Differences between adapters
This topic describes the differences between the previous version
of the WebSphere® Business
Integration Adapter for JText and the new WebSphere Adapter for Flat Files.
There are two main differences between the previous version of the WebSphere
Business Integration Adapter for JText and the new WebSphere Business Integration
Adapter for Flat Files. The architectural and functional differences are listed
below.
- Architectural differences
- Protocol split - With the WebSphere Business Integration Adapter
for JText, the adapter combined the functionalities of both the local file
operations and FTP file operations. With the WebSphere Adapter for Flat Files,
the adapter only deals with local file operations. This functional segregation
makes the adapter more maintainable and more specialized for protocol-specific
operations.
- Perception of an inbound event - With the WebSphere Business Integration
Adapter for JText, individual data records in the event file were considered
to be events and the adapter parsed the event files to extract the record
content. With the WebSphere Adapter for Flat Files, the entire file is considered
an event and the adapter does not parse the event file. This architecture
was chosen in order to separate the different tasks involved with both file
handling and data transformation. File handling deals with the entire file,
which involves detecting the arrival of event files for inbound processing,
reading the entire content of the file, and writing the file content for outbound
processing. While data transformation involves file parsing and extracting
data records out of the file. This split between protocol handling and data
transformation makes the individual components more reusable and maintainable.
- Functional differences
- More outbound processing functionalities - The WebSphere Adapter
for Flat Files supports more operations for outbound processing compared to
the WebSphere Business Integration Adapter for JText. The WebSphere Business
Integration Adapter for JText request operations supported only create, append,
and overwrite through the appropriate meta-object configuration. While the
WebSphere Adapter for Flat Files supports create, append, overwrite, retrieve,
delete, exists, and list operations.
- File splitting feature available for inbound processing - With
the WebSphere Adapter for Flat Files, an event file can be delivered to an
endpoint in specified chunk sizes.
