Abstract: A continuous query identified by an archived relation of an application may be received. A physical query plan may be generated for the continuous query and/or a child operator plan may be identified. A buffer operator may be inserted between the child operator and its parent operator and/or the event information from the child operator may be stored in the buffer operator. A query operator may be identified in the physical query plan. It may be determined that the query operator identified in the physical query plan is a same type as a second query operator in a second continuous query concurrently executing. Further, a combined query plan may be generated based at least in part on the query operator identified in the physical query plan being the same type as the second query operator in the second continuous query.

Abstract: Described herein is an electric motor drive system, including at least one power phase line, an external controller configured to generate a drive signal and provide the drive signal to the at least one power phase line, and motor electronics. The motor electronics include at least one switch coupled between the at least one power phase line and at least one electric motor terminal, and an internal controller configured to cooperate with the external controller to perform an authentication process therebetween. The external controller is further configured to cause the at least one switch to electrically couple the at least one power phase line to the at least one electric motor terminal in response to success of the authentication process.

Abstract: Techniques for managing real-time business event analysis and monitoring are provided. In some examples, a logical request may be received at a business intelligence server configured with a continuous query service. Additionally, the continuous query service may be configured to translate the logical request into a physical request. Further, business intelligence information may be provided based at least in part on querying against an event data stream with a continuous query configured based at least in part on the physical request translated by the continuous query service.

Abstract: A method may include receiving a continuous query identified by an archived relation associated with an application. The method may also include generating a physical query plan. Additionally, the method may include constructing a structured query language (SQL) equivalent expression corresponding to an attribute utilized by the operator and/or constructing an output SQL expression for the identified operator based at least in part on the SQL equivalent expression. Additionally, the method may include constructing the archiver query for the identified operator based at least in part on the output SQL expression. Further, the method may include executing the archiver query to obtain a result set of data records related to the application and/or generating a snapshot output of one or more data values related to the application based at least in part on the result set of data records.

Abstract: Techniques for managing continuous queries that include subqueries are provided. In some examples, a continuous query that includes at least a subquery may be identified. Additionally, the subquery may be processed to obtain a first result or generate a logical subquery plan. Further, in some instances, the continuous query may then be processed based at least in part on the first result from the subquery or by merging a logical continuous query plan with the logical subquery plan. This may result in obtaining a second result via querying a data source with the continuous query that is based at least in part on the first result from the subquery and/or the merged plans.

Abstract: Techniques for generating a multidimensional forecast are provided. In one technique, multiple segments are generated, each comprising a different set of attribute values. For each segment, a set of prior content requests for the segment is determined based on historical data, a forecasted number of content requests is determined based on the set of prior content requests, and the forecasted number of content requests is stored in association with a set of attribute values corresponding to the segment. A request is received to forecast performance of a content delivery campaign based on a particular set of attribute values. In response to receiving the request, multiple segments that share the particular set of attribute values are identified. The forecasted number of content requests associated with each segment of the multiple segments are aggregated to generate aggregated performance data. A portion of the aggregated performance data is caused to be displayed.

Further, the query may be evaluated based at least in part on the data object and the historical data.
