To manage their valuable information, businesses often rely on a variety of standalone systems that may or may not be designed to exchange information with other systems, even within the same organisation. Using Web Services is a standard way for disparate corporate systems to exchange and update information and these services function much like simple web servers. However, unlike a simple web server, a Web Service communicates only through precisely defined XML documents for requests and responses.

Oracle Primavera Unifier offers an extensible interface platform based on XML Web Services to fully support interfacing with other customer systems. The interface provides Oracle Primavera Unifier with the ability to communicate with virtually any existing customer system.

As a result, information, business processes, workflows, budgets, internal transactions and any other data can be imported to/exported from Oracle Primavera Unifier via industry-standard Web Services. The benefits of the Oracle Primavera Unifier interface approach to integration are...

  • a fully extensible, standards-based XML Web services interface
  • secure and reliable data transfer
  • a customisable data transfer process
  • support for both data import and export
  • a flexible three-tier architecture
  • dynamic report generation

The Oracle Primavera Unifier solution is built upon a highly flexible three-tier architecture designed to support integration with a variety of external systems using industry-standard Web Services, based upon SOAP (Simple Object Access Protocol) standards and WSDL (Web Services Description Language). More importantly, Oracle Primavera Unifier Web Services support newly defined business processes and forms without the need for any programming.

If the system interfacing with Oracle Primavera Unifier has the ability to call Web Services, a direct integration can be built. Otherwise, a custom-developed Oracle Primavera Unifier client or enterprise application integration (EAI) with an enterprise service bus (ESB) can be used as an intermediary. To aid in the design of an interface, Oracle Primavera Unifier provides...

  • a publicised WSDL file that describes how to interact with Oracle Primavera Unifier Web Services
  • XML schemas that contain data mapping to Oracle Primavera Unifier data

Web Services utilise the same types of security measures used by many commercial websites to protect sensitive customer data exchanges, such as online banking or credit card transactions. The most important security feature is the Secure Sockets Layer (SSL) which controls data encryption. The Oracle Primavera Unifier Web Service interface requires that all connections be secured in the same way so that sensitive company data is protected.

Oracle Primavera Unifier Web Services are also dynamic because XML schemas are generated according to the client data fields to be integrated. Oracle Primavera Unifier also enables users to define reports that can be run via a Web Service and the results are returned in the response. This feature can be leveraged to get report-based business intelligence from the system.
