Proof of Concept Project Undertaken
ADAM Proposal Submitted and Approval Granted
ADAM System Pilot Releases (May 13 & June
17, 2005)
The ADAM Solution
• A standard programming methodology for
cross-state access to ALMIS data over the
Internet
• A means to query and compare data across
multiple states simultaneously – local state
data, remote state data, local/remote state
data, remote/remote state data
• Participating States control who and how
user access their ALMIS data
• A flexible system, with customizable
interfaces, queries and data access security
options
Major Goals of the ADAM System

Focusing on the ALMIS Core tables for the Pilot Project
Demonstrating Access Security Methodologies
Control of query execution and data access
Distributed Computing – No Single Point of Failure
Robust Extensibility

Non-ALMIS Tables
Major Goals of the ADAM
System con’t

Flexible Web Functionality – Offering States three
options for accessing the system:

Utilization of the ADAM Display Tool provided

Adaptation of existing state-specific web applications

Creation of new state-specific web applications
Pilot States

ADAM – Technical Details –
Technologies Used





XML – ADAM Queries are written in ANSI SQL and translated into
XML documents
SOAP – SOAP is the messaging protocol used to transport the XML
documents securely between the ADAM Server and the ADAM
Webtool
Database Options 
MS SQL – 1 of 2 types of ALMIS Databases supported by the ADAM
System

ORACLE – 1 of 2 types of ALMIS Databases supported by the ADAM
System
C# - Programming language in which the ADAM System was
developed
RSA/DES – ALL communication between the User, the ADAM
System, and the ALMIS Database is encrypted using RSA and DES
ADAM – Technical Details – Two State

It Contains:
• State’s ADAM Directory Address
• XML Queries
• Query Execution Function
• ADAM Administrator Application

User Accesses the ADAM Webtool
Through the Webtool, user in State A. Accesses the ADAM Server in State
A
State A Recognizes that user is requesting data from State B and transmits
to the Webtool the Address for State B
Webtool Accesses State B
User Selects Query to run
Based on the query selected, ADAM Server dynamically provides
parameter options for the user to select from
User selects from parameter values to filter query results and submits query
ADAM Server uses database profile information in the repository, user
provided parameter information to create dynamic SQL statement to run
against the database
Database returns results to the ADAM Server
The ADAM Server performs data suppression based on user id and role,
converts results into XML and moves it to the calling application to present
to user
