pattern is composed of several atomic patterns, where they directly govern the following
canonicalizations:
•
Canonical Expression
: This indicates expressing contracts' capabilities (opera-
tion) in a consistent and comprehendible way, improving discoverability, and con-
sequently, reusability.
•
Canonical Protocol
: This means reducing the number of communication proto-
cols to the optimal level. It is essential to maintain composability.
•
Canonical Schema
: This denotes establishing canonical data models, and redu-
cing transformations and as a result, improving performance and the overall re-
usability.
According to the AIA methodology, the adapter framework is usually realized by BPEL.
This advice has very strong historical reasons because the very first version of BPEL had
dozens of different connectors presented as partner links to DB, Files, FTP, MQ, and so on
(see the following screenshot). Adapters are arguably the strongest part of Oracle BPEL.
The framework is extremely extensive and provides the possibility to link to third-party
adapters.
Oracle Application Adapters have also been one of the strongest selling points for BPEL.
With these types of adapters, we can natively communicate with OEBS PL/SQL concur-
rent APIs, shadow tables, and custom interfaces:
