Major Focus of the Presentation
The primary focus will be on the interoperability of the portal with your backend systems
There are many pieces to this puzzle. The most critical of these will be covered. Some of these issues have been discussed before in the other presentations. Those addressed here will all come together to make your portal a very nice tool for your users or just another application for which they will need to remember a userid and password.
The Pieces…
Establishing both, short term and long term target users
Determine authentication mechanism Using centralized roles/rules to access
data in disparate places
The Pieces…
Establishing trusted, secure connections to external processes and data
Enabling access to external applicationsResources for the actual
implementation of the portalOther issues relating to presenting
these data on a portal
Target Users for the Portal
Who do you need use a portal? This is for others to discuss but it is
important to know because it will/should influence the infrastructure needs
Students/patients Hard to limit browser type Somewhat limited application set
Staff/care providers Not quite as hard to limit browser type Very diverse application set
Target Users for the Portal
Other issues as well Scalability needs Password Management
Change frequently or change infrequentlyAbility to change passwordAbility to restore passwordCreate new userids
Multiple authentication mechanisms Multiple authorization mechanisms
Establishing Trusted and Secure Authentication
Methodologies
How do you know who the user is?Single signon - crosswalk database
Lots of variability on this issue
Establishing Trusted and Secure Authentication
Methodologies
Preferably the portal will work with already established authentication methodologies Authenticating the user using RACF Authenticating the user to an externally supplied
application running in another CICS region Using NDS/Active Directory authentication Using LDAP and Kerberos Using user an externally supplied application like a
PIN routine Authenticating the user at their home institution in
the state Florida - FACTS
Establishing Trusted and Secure Authentication
Methodologies
Very important to position yourself to be able to use the new technologies when they are matured and/or agreed upon
What Is the User Allowed to Do?
Combining roles into fewest possible number of databases
Trusted relationships for role passingRules that apply to information
retrievalCommon directory across the
enterprise
Using Centralized Roles to Access Data in Disparate
Places
Using data from disparate sources Mainframe
RDS report generation Proprietary CICS generated data
Network drives Java i.E..XAC Java dynamic PDF creation Report access
Using Centralized Roles to Access Data in Disparate
Places
External proprietary data bases Visual info imaging index queries Visual info images
Other sitesFACTS - retrieving real-time data from all
over the state of Florida
Enabling the Existence of “Portal Friendly” Applications
Participating in authenticationCross walk database to store multiple
userids• Proprietary • Kerberos• Browser cookies
Sharing state managementEnabling external state management
Coordinating logoffs
Enabling the Existence of “Portal Friendly” Applications
Sharing context (mainly for staff and care providers)Notification of when the student/patient
being viewed has changed
Resources Required to Produce and Retrieve
Needed Data
Current skill sets Of those who produce the data Of those who need the data
Current availability Of those who produce the data Of those who need the data
Resources Required to Produce and Retrieve
Needed Data
Current hardware capabilities Must allow for heavy peak loads Must allow for large number of users Reliable platform (always available) Of those who produce the data Of those who need the data
Current software capabilities Of those who produce the data Of those who need the data
Other Issues Relating to Presenting These Data
EDI systems vs. XML based communications Speed vs. standards based processing Development speed or delivery speed
Guidelines When Evaluating a Portal Infrastructure
What do you need on the portal? Need to decide on your business needs
Form vs. Function
Some infrastructure goals should be SPA - single point of access CARR - condensing authorization roles and
rules Simplified content management
