Oracle E-Business Suite addresses business-to-business (B2B) and business-to-consumer (B2C) sales, marketing, analysis, and service needs through the Internet. Oracle E-Business Suite consists of front-office Customer Relationship Management (CRM) applications and back-office Enterprise Resource Planning (ERP) applications. These applications automate marketing, sales, contracts, service, manufacturing, and supply chain processes. They also automate financial operations, project management, human resource operations, and business intelligence systems.

Oracle E-Business Suite has a three-tier architecture. It includes the desktop tier, application tier, and database tier.

A tier is a logical grouping of services that can be spread across more than one physical machine. The desktop tier provides the user interface through an add-on component to a standard Web browser. The application tier supports and manages various application components. It hosts servers that process the business logic. It also manages communication between the desktop tier and the database tier. The database tier supports and manages the Oracle database.

PowerExchange for Oracle E-Business Suite interacts with the database tier to extract metadata and data. When the PowerExchange for Oracle E-Business Suite loads data to Oracle E-Business Suite, it interacts with the database tier and the Concurrent Processing Server component of the application tier.

PowerExchange for Oracle E-Business Suite submits a request to the Oracle E-Business Suite concurrent manager to run a concurrent program, which initiates the data loading from the open interface tables to the Oracle E-Business Suite tables. A concurrent program validates the data before loading it to the internal tables. Each open interface has an associated concurrent program.
