  1. Kuali Nervous System Aaron Godert, Cornell University Jonathan Keller, University of California, Davis

  2. Outline • What is the Kuali Nervous System? • Where did it come from? • What does it do? • And, what's Rice got to do with this?

  3. What is the KNS? • KNS = Kuali Nervous System • An application development framework that KFS and KRA are built on • Allows for pattern based integration with other middleware components • Focuses on providing a foundation for efficient development of business functionality • Helps to ensure consistent development practices

  4. KNS is a Rice Component • What is Kuali Rice? • Kuali: a humble kitchen wok; Malaysian origins • Rice: it is what it is • Sits on the bottom of a dish • Not a very tasty meal by itself • Better with some substance on top • KFS - Beef • KRA - Chicken • KS - Seafood • Rice is the foundation to a hearty software product

  5. The Goals of Rice • The board vision for Kuali is a plug and play module by module approach to software • Kuali started as financials, but has evolved into a suite of administrative software (KFS, KRA, KS) • A lot of functionality in Kuali systems • Keeping the Kuali code base as small as possible without impacting quality is key • Highly productive development environment • For Kuali projects • For non-Kuali projects

  6. Rice Goals Cont. • A common and consistent architecture • Allow developers to understand other rice enabled projects • Infrastructure would not need to be reinvented on each project - focus on functionality! • Rice team can focus on IT standards, like SOA, that will benefit the entire Kuali software suite • Adoption of other Kuali modules feasible • Generic enough for non-Kuali applications • KNS plays a major part in this!

  7. How We Got Here • Kuali Enterprise Workflow (KEW) existed in production at Indiana University • Kuali Finanical System (KFS) started development and had an architecture team • Morphed into the Kuali Nervous System (KNS) team • Achieve technical consistency across all aspects of KFS • KFS --> KNS --> KEW

  8. Along Came KRA • Kuali Research Administration (KRA) wanted to reuse the core features • KRA needed to integrate with KFS • Align our core to support sharing services across Kuali apps in a loosely coupled fashion • All Kuali products should be technically consistent under the hood • For end user functionality • For different development methodologies

  9. Rice Was Born! • KEW Kuali Enterprise Workflow • KNS Kuali Nervous System • KSB Kuali Service Bus • KEN Kuali Enterprise Notification • KIM Kuali Identity Management

  10. History of the KNS • KFS spent a large amount of development time up front, using the best talent from each of the partner institutions • Came up with a foundation on which to build KFS - the Kuali Nervous System • It focused on a unified approach to development of functionality • A standard way to use workflow, perform CRUD operations, handle business transactions • KNS extracted from KFS and put into Rice as a module

  11. KNS Overview • Provides reusable code, shared services, integration layer, and a development strategy • Provides a common look and feel through screen drawing framework • A document (business process) centric model with workflow as a core concept

  12. Understanding the KNS Paradigm ENTITY_T Entity(POJO) Data Dictionary ORMMapping Lookups and Inquiries MaintenanceDocuments TransactionalDocuments Workflow(KEW)

  13. Transactional Documents • These are data-entry centric documents or “transactions” that model the business processes • Examples include: Proposal Development, Journal Entry, Payment Reimbursement • Built on a case by case basis using the Kuali Rice tag libraries (encompass snippets of UI behavior): • Notes and attachments • Workflow route log (audit log) • Integrated with workflow

  14. Maintenance Documents • They do not need to be built case by case - just one JSP that draws them all • These are the CRUD documents - an easy way to maintain support tables in a Kuali database • C: Create new table records • R: Read or query table records • U: Update existing table records • D: Delete existing table records • Examples include: • Budget rates • Project codes

  15. Inquiries • A way to drill down and get more read-only information about a table record

  17. Inquiry Example Configuration <inquiry> <title>Travel Account Inquiry</title> <inquirySections> <inquirySection title="Travel Account"> <inquiryFields> <field attributeName="number" forceInquiry="true" /> <field attributeName="name" /> <field attributeName="accountType" /> <field attributeName="foId" forceInquiry="true" /> </inquiryFields> </inquirySection> </inquirySections> </inquiry>

  18. Lookups • A way to search for data by a set of criteria • Results of lookups can be returned to other lookups or documents

  20. Lookup Example <lookup> <title>Travel Account Lookup</title> <instructions>Look up Inst.</instructions> <defaultSort sortAscending="true"> <sortAttributes> <sortAttribute attributeName="number" /> </sortAttributes> </defaultSort>

  21. Lookup Example Cont. <lookupFields> <lookupField attributeName="number" required="false" /> <lookupField attributeName="name" required="false" /> <lookupField attributeName="accountType" required="false" /> <lookupField attributeName="foId" required="false" forceLookup="true" /> </lookupFields> <resultFields> <field attributeName="number" forceInquiry="true" /> <field attributeName="name" forceInquiry="true" /> <field attributeName="accountType" forceInquiry="true" /> <field attributeName="foId" forceInquiry="true" /> </resultFields> </lookup>

  22. Other KNS Features • Data Dictionary • Question component • Notes and attachments • Pluggable business rules • Pluggable authorizations • System parameters • Extended/custom attributes

  23. What Does the KNS Do? • Reusable Modules • Data Persistence • Document Framework • Business Rules / Validation • Lookups • UI Components • Maintain Consistency • Set of Services

  24. Data Dictionary • Business Objects • Attributes • Lookups • Inquiry Page • Relationships • Document Definitions • Sections • Fields • Collections

  25. Persistence Framework • Business Objects • Collections • Security • Field Encryption • Masking • Extendable

  26. Business Objects • Attributes • Labels • UI Widgets • Validation • Attribute References • Lookups • Inquiries

  27. Documents • Maintenance Documents • Edit Business Objects • Rigid Layout • Transactional Documents • e.g., Financial Documents • Free-form document layout

  28. Maintenance Documents • Created without code • XML File Definition • Fields on Document • Sections • Locking • Business Rule Linking • Collections

  29. Business Rules • Rules • onSave • onRoute • onApprove • onAddLine • Pre-Rules • Can ask questions

  30. Authorization/Security • Module Level • Document Level • Field Level • Read Only Fields • Hidden Fields • Masked Fields
