Role: Senior Java Developer.
PROJECT: EDI
Team Size: 10
Description: For the health care industry to achieve the potential
administrative cost savings with Electronic Data Interchange (EDI),
standards have been developed and need to be implemented consistently by
all organizations. To facilitate a smooth transition into the EDI
environment, uniform implementation is critical.
There are multiple methods available for sending and receiving business
transactions electronically. Two common modes for EDI transactions are
batch and real-time.Batch - In a batch mode the sender does not remain
connected while the receiver
processes the transactions. Processing is usually completed according to a
set schedule.If there is an associated business response transaction (such
as a 271 Response to a 270 Request for Eligibility), the receiver creates
the response transaction and stores it for future delivery. The sender of
the original transmission reconnects at a later time and picks up the
response transaction. This implementation guide does not set specific
response time parameters for these activities.
