ABSTRACT:
A multitask multiuser system provides for efficient transfer of data from a remote data base to individual subscribers and has particular utility in the distribution of stock market data. A primary provider distributes the incoming data directly to user tasks or to an inquiry provider or a monitor provider. The inquiry provider responds to specific inquiries by users for information in the data base. The monitor provider maintains lists of information which are being monitored by the host computer for individual users. The inquiry provider and the monitor provider do not repeat requests to the remote data base where a similar request is already pending from another user. Data transfer paths between tasks are estabilished by a code module which may be linked to any of the tasks. The transfer paths are established using information from a configuration list and they are monitored by the operating system through a wait list established for each user task. Providers in the system may establish subscriber lists through the code module.
