IBM Streams 4.3.0
Overview of the Commodity Purchasing sample application
The
Commodity Purchasing sample application processes live data streams and makes real-time
decisions to illustrate the nature of stream processing applications.
The application is designed to run in a basic environment. It does
not attempt to demonstrate the scalability or low latency that can
be achieved by using IBM®
Streams.
The Commodity Purchasing sample application is used by analysts
to help them make commodity purchasing decisions. The application
provides the following information:
- Identifies the best supplier to purchase from at any point in time, taking into account both quality and risk-management considerations.
- Looks for opportunities to buy Infoberries (a fictitious commodity) of especially fine quality, and automatically purchases them.
- Monitors for supply levels that are critically low and automatically buys more Infoberries from the best current supplier.
The following graphic shows a breakdown of the different parts
of the Commodity Purchasing sample application. The application consists
of the following parts:
- Multiple data sources.
- A streams processing application that is written in the IBM Streams Processing Language (SPL).
- Multiple data sinks.
- A browser-based application user interface.
