From a service-oriented logical architecture
perspective, however, an ESB is an abstraction that depicts integration functionality and
enables transmission of messages across heterogeneous technological environments.3 Consider
the following major ESB contributions to organizational interoperability challenges:
??? Enables protocol conversion
??? Offers data transformation
??? Provides application adapters for schema translation
??? Dispatches messages by employing routing and workload mechanisms
??? Manages business processes by utilizing orchestration features
??? Supports synchronous and asynchronous communication protocols
USING ADAPTER TECHNOLOGY. Interoperability hurdles can also be mitigated by employing
widely available adapter technology. Adapters are software connectors that facilitate seamless
communication and data exchange between consumers and services. They are often called connectors
because they are ???pluggable??? assets that can be easily installed and configured and they
also enable protocol or data translation between the message exchange parties.4 Adapters are
typically installed on legacy application premises to enable their compatibility with their corresponding
consumers. A logical architecture should employ this concept to universalize the
various data formats and protocols used by a technological environment. This holistic view of
overall communication needs can bridge the various nonconforming technology standards in an
enterprise.
