This is an overall approach of designing the Pre Processor, leave Processor, Trust Processor and Eligibility Processor
for Contract Administration. The processors have been coded into 3 layers – Business Logic, View and Transfer
Object. Business Logic – The primary and sole responsibility of this tier is to handle and execute business processing of
entities. This layer consists of controllers which encapsulate the business logic and creates or consumes Business
domain objects (Models) which encapsulates the business data and the methods which operates on data. This tier makes
calls to the DAO’s and MethodInterface (which executes the rules based on the rule sequences in the database). The
controllers have no state within them, all the data is contained in the Transfer Objects.

internal systems like Oracle GL, AP and PO.
System was so powerfully designed that all the messages were sent to particular queues and topic where they were
published to the concerned channels and triggers the Java processes. Peoplesoft SQR and AppEngine programs for
Payroll, benefits, 401 k calculations were used to generate the xml messages to trigger the WLI applications for further
processing.
Responsibilities:
