    Abstract: Database objects, having interdependent relationships, are transferred for replication from a publisher to a subscriber in the order of a topological sort using a depth first search algorithm. When the depth first search algorithm attempts to enumerate all outgoing edges (dependencies) of a given node (database object), a request is made to begin an atomic transaction and then a temporary copy (e.g., via a T-SQL command) of the node/database object is created under a different name. The temporary copy is used to store dependency information that could otherwise be impaired by the replication process. Dependencies amongst database objects are thus preserved during the replication process through use of the temporary copy, as well as by transferring the database objects according to the topological sort order.

    Abstract translation: 具有相互依赖关系的数据库对象以使用深度优先搜索算法的拓扑排序的顺序被传送以从发布者到订阅者进行复制。 当深度第一搜索算法尝试枚举给定节点(数据库对象)的所有传出边(依赖关系)时,请求开始原子事务,然后进行临时拷贝(例如,经由T-SQL命令) 以不同的名称创建节点/数据库对象。 临时副本用于存储否则会被复制过程损害的依赖关系信息。 因此,在复制过程中,通过使用临时副本以及根据拓扑排序顺序传输数据库对象,可以保持数据库对象之间的依赖关系。

    Abstract: A method and apparatus for selecting a subset of advertisements complying with an advertisement request from a set of advertisements is disclosed. Advertisements rules are specified according to a logical semantic simplifying search combinatorials yet allowing for flexible specification of advertising rules, and permitting significant precomputation of advertising rules to permit rapid identification of advertisements complying with advertisement requests. In one embodiment, advertisement rules and requests are represented as easily manipulable and computable bit arrays.
