【摘要】 本文在分析了现有数据采集方法基础上,提出一种用于分布式异构数据库搜索的数据采集模型。该模型采用ETL数据集成技术,并将广泛应用于企业资源管理的LDAP目录服务引入数据采集模型中,利用LDAP存储和管理描述数据源信息和采集规则的元数据,增强了数据集成的可扩展性和自动化程度。更多还原

【Abstract】 Under the analysis of the current integration methods,a novel data collection model for distributed heterogeneous database search engine is proposed.It applies ETL and LDAP which is widely used by enterprise for application resource management,uses matadata to describe the data source information and data extraction rules,and reserves them to LDAP.This model increases the ex-tensibility and automaticity of integration.更多还原
