摘要： A communications system having a data transfer pipeline apparatus for transferring data in a sequence of N stages from an origination device to a destination device. The apparatus comprises dedicated memory having buffers dedicated for carrying data and a master control for registering and controlling processes associated with the apparatus for participation in the N stage data transfer sequence. The processes include a first stage process for initiating the data transfer and a last Nth stage process for completing data transfer. The first stage process allocates a buffer from a predetermined number of buffers available within the memory for collection, processing, and sending of the data from the origination device to a next stage process. The Nth stage process receives a buffer allocated to the first stage process from the (N−1)th stage and to free the buffer upon processing completion to permit reallocation of the buffer.

摘要： There is disclosed in a communications system having an origination storage device and a destination storage device, a data transfer pipeline apparatus for transferring data in a sequence of N stages, where N is a positive integer grater than 1, from the origination to the destination device. The data transfer apparatus comprises dedicated memory means having a predetermined number of buffers dedicated for carrying data associated with the transfer of data from the origination storage device to the destination device; and master control means for registering and controlling processes associated with the data transfer apparatus for participation in the N stage data transfer sequence. The processes include at least a first stage process for initiating the data transfer and a last Nth stage process for completing data transfer. The first stage process is operative to allocate a buffer from the predetermined number of buffers available within the dedicated memory means for collection, processing, and sending of the data from the origination device to a next stage process. The Nth stage process is operative to receive a buffer allocated to the first stage process from the (N−1)th stage process in the data transfer sequence and to free the buffer upon processing completion and storage in the destination device to permit reallocation of the buffer. The master control means further includes monitor means for monitoring the number of buffers from the pool of buffers allocated or assigned to particular processes in the pipeline, in order to prevent allocation of further buffers to a particular process when the number of buffers currently allocated exceeds a predetermined threshold.

摘要： A storage and data management system establishes a data transfer pipeline between an application and a storage media using a source data mover and a destination data mover. The data movers are modular software entities which compartmentalize the differences between operating systems and media types. In addition, they independently interact to perform encryption, compression, etc., based on the content of a file as it is being communicated through the pipeline. Headers and chunking of data occurs when beneficial without the application ever having to be aware. Faster access times and storage mapping offer enhanced user interaction.

摘要： Data constructs and architectures are disclosed for providing a foundation for an application-building system for enabling a non-technical user to perform discrete tasks to build a complete network-based application and maintain the same user experience throughout the application development. A data model having an extensible underlying structure that can be used in a user-oriented application development system having a task-based architecture is defined. The data model is capable of allowing for extensible attributes such that the addition of a new data attribute can be made without changing the underlying structure of the data model. Multiple applications making up the user-oriented application development system can access data from the data model. Data stored in a database having the data model as an underlying structure can be reused by the task-based architecture for various applications.
