2 2 Topics Enterprise Data Architecture at the CIA Applicability across enterprises

3 Data Architecture Mission Statement Enable the mission by enhancing the value of data.

4 4 A Framework for Data Architecture make it easy to share within and outside the Agency centralized data repository enable more effective linguistic search and data manipulation reuse the data, so multiple entry of the same information is eliminated Some Business Drivers: Enterprise Data Model What things are important to us and how they are related Master Data Management Starting points and priorities Data Services Strategy Shielding applications from changes in data structure Repository Strategy Increasing data value by reducing data fragmentation Uniform Resource Identifier Telling different things apart Semantic Technology Strategy Knowing what we know and what it means

5 5 When We Started No enterprise data model to use for standardization Projects underway changing major data stores If we developed an EDM and then standardized, it would be too late to influence the major projects So we are aligning projects with the EDM as we build it We must address not just technical characteristics of data but also the data strategy for the enterprise. We are releasing a draft of our EDA every quarter in FY07, final EDA to be complete at end of FY07.

6 6 Subject Area Overview

7 7 Enterprise Data Strategy We are changing our data culture, from project- centric to enterprise-aware The scope of the change is huge--top management support is essential (and we have it) Enterprise Data Layer project provides public focus for our efforts to improve data value The business understands cleaning up data and putting it into the EDL Although data may not move to enter the EDL, nevertheless its a useful construct

8 8 Application View of the EDL Always available Subject to strong, consistent access control Discoverable Physically protected High data integrity Sharable Consistently represented

9 9 Enterprise Data Layer Defined The Enterprise Data Layer is a collection of data of interest to the enterprise, software used to access, manage and control it and hardware used to house and access it. The Enterprise Data Layer –is always available –makes all data discoverable –includes entity types, attributes and relationships in alignment with the Enterprise Data Model –has duplicate entity instances resolved and there is a unique enterprise identifier for each instance –is accessed through a set of enterprise access interfaces –has access to it controlled by enterprise access control –is physically secure

10 10 Middleware Data Mapping Enterprise Data Layer and Applications Enterprise Data Stores Enterprise Access Control Serv- ice Service Application

11 11 Enterprise Data Model The EDM is conceptual, shows only entity types and principal relationships Theres a lot that it doesnt show and doesnt control For master data entities, a logical data model will be developed that will show attributes and details of relationships Master data entities include the objects of interest to the community (Person, Organization, etc)

12 12 Use of Data Models in CIA Data Architecture Data models are not used to control storage structures Data model constraints apply to interfaces to the EDL, not to physical storage Data model constraints can be met logically through middleware or other multipurpose services, or at the storage level This flexibility is used to deal with legacy and with COTS

13 13 How Were Getting There We work with projects in development Every project is given an Enterprise Data Model Maturity Assessment Assessment can be from 1 (project-centric data management) to 5 (entirely enterprise-aware and compliant) Assessments are carried along with project status data Maturity level assessment provides a management tool to set goals and track progress

14 14 Next StepLegacy We are inventorying legacy data stores For each, we will develop an appropriate plan to bring each into the EDL Some will have storage structures changed, some will have storage structures emulated through middleware or other enterprise services

15 15 Duration of our Effort We can measure progress by EDAMM level and by amount of data in the EDL The effort wont be completed in a year; or five; or ten We will deliver mission benefit in the current FY and on a continuing basis This is like a quality effort; you dont stop

16 16 Whats Next We are constructing artifacts to make our EDAMM assessment as objective as possible –Features checklist –Mandatory content indicated on EDM –Logical data models for master entity types We are writing our EDA to describe the whole process –The document will be specific about EDAMM assessments –To be completed September 30, 2007; drafts quarterly –March 31 issue will be the first to include EDAMM

17 17 What About a Community? If youre talking about the whole federal government or the whole Intelligence Community, what should you do? We believe that it is not practical to force compliance with storage structures even within a single enterprise, much less across a federation of enterprises We are standardizing on interfaces, even within the enterprise In a community, why not standardize on information exchange and ignore how its stored?

18 18 The Conglomerate Model Enterprise Technical Architecture uses a concept called the conglomerate model Individual pieces are separate businesses Standardization is intended to allow interchange of information, not common infrastructure

19 19 Data Architecture for a Conglomerate Information exchange formats are required XML is the obvious choice for exchange But shared semantics for most important data is also needed, not conveyed by XML Agreement on conceptual data model for principal entities is needed
