1. A middleware system for managing workflows among computer applications, the system comprising: a common construct unit for retrieving a mapping between a component of a macro workflow of the middleware system and a micro workflow component of a plurality of computer applications and for executing the macro workflow, wherein the macro workflow orchestrates a plurality of micro workflows of the plurality of first computer applications, wherein the macro workflow includes a series of steps, each step being one of the plurality of micro workflows, and wherein each of the plurality of micro workflows is performed by one of the plurality of computer applications, wherein the common construct unit comprises a service manager component for: testing an existing connection between the middleware system and at least one of the plurality of computer applications, and creating a new connection between the middleware system and at least one of the plurality of computer applications; and a workflow export unit for generating an output that enables the common construct to execute the macro workflow by executing at least one of the plurality of micro workflows on one of a plurality of similar computer applications.
