  • Method and combination for minimizing data conversions when data is transferred between a first database storing data in a first format and a second database storing data in a second format
    Patent number: 5566332
    Abstract: The invention establishes the context in which data exchanged between dissimilar relational database management systems can be mutually understood and preserved, and data conversions can be minimized. 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. Any data conversions that may be necessary are done only by the receiver of the data, and only at the point where it is necessary to have the data represented in the receiver's native format for processing.
    Type: Grant

  • Heterogenous database communication system in which communicating systems identify themselves and convert any requests/responses into their own data format

  • Query language execution on heterogeneous database servers using a bind-file bridge between application and database languages
    Patent number: 5257366
    Abstract: Application programs which are developed and scheduled within a first computing system environment are permitted to access relational data registered at a remote database management system (DBMS) operating in a second computing environment dissimilar to the first computing environment. Access to data through the DBMS from an application execution site remote from the DBMS is supported by a process, logically subordinate to the application program which maps application program data access requests to the DBMS.
