摘要： A grouping mechanism is provided which can return distinct groups of entries of data that satisfy a users query in a non-blocking fashion. Each distinct group can normaly be returned to the user substantially concurrently with the following entries being received and processed. The grouping mechanism supports an overflow mechanism which can transfer parts of the data between a primary memory to a secondary memory to alleviate shortage of primary memory. This non-blocking mechanism is useful as a part of a dataflow model data processing system.

摘要： A method for executing after-triggers in an active database. A tree is constructed for each after-trigger and an operator tree is constructed for the statement that activates the trigger. The method joins each of the trees for the activated row-after triggers to the operator tree for pipelined execution with the operator tree. The trees for the activated row-after triggers form a group and each of the trees within the group execute in parallel with each other. The method joins trees for activated statement-after triggers to the operator tree for execution subsequent to the execution of the operator tree, the statement after trigger trees receiving rows from a temporary table that accumulates affected rows from the operator tree. Trees for activated statement after triggers form a group and each of the trees within the group execute in parallel with each other.

摘要翻译： 一种在活动数据库中执行后触发器的方法。 为每个后触发构建一个树，并为为激活触发器的语句构建一个操作符树。 该方法将激活的逐行触发器的每个树连接到运算符树，以便使用运算符树进行流水线执行。 激活的行后触发器的树形成一个组，组中的每个树彼此并行执行。 该方法将激活的语句后触发器的树连接到运算符树，以便在执行操作符树之后执行该语句，触发树之后的语句从临时表接收来自运算符树的受影响行的行。 触发后激活语句的树形成一个组，组中的每个树彼此并行执行。
