Answer» Following are the disadvantages of using a data warehouse:- - Loading time of data resources is undervalued: We frequently underestimate the time it will take to gather, sanitize, and post data to the warehouse. Although some resources are in place to minimize the time and effort spent on the process, it may require a significant amount of the overall PRODUCTION time.
- Source system flaws that go unnoticed: After years of non-discovery, hidden flaws linked with the source networks that provide the data warehouse may be discovered. Some fields, for example, may accept NULLS when entering new property information, resulting in workers inputting INCOMPLETE property data, even if it was available and relevant.
- Homogenization of data: Data warehousing ALSO deals with data formats that are comparable across DIVERSE data sources. It's possible that some important data will be lost as a result.
