The pattern language presented in the book consists of 65 patterns structured into 9 categories, which largely follow the flow of a message from one system to the next through channels, routing, and transformations. The pattern language continues to be relevant as of today, for instance in cloud application development and integration, and in the internet of things.

This article has multiple issues. The desire for consistent message payload results in the construction of an enterprise or business domain canonical model common view within a given context. Often the term canonical model is used interchangeably with integration strategy and often entails a move to a message-based integration methodology. A typical migration from point-to-point canonical data model, an enterprise design pattern which provides common data naming, definition and values within a generalized data framework. Advantages of using a canonical data model are reducing the amount of data translations and reducing maintenance effort. This page was last edited on 11 January 2018, at 15:15. TIBCO BW provides options of utilizing code written in java to develop integration solutions by making use of Java Palette activities.
Java Palette activities should be used on top of the standard Palette activities provided by TIBCO BW? When Java Palette activities to be used? I am going to talk about some generic situations where you may need to opt for utilizing Java Palette activities while working on your TIBCO BW Projects. TIBCO BW is quite rich in providing a large number of activities and resources grouped in different palettes which are used to design and develop processes for fulfilling different business needs. However, there can be the cases where the available palette activities are not sufficient enough to get certain problem solved.
That’s one situation where you look into the possibility of coding your desired methods in java and then incorporate the java code in your TIBCO BW project. Java Code where you can utilize the libraries for photo editing and then incorporate those classes in your project. Another example scenario is dealing with PDF documents. Java classes for PDF creation and then make use of those in TIBCO BW projects. The above two are just example scenarios and there can be dozens of other scenarios where you may feel it necessary to augment TIBCO BW functionalities with custom Java codes. TIBCO BW projects by using Java Palette. TIBCO BW provides different types of process starters to interface with a variety of external systems and applications for HTTP, JMS, RV, Timer, adapter etc.
It is important to keep in mind some of the key points while deciding to use external java code in TIBCO BW projects. Performance should always be considered first when importing external jars or when writing custom Java code for BW solutions. The functionalities provided in different standard palette activities of TIBCO are generally much efficient and robust. Java code only when no other option is available. TIBCO BW XML palette has Render and Parse XML activities which are quite efficient to handle large XML files. Writing custom Java Code for XML handling won’t make much sense here unless you have some solid reasons to do so.
