Data warehousing is used to catalog and record data for reporting and analysis by unifying all departmental databases into one schema. Enterprise resource planning (erp) software on the other hand heavily rely on integrated data for automation and efficiency of operations in an organization. When an organization therefore has a data warehouse, its erp operations will be more efficient and speedy as compared to one that uses redundant data from different departments. The benefits of data warehousing are as follows:
A data warehouse contains all departmental data in one location. With this kind of schema, all information about the whole organization is in one common place and it is easy to retrieve it. Executives can also make very quick and timely data reports that will be important in the organizational decision making.
Before data is loaded into the data warehouse, it undergoes certain processes where it is cleaned and refined. Data redundancy is removed such that not two similar data sets will be loaded into the data warehouse.This is important in an erp environment since the automation software will not have any redundancy in it. It also saves on the premise hardware that would have otherwise been used in saving redundant data.
Information in a data warehouse is independent from the organizational operating system. It is saved separately and so even if there was a data purge or accident, information would still be easily retrieved from the data warehouse. This is important for erp data consistency.
