A method of well planning in an automatic well planning system comprises the steps of: selecting one or more tasks in a task manager; verifying by a task dependency a proper order of the one or more tasks; retrieving by the task manager from a task base one or more sets of instructions associated with the one or more tasks selected in the task manager and verified by the task dependency; retrieving by the task manager from an access manager one or more sets of input data associated with the one or more sets of instructions retrieved by the task manager from the task base; verifying that each set of input data of the one or more sets of input data retrieved by the task manager from the access manager is received by a corresponding one of the one or more sets of instructions retrieved by the task manager from the task base; executing, by the task manager, the one or more sets of instructions and using, by the task manager, the one or more sets of input data during the executing step thereby generating a set of results; and recording or displaying, by a task view base, the set of results on a recorder or display device.

One embodiment of the present invention is a technique for optimizing a task graph that specifies multiple tasks and the dependencies between the specified tasks. When optimizing the task graph, the optimization engine performs multiple iterations of runtime optimization operations on the task graph. At each iteration, an optimized task graph is generated based on a different task aggregation topology. The optimized task graph is then compiled and executed. Runtime statistics related to the execution are collected, and, in subsequent iterations, the task graph is further optimized based on the collected statistics. Once the optimization process is complete, the most optimal task graph topology that was identified during the process is used to generate an optimized task graph for execution.

The invention discloses an ETL task dependence relationship detecting method and device. The method comprises the following steps: for each task of ETL, obtaining a data operating order contained in the task; analyzing the data operating order to obtaining a source table and a target table related to the task; according to the target table, a task attribute table and a task dependence relationship configuration table, obtaining a source table of direct dependence by the target table and a source table of indirect dependence by the target table; and traversing the source table related to the task, the source table of direct dependence and the source table of indirect dependence and marking the error types and optimizable types of all task dependence relationships related to the task according to a preset rule. With adoption of the method provided by the invention, actual task dependence relationships and a preset task dependence relationship are compared according to a preset rule so as to automatically discover erroneous and optimizable task dependence relationships, thus reducing the occurrence frequency of faults caused by task dependence problem, saving time for manual task dependence problem check by testing personnel and further achieving the effect of improving testing efficiency.
