Integration Between Blackboard Learn™, Release 9.1, Vista 8, Others and PeopleSoft - with a Catch

Integration Between “Things”™ - with a Catch
Chris GreenoughNorthern Arizona University
Chris.Greenough@nau.edu@GreenO

Background
Initially PeopleSoft extracts were IMS Enterprise 1.01 Vista 3 was IMS Enterprise 1.1
Needs in our SIS did not match the needs in our LMS
More need around campus for enrollment data
Constant development since 2008

What’s wrong with direct Integration
Data in your SIS is not Life in your LMS
Incompletes
Guests Lecturers
Cross Listed Classes (What a mess)
Name Changes
Anything else you can think of!

Basic Overview
Export
Logic
Import

Technical Details
Originally written in Java ported to Python
“Event”/Snapshot based
LMS Enterprise 1.1 Based
Oracle Backend
Multiple Destinations

Inbound Sources

Business Logic
IMS Enterprise Based Objects
Business Logic
Update Local Database
Apply “Override” Information
IMS Enterprise Based Objects

Outbound Sources

IMS Objects
Objects
Group
Relationship
Properties
Membership
Member
Bulk load
Methods to get override values(default) and underlying values

DB Schema
LMS_GROUP_INFO
LMS_MEMBER_INFO
LMS_ENROLLMENT_INFO
LMS_DESTINATION_INFO
LMS_OVERRIDE_INFO
TABLE_NAME
TABLE_ID
FIELD
VALUE

Web Service Integration
Vista
Multipart IMS XML Web Upload to SIAPI
BBLearn9.1
WS-Security SOAP requests to API
Using Internally Developed BbPy Web Service Bindings

Conclusion
There is a need to control every field of data from the SIS to the LMS
Distil all sources to common data sources, IMS Enterprise Spec
Separate inbound and outbound data
Hopefully LIS will help the connections
Allows for future expansion
