Abstract: A data collection system. A data input form receives data, and a message queue receives the data from the data input form, and temporarily manages the data until the data collection system can process the data. A temporary data storage temporarily stores the data received by the message queue while waiting for the data collection system to process the data. A transaction manager receives the data from the message queue and processes the data. A data logger logs the processing transactions of the transaction manager. A data loader receives the data from the transaction manager and prepares the data for storage. A data storage device receives the data from the data loader.

Abstract: A method for determining an up time of a multi-component tool having discrete elements, where the up time determination is based upon different processes that are to be accomplished in the multi-component tool. The discrete elements of the multi-component tool and the different processes to be accomplished in the multi-component tool are identified. Different tool states for the multi-component tool are determined by setting element states for each of the discrete elements of the multi-component tool. A first possible element state indicates that the discrete element is functional, and a second possible element state indicates that the discrete element is nonfunctional. Possible combinations of the element states of the discrete elements are identified as the different tool states of the multi-component tool.
