    • An On-Line Analytic Processing (OLAP) system computes complex expressions and aggregations in queries by re-using and sharing subparts of the expressions and aggregations. A dependency generation phase performed by the OLAP system identifies dependencies among metrics based on the expressions, aggregations, and other metrics used by the metrics. An access plan generation phase performed by the OLAP system generates an access plan based on the identified dependencies, wherein the access plan ensures that expressions, aggregations, and metrics are computed before they are needed, and that required values and intermediate results are passed up a tree structure of the access plan until they are used or consumed by some operator. An operator assignment phase performed by the OLAP system generates operators based on the access plan, and also generates project list expressions, aggregations to be computed in each operator, and input and output tuple types for each operator.
    • 在线分析处理(OLAP)系统通过重新使用和共享表达式和聚合的子部分来计算查询中的复杂表达式和聚合。 由OLAP系统执行的依赖生成阶段根据度量使用的表达式,聚合和其他度量来识别度量之间的依赖关系。 由OLAP系统执行的访问计划生成阶段基于所识别的依赖关系生成访问计划,其中访问计划确保在需要之前计算表达式,聚合和度量,并且将所需的值和中间结果传递给 访问计划的树结构,直到某些操作员使用或消耗。 由OLAP系统执行的操作员分配阶段基于访问计划生成运算符,并且还生成项目列表表达式,要在每个运算符中计算的聚合以及每个运算符的输入和输出元组类型。

    • A business rule processing system automatically processes dynamic business rules in a content management system, allowing frequent updates to the business rules. The updates can be automatically adapted by the system without restarting the content management system. The system utilizes a stand-alone rule engine. Business logic is encoded as business rule definition files using a platform-independent language; the business rule definition files are stored in a central business rule repository. The business rules are managed and executed by the rules engine; the rules engine provides business rule processing services to other parts of the content management system. The system reduces development and maintenance cost, accelerates the business rule update cycle, and simplifies administration efforts.
    • 业务规则处理系统在内容管理系统中自动处理动态业务规则,允许频繁更新业务规则。 更新可以由系统自动调整,而无需重新启动内容管理系统。 该系统利用独立的规则引擎。 业务逻辑使用平台无关语言编码为业务规则定义文件; 业务规则定义文件存储在中央业务规则库中。 业务规则由规则引擎管理和执行; 规则引擎向内容管理系统的其他部分提供业务规则处理服务。 系统降低开发和维护成本,加快业务规则更新周期,简化管理工作。
