Oracle Service Bus is a configuration-based, policy-driven enterprise service bus.
#Credit card validator java registration#
Oracle Service Bus provides the following composite registration and security benefits:Ī business service registers the composite URI of the SOA composite application.Ī pipeline validates the SOA composite application before invocation.Ī proxy enables customers to invoke the composite through a proxy instead of connecting directly to the composite. The composite sensor tracks credit card payment status.Ĭomposite sensors provide a method for implementing trackable fields on messages. These include Oracle database servers and any relational databases that follow the ANSI SQL standard and provide JDBC drivers.Ī BPEL scope activity template is imported that includes a transformation activity that determines the payment status (authorized or denied) based on the daily limit and total order amount.Ī SOA template is a reusable part of an Oracle SOA Suite project that you use to create new projects. The database adapter enables Oracle SOA Suite and Oracle Fusion Middleware to communicate with database endpoints.
If the credit card number is not available in the database, payment is denied. The database adapter stores and retrieves credit card payment information from the database, including payment type, card number, expiration date, card name, and daily limit. BPEL processes orchestrate and build process automation. BPEL is the standard for assembling discrete services into an end-to-end process flow. The BPEL process (and its activities) orchestrates the validation of credit card payments and returns a payment status (invokes a database adapter).īPEL processes provide a comprehensive and easy-to-use infrastructure for creating, deploying, and managing business processes. Implement the business logic or processing rules of the application.Įnable messages to be sent from the SOA composite application to external services in the outside world. Provide the outside world with an entry point to the SOA composite application. SOA composite applications consist of the following: The composite consists of the following components, each of which is briefly described below:
If payment is denied, an order is not processed. How This Component Addresses The Business ChallengeĪ SOA composite application is designed to validate payments and return status. Table 3-1 Components That Provide the Business Solution Component In the future, when Company X decides to outsource credit validation to an external provider, this can be accomplished without impacting existing applications. However, once the interface is stabilized, this service is to be outsourced to a third party provider. The consolidated credit validation service is to be initially hosted in-house to control quality. The first step is to provide a consistent interface for all order entry applications for credit validation. A consistent fraud mechanism requires the credit validation process to be consolidated across all order entry systems. Orders become lost and delayed in the system, causing customer dissatisfaction.Ĭompany X has determined that a new credit card fraud detection system must also be in place at year's end to eliminate credit card abuses. Since the process to correct these issues varies across Company X's order entry systems, there is no consistent follow-up and resolution to customers.
A key area for improvement is the need to streamline the ordering process to provide better order tracking visibility through the following parts of the ordering life cycle:Ī key issue in their current system is that credit card payments are often denied for minor reasons. Company X has embarked upon a project to improve customer satisfaction.
