Business Process Execution Language

Business Process Execution Language, or as it is better known “BPEL” can greatly reduce an organizations maintenance costs and improve organizational flexibility, especially when combined with a Services-Oriented Approach.  Oracle’s BPEL Process Manager and Designer allows organizations to move from an object oriented way of managing business processes to a service oriented approach and services are becoming fundamental elements of application development.

Consider your business’ decision points and I’m sure there are multiple ones. At these decision points, certain data is evaluated. Based on this data or business rules, processes change their behavior. In other words, business rules steer the business process. Changing these rules is a complicated task, beyond the abilities of most business analysts. Since these rules cannot also be reused, IT personnel end up creating new rules for every new process.


The best way to avoid this scenario is to use the tools BPEL offers to organizations. Here at eAlliance our consultants are well versed in BPEL and the many benefits it offers to your IT structure. Oracle’s BPEL Process Manager provides high-level tools to visualize, design, and manage BPEL process flows. Contrary to popular belief, BPEL is a standardized, easy to learn, and highly expressive language for specifying how Web services can be sequenced into productive transactional process flows. Vendors are moving quickly to provide BPEL or BPEL compliant products to their customers.


Oracle offers a particularly comprehensive and integrated suite of tools. The benefits realized from using these tools range from greatest ease of use and advanced scalability to being hot-pluggable with software from vendors such as IBM, BEA and Jboss. Those benefits are enhanced by the fact that BPEL is truly portable across platforms.


The scope included in the use of BPEL to model the behavior of both executable and abstract processes is:
• Sequencing of process activities, especially Web Service interactions.
• Correlation of messages and process instances
• Recovery behavior in case of failures and exceptional conditions
• Bilateral Web Service based on relationships between process roles.
