Abstract: A system includes reception of a first request for a lock on a lock object, storage of a first entry associated with the first request and the lock object in a queue, determination of a first queue position associated with the first entry based on a first priority level of the first request and on a priority level of each of a plurality of entries in the queue associated with the lock object, determination of whether a predetermined expiration time associated with the first request has expired, and, if it is determined that the predetermined expiration time has expired, deletion of the first entry from the queue.

Abstract: The disclosure generally describes computer-implemented methods, software, and systems for allowing provisioning of open data protocol (OData) services on top of a generic interaction layer (GenIL). One computer-implemented method includes receiving an OData-compliant request for data, determining a GenIL data provider to receive the OData-compliant request for data, determining the memory location of the data, requesting the data from the determined memory location, receiving the requested data from the determined memory location, converting, using at least one computer, the received data into an OData-compliant format, rendering an OData-compliant response, and transmitting the OData-compliant response.

Abstract: Described herein is a framework for providing data model views with complex calculation capability. In accordance with one aspect, the framework receives a request to calculate target results. An object in an application layer may be invoked to perform complex calculation to generate intermediate results. The intermediate results are stored in a global temporary table. A data model view in a database layer may then be invoked to calculate the target results based on the intermediate results retrieved from the global temporary table. The calculated target results are then returned.

Abstract: A system includes reception of a first instruction at a first system to effect a first change to a hierarchy data model, storage of a first record including first values specifying the first change in a local memory of the first system, reception of a second instruction to effect a second change to the hierarchy data model, storage of a second record including second values specifying the second change in the local memory of the first computer system, reception of an instruction to save the changed hierarchy data model, and, in response to the instruction, transmit the first record and the second record to a second system. The first record and the second record are received and merged to generate a third record including third values specifying a third change to the hierarchy data model, and a query language statement is generated to effect the third change to the hierarchy data model based on the third record.

Abstract: An indirect data object association module performs an indirect data object association based on detecting a user interaction with an interface for determining data objects associated with a selected data object. The module generates a direct association interface object that lists data objects directly associated with the selected data object and accesses data corresponding to data objects associated with the data objects listed in the direct association interface object. An indirect data object association is performed based on the selected data object, its directly associated data objects and the accessed data. The module generates an indirect association interface object to list data objects indirectly associated with the selected data object and links the indirect association interface object to the direct association interface object. A periodic indirect data object association report is generated for multiple data objects based on respective indirect association interface objects for each of the multiple data objects.
