CODELESS INFORMATION SERVICE FOR ABSTRACT RETRIEVAL OF DISPARATE DATA

摘要

An abstraction engine receives requests identifying a source application and a logical identifier and maps the request attributes to a stored procedure. The stored procedure invokes a native database call with respect to a database and returns the response to the abstraction later, which reformats the response to an object having key, value pairs that is independent of the database protocol or organization. Stored procedures may be mapped to various combinations of attributes of requests, which may include attributes such as a user identifier and application version. The stored procedure may return data from a particular database location or perform more complex functions such as filtering functions with using predefined filer criteria and locations or a filtering criteria and/or location derived from the request.
