBPA) and ACE Release Business Processes (BPs) were used as a proxy for ACE BPA.

10
Benefits
• Cross-validation of other architecture artifacts (ECDM, BPA)
• (Identification of process overlaps across ACE releases)
• Easy identification of implementation timeframe through color-coding of ACE LDM entities by ACE Release
• Positioned to support federal information-sharing initiatives such as the Federal Enterprise Architecture (FEA) Data Reference Model (DRM) at either a logical or physical level
11
Information Sharing
Extended the links to the ACE LDM for:
• Information Sharing Stakeholders– Mapped ACE LDM to external organizations – Indicated if organization is a Consumer of data from ACE or Provider of data
to ACE
• Standard Trade data interface
12
International Trade Data Set Standard Data Set
• Collection, use and dissemination of trade and transport data
• Supports the international trade process and U.S. border regulations and enforcement responsibilities
• Contains 1060 standardized data elements representing the harmonization of 8900 agency data elements from 21 Participating Government Agencies
13
International Trade Data Set Standard Data Set Links
• Participating Government Agency Data Elements
• World Customs Organization Trade Data Model– Parallel data harmonization effort– Facilitates the exchange of information between government agencies that
regulate international trade
• National Information Exchange Model (NIEM)– NIEM 0.2 Pilot– New International Trade domain

New Acronyms:• Information Sharing Stakeholders (ISSs)• International Trade Data Set (ITDS) Standard Data Set (SDS)• Participating Government Agency (PGA) Data Elements (DEs)• World Customs Organization (WCO)• National Information Exchange Model (NIEM)
15
Benefits
• Traceability of WCO and PGA synonyms to ACE LDM attributes to ACE Release PDM attributes
• Identification of all ACE information-sharing stakeholders, including those PGAs participating in ITDS, and the definition of Communities of Interest (COIs)

17
Benefits
• Traceability of requirements to ACE releases
• Confirm scope of release implementation for data (and process)
18
Data Transition
• Associate source system data structure to target ACE Release data structure
• Use ACE LDM as common denominator

20
Benefits
• Ensure transition of data to same logical concept
• Reduced complexity of mapping effort; map each source system data structure once to ACE LDM regardless of how many ACE releases are involved
• Same principle applies for one-way data conversion or ongoing data exchange. Target data structure can be a PDM, LDM, COTS, Interface parameter, etc.

LDM Role Extension
• Uses the ACE LDM a a fulcrum to to support– Information sharing– Data Transition– Requirements Traceability
in addition to more traditional role of depicting business data requirements and driving physical database design
• ACE LDM moves from an architecture artifact to an active, integral role in the management of information in the CBP enterprise
24
Technical Implementation
• Most links are documented in Telelogic’s System Architect (SA); Business Rules, Quality Objectives and Assessments are in MS Access
• Added new SA Definition Types:– Business Organization– Validation Reference
– ConOps Scenario Step– Business Process Definition– Use Case– EBPA Process– ECDM Conceptual Entity
– PGA Alias– …
25
What’s Next
TBD, but could include:
• NIEM Mapping for full ACE LDM content
• Additional taxonomies to support information sharing at a federal level
• Leverage ACE LDM for Data Governance activities such as definition of data stewards and owners, data security and privacy requirements, data retention requirements, etc.
• Limited only by our imagination….
