An efficient reusable, extensible light weight framework statelessly orchestrates system activities in any application which involves a series of sequential or parallel set of activities involving computational logic, data retrieval and persistence services. Actual orchestration steps and activities and computational logic are specified into configuration files, separate from the orchestration engine itself, thereby eliminating the need to code for such logic and activities. The framework can eliminate the need to code business logic and orchestration of data retrieval services by externalizing them into configuration files, resulting in lower costs to implement, test and maintain such system during its lifespan.
