Abstract: A calculation engine is described that executes calculation scenarios comprising a plurality of calculation nodes that specify operations to be performed to execute the query. One of the nodes can be a semantic node that is used to modify the query for operations requiring special handling including handling of hierarchy views. Related apparatus, systems, methods, and articles are also described.

Abstract: A query is received by a database server from a remote application server that is associated with a calculation scenario that defines a data flow model including one or more calculation nodes including stacked multiproviders. Subsequently, the database server instantiates the calculation scenario and afterwards optimizes the calculation scenario. As part of the optimization, the calculation scenario is optimized by merging the two multiproviders. Thereafter, the operations defined by the calculation nodes of the optimized calculation scenario can be executed to result in a responsive data set. Next, the data set is provided to the application server by the database server.

Abstract translation: 来自远程应用服务器的数据库服务器接收到查询，该远程应用程序服务器与定义包括一个或多个计算节点（包括堆叠的多维数据集）的数据流模型的计算方案相关联。 随后，数据库服务器实例化计算方案，然后优化计算方案。 作为优化的一部分，通过合并两个多维数据集优化计算方案。 此后，可以执行由优化的计算场景的计算节点定义的操作以产生响应数据集。 接下来，由数据库服务器将数据集提供给应用服务器。

Abstract: Described herein includes finding and replacing, including automatically, at least one null value in a table for allowing processing of the table with an ABAP-based application. In some implementations, the null values are replaced with replacement values that are compatible with further processing of the data in the table. For example, a replacement value can be a string providing information or a value, such as for performing a calculation.
