Abstract: The invention relates to a system including a first database management system for managing a database (40) including data having a first data format and a second database management system for managing a database (50) including data having a second data format. The invention is a method for converting data transmitted between the first and second database management systems, the method including the steps of sending from the first to the second database management system a command containing data in a data format native to the first database management system; and at the second database management system, converting the data in the command into a data format native to the second database management system.

Abstract: The invention establishes the context in which data exchanged between dissimilar relational database management systems can be mutually understood and preserved. The invention accomplishes this by establishing layers of descriptive information which isolate machine characteristics, levels of support software, and user data descriptions. Optimized processing is achieved by processing the different descriptor levels at different times during the development and execution of the database management systems. Minimal descriptive information is exchanged between the cooperating database management systems. For systems which match, data conversion is completely avoided. For systems which do not match, data conversion is minimized.

Abstract: A method of selectively communicating data between users in a communication system comprising the steps of: assigning a local user identifier to each user of said system; transmitting the local user identifier of a calling user to a called user; comparing the local user identifier of the calling user with at least one identifier of a predetermined remote user assigned to the called user; and if the comparison is positive, transmit the local user identifier of the called user to the calling user to establish an exchange of data between said called user and said calling user.

Abstract: A data communications system for asynchronous communication having at least two data transmit/receive terminals (50) wherein the display (42) is periodically updated with new send or receive data. In the receive mode the data is accumulated in a receive buffer (72) for a predetermined time interval and then transferred into a text storage buffer (80) which then activates a display access method (86) to process the stored data and update the display. The display access method (86) then goes into an "idle" mode and waits for the next transfer of data which does not occur until the predetermined time interval has expired. In the transmit mode the send data is transmitted without a delay but the display is updated after the predetermined time interval has expired.

Abstract: The invention provides transaction synchronization in the form of COMMIT process ing in a distributed, heterogeneous database system wherein some resources are synchroniz ed to a transaction by a single-phase commit procedures while other resources synchronize by multi-phase commit procedures. The invention invests an application requestor at an application site with authority to represent all single-phase commit resources in multi-phase commit processing.
