Reducing Multidimensional Data experiments and discuss their results. Evaluating our solution implies executing different requests in various contexts: unreduced single fact table, unreduced relational star schema, reduced star schema or reduced snowflake schema. We show that queries are more efficiently calculated within a reduced star schema.作者: Indelible 時間: 2025-3-26 22:48

Problems with System Implementation Owing to changes in data sources, the content and the schema of a data warehouse may need to be changed for accurate decision making. Slowly changing dimensions and temporal data warehouses are the available solutions to manage changes in the content of the data warehouse. Multiversion data warehou作者: 情感脆弱 時間: 2025-3-30 07:07
