  • Patent number: 10360211
    Abstract: According to one embodiment of the present invention, a system enables control of database applications. The system comprises a computer system including a database application to provide access to a database system, and at least one processor. The computer system requests retrieval of application specific property information for the database application from a data repository, and applies the retrieved application specific property information to the database application to control operation of the database application. Embodiments of the present invention further include a method and computer program product for controlling database applications in substantially the same manner described above.

  • Patent number: 10013331
    Abstract: Provided are techniques for invoking with a processor executing on a computer a source code parser to obtain source information that includes a first location of an Application Programming Interface (API) call and parameters of the API call in source code of a client application, where the parameters the API call do not include query text for a query that is to be used to access a database; examining a stack trace to determine a second location of the API call in the stack trace; and deriving the query of the API call and a third location of the query in the source code by identifying the query in the stack trace at the location of the API call in the stack trace.

  • Patent number: 8868617
    Abstract: A system and method for connection of an application program to its corresponding database in a relational database system environment. Rather than embedding connection configuration information or properties in an application program, connection configurations are stored in a connection configuration repository. The connection configuration repository is likewise stored in a database within the relational database system environment. The connection configuration information stored in the configuration repository may be updated, revised, deleted or assembled into groups/subgroups, without affecting the application programs.

  • Patent number: 8499281
    Abstract: A technique is disclosed for identifying impact of database changes on an application. Given a proposed database change, affected source code is identified that is affected by the proposed database change. References to the affected source code are created and organized into a hierarchy. A user can ascertain the extent of the impact by viewing the hierarchy and by using the hierarchy to access and view the affected source code in a visually distinct manner.
