EXTENSIBILITY OF EMBEDDED DATABASE PROCEDURES

摘要

Disclosed herein are systems and methods facilitating extensions to software applications that access a database, and in particular to applications with embedded database procedures. In various embodiments, an extension anchor embedded in the application as well as one or more extensions implemented as database procedures are encapsulated in specially marked database-procedure methods.

主权项

1. A method comprising:
defining a host application including a method declared as a database procedure, and embedding an extension anchor within the method, the extension anchor having an associated extension interface; implementing one or more extensions as methods declared as database procedures in accordance with the extension interface; registering the one or more extensions in an extension register and selectively activating the one or more extensions; compiling the host application, whereby an extension dispatcher calling the selectively activated ones of the one or more extensions is created; and executing the compiled host application, whereby one or more database procedures defined within the extensions called by the extension dispatcher are created and executed in a database.
