Abstract: A query statement is received that requires at least one calculated attribute. Thereafter, a data flow graph is generated that includes a plurality of nodes for executing the query. At least one of the nodes corresponds to the at least one calculated attribute and has at least one level of child nodes. The data flow graph is generated by generating at least one filter for each of the nodes corresponding to the at least one calculated attribute and by pushing down the generated filters to a corresponding child node. Once the data flow graph is generated, execution of the query can be initiated using the generated data flow graph. Related apparatus, systems, techniques and articles are also described.

Abstract: A plurality of transactions are executed in a data storage application. Thereafter, log entries are sequentially stored according to the plurality of transactions in at least one log. Each log segment has a first globally unique identifier (GUID) uniquely identifying the log segment and includes a second GUID uniquely identifying an immediately preceding log segment in the sequence. In addition, the current position in the at least one log is stored along with the current log segment GUID together with data pages during data backup. Subsequently, a position in the at least one log from which to initiate replay of the log segments and a GUID for a corresponding log segment at the determined position at database recovery time is determined based on information stored during data backup. Replay of the log segments is then initiated starting at the determined position. Related apparatus, systems, techniques and articles are also described.

Abstract: Implementations are described for exception handling for collaborating process models. Once an error or other exception is determined during execution of a process model, a collaborating process model is determined to be notified. The collaborating process model and the process model may be executing in a collaborating orchestration engine and in an orchestration engine, respectively. Thus, the collaborating process model may be notified of the exception. Then, the execution of the collaborating process model within the collaborating orchestration engine may be at least partly suspended, and execution of the process model and the collaborating process model may later be resumed once the exception has been resolved.

Abstract: Multiple dropdowns on a graphical user interface (GUI) are dynamically linked at runtime. The dropdowns are associated with inter-related attributes of an object displayed on the GUI. The content of each dropdown includes a list of values of an attribute and is entirely or partially hidden until the dropdown is selected. The list of values of each dropdown are dynamically generated and rendered at runtime, using stored data that links the attributes to their parent attributes. The stored data can be dynamically updated to reflect currently-available attribute values and the relationship of the attributes.
