PetroVantage (PV) is a web-based solution that is either resident within a client’s firewall or deployed through a centrally-hosted site. PV components communicate using XML interfaces. For inter machine communication, PV deploys secure HTTP (HTTPS). For in-process communications, Java Beans and regular function calls passing XML data arguments are deployed.
PV system architecture consists of the following tiers—
1) Presentation layer—end user accesses PV using Microsoft Internet Explorer 5.5 or higher with 128-bit browser encryption.
2) Business Logic layer—IBM Web Sphere Application Servers host the Business Logic layer.
3) Persistence layer—PV supports SQL 2000 or Oracle RDBMS.
Current deployment uses a hosted Storage Area Network (SAN) from EMC. The Business-to-Business (B2B) layer leverages webMethods (or any message-based system such as TIBCO) to provide interoperability and data integration with third-party systems, such as SAP or legacy tools.
PV has been completely developed in Java and is J2EE compliant. It is tested and commercially deployed on Windows 2000 server, but has not been tested on UNIX. PV supports IBM Websphere and BEA Weblogic. PV has been tested and commercially deployed on the IBM WebSphere 3.52 release.
