On Three Major Holes in Data Warehousing Today
نویسنده
چکیده
During the past several years, many enterprises have created data warehouses (and data marts) in order to run applications. Data warehousing technologies used have been primarily extract-transform-load (ETL) tools, database modeling and design tools, and relational database (RDB) systems. There are three major holes in data warehousing today. These include inadequate attention to dirty data, inadequate performance and scalability in supporting scan-oriented operations, and inadequate selection of source data to load into the data warehouse. In this article, these three problematic areas are explored and approaches to addressing them are outlined.
