    摘要： A method and apparatus for updating a segmented bitmapped index to reflect a change made to data upon which the segmented index is based. Change records specifying changes to bitmap segments contained in the segmented bitmapped index are sorted by key value (bitmap segment) and row ID (bit) before being applied to the segmented bitmapped index. When the change records are being applied to the bitmap segment contained in the segmented bitmapped index, the index entry containing the bitmap segment to be updated is locked. If a new bitmap segment must be generated, the index entry covering a row in the data having a row ID less than the row ID of the change is first locked. Then a new index entry is generated, stored in the segmented bitmapped index, and the locked index entry unlocked. If the segmented bitmapped index does not contain an index entry covering a row in the data having a row ID less than the row ID of the change, then a dummy index entry is generated, stored in the segmented bitmapped index, and locked. A new index entry is then generated and stored in the segmented bitmapped index, after which the dummy index entry is unlocked and deleted.

    摘要翻译： 一种用于更新分段位图索引以反映对分段索引所依据的数据所做的改变的方法和装置。 包含在分段位图索引中的位图段的更改的更改记录在应用于分段位图索引之前按键值（位图段）和行ID（位）进行排序。 当更改记录被应用于包含在分段位图索引中的位图片段时，包含要更新的位图片段的索引条目被锁定。 如果必须生成新的位图段，则首先锁定具有小于更改行ID的行ID的数据中包含行的索引条目。 然后生成新的索引条目，存储在分段位图索引中，并锁定索引条目。 如果分段位图索引不包含覆盖具有小于该变化的行ID的行ID的数据中的行的索引条目，则生成虚拟索引条目，存储在分段位图索引中并被锁定。 然后生成新的索引条目并将其存储在分段位图索引中，之后解锁和删除虚拟索引条目。

    摘要： The present invention performs parallel processing of aggregate functions in a computing system. Partitioned into multiple subsets of data and each of the multiple subsets of data is allocated to one of a plurality of processes. Intermediate aggregations are performed in parallel by the plurality of processes on each of the multiple subsets of data. Each intermediate aggregation yields at least one intermediate value, wherein the at least one intermediate value is represented in an internal type format. The intermediate values from each of the intermediate aggregations are merged into a final aggregation value.

    摘要： Viruses having weakened ability to establish and/or maintain latency and their use as live vaccines are described. The vaccines have one or more alterations in genes that provide continued virus replication but that inhibit latency. The vaccine materials and methods for their construction are exemplified with the varicella zoster virus. Deletion of a significant portion from both copies of the varicella zoster gene ORF63 was shown to inhibit establishment of a latent infection from a live vaccine form of the virus. Insertion of an additional ORF62 gene which is partially truncated with the ORF63 deletion inhibited establishment of latency and allowed normal growth of the virus. Other desirable viral antigen encoding sequence(s) and/or cytokine genes advantageously may replace deleted genetic material to enhance a desired immunological response. Aspects of the discovery pertain to live vaccines of other viruses, and can provide a variety of vaccines having greater safety.
