15 صفحه اولExtending ETL framework using service oriented architecture
Extraction, Transformation and Loading (ETL) represent a big portion of a data warehouse project. Complexity of components extensibility is a main problem in the ETL area, because ETL components are tightly-coupled to each others in the current ETL framework. The missing extensibility feature causes impediments to add new components to the current ETL framework; to meet special business needs. ...
متن کاملPolicy-Regulated Management of ETL Evolution
In this paper, we discuss the problem of performing impact prediction for changes that occur in the schema/structure of the data warehouse sources. We abstract Extract-Transform-Load (ETL) activities as queries and sequences of views. ETL activities and its sources are uniformly modeled as a graph that is annotated with policies for the management of evolution events. Given a change at an eleme...
متن کاملRule-Based Management of Schema Changes at ETL Sources
In this paper, we visit the problem of the management of inconsistencies emerging on ETL processes as results of evolution operations occurring at their sources. We abstract Extract-Transform-Load (ETL) activities as queries and sequences of views. ETL activities and its sources are uniformly modeled as a graph that is annotated with rules for the management of evolution events. Given a change ...
