摘要:
Disclosed herein are systems and methods for the hot deployment of database procedures embedded in a host software application. In various example embodiments, the database procedures are encapsulated in specially marked methods of the host application, which, when called at runtime, cause the database procedures, and associated procedure stubs through which the database procedures are called, to be created in a database catalog and executed on the database server. When an embedded database procedure is modified in an application by one user during execution of that application by a second user, compilation of the modified database procedure may result in deletion of the original database procedure and/or associated procedure stub from the database, avoiding inconsistencies between database procedure versions during application execution by the second user.
摘要:
A mesh structure can be a type concept that extends internal tables or other data structures of a business programming languages (e.g., ABAP) by associations, as known from a data object meta-model. A mesh can include a set of operations, such as for example iteration via an iterator object and selection of instances expressed by a path language. A mesh structure can be optimized for read access and traversal, and can provide a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh data structure. Related methods, computer program products, and systems are described.
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.
摘要:
Methods and apparatus, including computer program products, are provided for implementing a cooperative model between an application and a database. In one aspect, there is provided a computer-implemented method. The method may include receiving from an application a command to perform an operation at a database; accessing metadata representative of the application; configuring, based on at least the metadata, a result of the operation; and sending the configured result to shared memory accessible by the application. Related apparatus, systems, methods, and articles are also described.

A system, computer program product and method of processing function calls in a distributed application environment are provided. A number of function calls for communication from a sending application to a receiving application are queued in a database. Dependencies among at least a portion of the function calls that are being queued are determined while the function calls are stored in the queues. A schedule of execution of the function calls is then generated based on the determined dependencies.

In one embodiment, a method includes defining a parent structure including an extension. A polymorphic structure is defined for the extension. The polymorphic structure is associated with a plurality of client specialization structures, each client specialization being associated with a client in a plurality of clients. During runtime by a computing device, the parent structure is generated with an extension to a client specialization structure associated with one of the plurality of clients where client specialization structures associated with other clients are not visible to the parent structure.
