DARS on the Web
Audits & Exceptions delivered by our Homegrown Systems
Project Goals
• Create an on-line degree outline accessible to
students and advisors
-- Objectives
1. Provide better advising for students
2. Check prerequisites to stop students from enrolling in courses
for which they are not prepared
3. Allow students to plan their academic career with certainty
4. Allow students to do “What if” audits by evaluating their course
work against a particular degree

Project Goals
• Enable our advisors to provide student exceptions and
degree audits processing
-- Objectives
1. Better placement of transferred courses on degree audits,
ELNA (elective non-advanced) and ELADV (elective advanced)
2. A mechanism for tracking substitutions that have been
approved by the college deans in a degree program
3. A mechanism for confirming that a student has completed all
requirements for a degree and is eligible to graduate

Approach
• Programming tasks:
1. Development of SWT Degree Programs for all Colleges (Started with
the undergraduate degrees)
2. Installation of DARwin Client/Server on a PC Windows environment
(Used for development & testing of degree programs)
3. Data Access between DARS tables and Mainframe datasets (Upload
& download modules)
4. Conversion of DARwin Daemon for the Mainframe environment

DARS Degree Programs index web pages (Batch module, used by the
Degree Audit Reports module)

5.
Get the job done with limited staff resources
Fit into our current Student & Administrative Services
Security well established for sign in/out
Wide client, database and browser compatibility
Ability to turn audits on/off
-- Cons
1. The DARwin new releases are “more difficult” to implement
2. Longer development time than other solutions

DARS Driver
• Conversion process:
-- Phase I – DARS CICS version with VSAM structure
1. Major unresolved data structure differences
2. Three months of development lost – Didn’t work for us!!!
-- Phase II – DARwin Client/Server with ODBC SQL structure
1. Adaptation of Micro-Focus Cobol code to mainframe environment
2. Replacement of SQL statements with S1032 commands
3. Data manipulation in the DARS driver to improve layout
readability & performance
4. Manipulation of the DARS driver modules, libraries and objects
by using the mainframe management tools
5. Execution of the DARS driver as a callable shareable image to
save memory

To-Do List
• Unfinished business:
1. Modify the Mainframe DARS Exception module to support the
schedule modification exceptions (Needed by the Graduate College)
2. Add to the Mainframe DARS Exception module our own SWT
exceptions (Needed by the Graduate College)
3. Modify the DARS Degree Program indexes module (Split degree
programs between Undergraduate & Graduate Colleges)
4. SWT Course Inventory report (Batch module, used to check data
integrity)
5. Graduation certification using DARS (Certify SWT students have
completed all of the qualifications for graduation)
• Upgrades:
1. Upgrade DARwin Client/Server to the latest version
2. Conversion of DARwin Daemon to the latest version
