Abstract

A system and method are provided for providing base service patterns for use in a component-based architecture. A batch job pattern is provided for structuring batch components such that common architectural services are implemented uniformly across the batch components. A batch unit of work pattern is utilized for structuring work to be processed by the batch components so that the work is treated uniformly by the batch components. A processing pipeline pattern is implemented for structuring batch activities for simplified reconfiguration of the batch activities, including preparing to perform a series of processing steps on input objects, encapsulating each of the processing steps within a filter, receiving and processing the input objects in one of filters; delivering results from the filters incrementally during processing of the input objects, utilizing connectors for connecting at least two of the plurality of filters, and using connectors for connecting input and output filters of different processes for forming a scalable system. An abstraction factory is used to encapsulate differences between objects such that only activities that need to understand the difference between the objects have to deal with the differences.
