US Classification:

707716, 707741

Abstract:

Provided is a technique for building an index. A new indexis built and an anchor text tableand a duplicates tableare output using a store, a delta store, and previously generated global analysis computations, wherein the previously generated global analysis computationsinclude an anchor text table, a rank table, and a duplicates table. New global analysis computationsare generated using the anchor text tablei+1, the duplicates table, and the previously generated global analysis computations.

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.

International Classification:

G06F 17/30
G06F 9/44

US Classification:

707736, 719328

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.

US Classification:

707758, 707E17014, 707E17017

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.
