    • A semantic publish/subscribe system enables semantic event routing and allows publishers (resp. subscribers) to use self-defined event schemas to publish (resp. subscribe) events. The constraints on value-based publish/subscribe systems that publishers and subscribers must share the same event schemas are removed. With ontology support, the system conducts event correlation based on their semantics using relational operators. Event sources are searched for subscriptions and selected events are automatically correlated according to subscriptions. The system enables efficient semantic event routing by rewriting the subscription SQL statement, wherein no redundant events are generated.
    • 语义发布/订阅系统启用语义事件路由,并允许发布者(分别订阅者)使用自定义事件模式来发布(或者预订)事件。 发布商和订阅者必须共享相同事件模式的基于价值的发布/订阅系统的限制将被删除。 通过本体支持,系统使用关系运算符根据其语义进行事件关联。 搜索订阅的事件源,并根据订阅自动关联选定的事件。 该系统通过重写订阅SQL语句来实现有效的语义事件路由,其中​​不生成冗余事件。

    • A technique for efficiently joining multiple large tables in a database system which utilizes a join index. The technique uses a join index and minimizes the number of input/output operations while maximizing the use of the small main memory through a buffer allocation process based on the join index entries. The technique uses multi-dimensional partitioning and assigns partition identifiers to each buffer which are used to coordinate the resultant output files when the technique is complete. The output is vertically fragmented with one fragment for each input table which further allows the individual processing of each input table. The technique performs self-joins in a very efficient manner by requiring the records of the input table to be read only once.
    • 一种利用连接索引的数据库系统中有效连接多个大表的技术。 该技术使用连接索引并且最小化输入/输出操作的数量,同时通过基于连接索引条目的缓冲器分配过程最大化使用小主存储器。 该技术使用多维分区,并为每个缓冲区分配标识符,用于在技术完成时协调结果输出文件。 输出垂直分段,每个输入表有一个片段,进一步允许每个输入表的单独处理。 该技术通过要求输入表的记录只读一次,以非常有效的方式执行自联接。
