摘要： A method of maintaining a data store is disclosed. The data store is distributed across a plurality of storage provider instances, including a master storage provider instance and a plurality of additional storage provider instances. A master data log is updated to reflect a change to the data store. The master data log is synchronized with a plurality of replicas of the master data log. The change is propagated across the plurality of additional storage provider instances based on an analysis of the replicas.

摘要： Automatic management of networked publisher-subscriber relationships in an advertising server network. The method comprises steps for constructing a directed graph representation comprising at least one publisher node (e.g. an Internet property), at least one subscriber node (e.g. an Internet advertiser), at least one intermediary node (e.g. an Internet advertising agent), and at least one edge (e.g. an advertising target predicate) wherein any one of the edges is directly associated with at least one target predicate. The directed graph representation is used in conjunction with an inverted index for retrieving a valid node list comprising only nodes having at least one target predicate that matches at least one event predicate. The event predicate (as well as any target predicate) is any arbitrarily complex Boolean expression, and is used in producing a result node list comprising only nodes that concurrently match the event predicate with an advertising target predicate and are reachable.

摘要： A modeling system to evaluate cost-based viability of a real-time, auction-based advertising system with third-party integration includes an exchange server configured to receive advertising bids, create bid requests to third-party entities based thereon, and select a winning bid from responses to the requests. A computer, coupled with the exchange server: computes a plurality of valid paths from publishers to and from the third-party entities through the exchange server; estimates server and network costs, including fixed hardware costs and variable operational costs, amortized over a predetermined period of time, based on a number of average queries per second (QPS) transmitted at different portions of the valid paths; compares current periodic fees paid by the third-party entities to the amortized costs, to determine cost-based system viability; and determines updates, if needed, to the periodic fees based on the plurality of costs to maintain cost-based system viability.

摘要： An online advertising system integrates third party agents to permit the third party agents to participate in auctions to bid on a per opportunity basis. An advertising exchange module receives requests for opportunities to serve online advertisements to users. In response, an advertising exchange module applies one or more business rules to determine third party agents that qualify to serve the online advertisement. A bid gateway module generates and transmits requests for bids to the third party agents. The bid gateway module then receives bids from the third party agents in response to the requests for bids. The advertising exchange module then selects an advertisement based on the bid. The online advertisement exchange system provides a unified marketplace to permit integrator networks to bid on both ads pursuant to guaranteed contracts and ads not subject to guaranteed contracts (e.g., non-guaranteed ads). The online advertisement system further includes traffic management to allow the third parties to regulate bid requests sent from the online advertisement system. In some embodiments, the online advertising system caches bids, to efficiently implement the per opportunity auction, and transmits information, such as targeting information, to the third party agents to aid in the third party agents' formulation of bids.

摘要： Various techniques are described for processing database commands that include MINUS and/or INTERSECT operators. The queries containing the MINUS and/or INTERSECT operators are transformed to create a plurality of transformed queries. Each of the transformed queries produces the same result as the original query, but does not include the MINUS and/or INTERSECT operator. To achieve the same result set as the original query, the transformed queries employ equijoins, antijoins, and/or semijoins, and duplicate elimination operations. Costs are estimated for each of the various transformed queries. Based on the cost estimates, one of the transformed queries is selected as the query that is to be executed to perform the operations specified in the original query.

摘要： A database statement is processed in a multi-server system, in a manner to increase the possibility that slave server processes on remote nodes will generate execution plans that are equivalent to the corresponding execution plan generated by the query coordinator process. A set of hints is generated based on the same information on which the master plan is based. The set of hints is sent to remote nodes, where respective remote plans are generated based in part on the set of hints. Use of the hints in generation of the remote plan increases the possibility that the remote plan will be equivalent to the master plan and that the slaves on the other database server will be able to join in parallel processing of the database statement.

摘要： Techniques are provided for processing, within a database server, a database statement, where at least one subtask required by the database statement is to be executed in parallel by a slave set. The database server determines whether the database statement includes an external expression, relative to the subtask, that (a) produces information that is required by slave processes in the slave set in order to perform the subtask, and (b) is not to be evaluated by each slave process in the slave set. During execution of the statement, if the database statement includes an external expression, then one or more external values are generated by causing the external expression to be evaluated, and the one or more external values are communicated to slaves of the slave set to allow the slave processes to perform respective portions of the subtask in parallel, without requiring each slave of the slave set to evaluate the external expression.
摘要翻译：提供技术来在数据库服务器内处理数据库语句，数据库语句所要求的至少一个子任务将由从属集并行执行。数据库服务器确定数据库语句是否包含相对于子任务的外部表达式，（a）产生从属集中的从属进程所需的信息以执行子任务，并且（b）不被评估由从设备中的每个从属进程。在执行语句期间，如果数据库语句包含外部表达式，则通过使外部表达式进行求值来生成一个或多个外部值，并将一个或多个外部值传送到从设备的从站，以允许从属进程并行执行子任务的各个部分，而不需要从属集的每个从属点来评估外部表达式。

摘要： A method and apparatus is disclosed for allowing access to one or more previously generated rows of data. A server receives a statement that requires delivery of one or more rows of data to a client, and designates a particular row of data as a current row within a generation sequence. As the rows of data are being delivered to the client, the server accesses select previously generated rows of data that has already been delivered to the client without designating a new particular row of data as the current row. Once the previously generated row is accessed, data is retrieved from predetermined columns. The data retrieved may be used to perform various calculations that will insert values into the current row prior to delivery of the current row to the client. The statement transmitted by the client may include various parameters, including a default parameter, that specifies a default value to be used by the server. The previously generated row is then retrieved based on an offset parameter specified by the client. If the location determined is outside a predetermined range of addressable rows in the generation sequence, then the default value specified by the default parameter is returned. The present invention may also be configured to use a buffer and manage dynamic memory allocated to the buffer.
摘要翻译：公开了一种用于允许访问一个或多个先前生成的数据行的方法和装置。服务器接收需要将一行或多行数据传送给客户端的语句，并将特定行数据指定为生成序列中的当前行。当数据行被传递到客户端时，服务器访问已经传递给客户端的先前生成的数据行，而不指定新的特定数据行作为当前行。一旦访问了先前生成的行，就从预定的列中检索数据。检索的数据可用于执行各种计算，这些计算将在将当前行传递给客户端之前将值插入到当前行中。客户端发送的语句可以包括指定服务器使用的默认值的各种参数，包括默认参数。然后根据客户端指定的偏移参数检索先前生成的行。如果确定的位置在生成序列中的可寻址行的预定范围之外，则返回由默认参数指定的默认值。本发明还可以被配置为使用缓冲器并管理分配给缓冲器的动态存储器。
