- The current materialized views selection approaches are static, which greatly disobey dynamic nature of OLAP and DSS. 然而现有支持物化视图自动选择的方法是静态的，它违背了联机分析处理(OLAP)和决策支持系统(DSS)的动态本质。
- In this paper, we use directed-acyclic graph (DAG) to represent a query processing, then define a cost model and a query efficiency model, and finally put forward an algorithm for materialized views selection. 在考虑空间约束的基础上，提出一种物化视图选择方法，并给出了切实可行的算法步骤。
- This paper firstly presents a materialized view selection algorithm, which selects views to materialize based on the minimal ancestor tree and implements with an improved heuristic strategy. 提出利用最小祖先树筛选视图,并结合改进的试探式策略进行物化视图选择的算法。
- Preprocessor of Materialized Views Selection 物化视图选择的预处理算法
- PBC:A Materialized Views Selection Algorithm 实例化视图选择算法PBC
- The Research on Materialization View Selection Method of Spatial Data Cube 空间数据立方体的物化视图选择方法研究
- materialized view selection 物化视图选择
- This paper gives an cost model of materialized view.Materialized view selection algorithm and strategy using genetic rules are presented. 论文给出实视图代价估算模型,利用遗传规则,提出实视图选取的方法和策略。
- The optimizer transparently rewrites the request to use the materialized view. 优化器明显的利用物化视图重写其请求。
- SCRIPT_TYPE STATEMENTIMPLEMENTATION CREATE MATERIALIZED VIEW LOGON "ARUP". 你怎么才能知道已为这个物化视图创建了其正常工作所必需的所有对象？
- The basic idea was to take a materialistic view of human nature. 此想法的基本概念，就是以唯物主义的观点看待人性。
- The expression defining the computed column can have the same form as a more complex expression in the view select list. 定义计算列的表达式可与视图选择列表中的较复杂表达式具有相同的形式。
- The radical database will update when the information source change and can incite the materialized view to update and maintain. 当信息源发生变化时,基库随着更新,同时触发多实化视图的更新与维护。
- A materialized view can be partitioned. You can define a materialized view on a partitioned table and one or more indexes on the materialized view. 一个物化视图可以被分割。你能定义一个物化视图在一个分割表，也能定义在物化视图的一个或多个索引上。
- Unlike indexes, materialized views can be accessed directly using a SELECT statement. 不同于索引，物化视图可以使用SELECT语句直接访问。
- RESERVATIONS.HOTEL_ID GROUP BY ARUP.RESERVATIONS.CUST_NAME, ARUP.RESERVATIONS.RESV_ID, ARUP.HOTELS.CITY UNDO DROP MATERIALIZED VIEW ARUP. 相反，需要对每一个物化视图的结构进行目视检查，这是非常不实际的。
- "RESERVATIONS" WITHROWID, SEQUENCE ("RESV_ID","HOTEL_ID","CUST_NAME")INCLUDING NEW VALUESIMPLEMENTATION ALTER MATERIALIZED VIEW LOG FORCE ON "ARUP". 相反，需要对每一个物化视图的结构进行目视检查，这是非常不实际的。
- Select the View Selected Addresses link to view a list of the addresses you have marked for deletion. 选取检视选择的地址连结以查看您标明要删除的地址列表。
