Selecting Online Data Warehouses

The aim of online data warehouses is to consolidate data in a non-volatile standardized system that is accessible to all relevant employees to assist in making decisions. They function as an historical archive of information and a single source of truth providing users with the ability to compare data from various sources without relying outdated information.

There are a myriad of factors to be considered when choosing the appropriate platforms, architecture and tools for a Data Warehouse. Should the warehouse, for instance, be on-premises? Should it use extract, transform and load (ETL) or direct-to-database integration methods? How often should data be updated? What change data capture capabilities be used to collect updates and feed them into the warehouse? The organization’s business use cases should be the primary determinant in the selection of the best technology.

A bicycle manufacturer, for example can use its data storage facility to learn more about the actual customer preferences. It could discover that women over 50 comprise the majority of its customers and it may be interested in finding out more about the shops where these customers prefer to buy bicycles. This data could help the company improve its marketing and development strategies.

A group of IT professionals could use their data warehouse to assist auditing processes and regulatory compliance by providing historical records that can be reviewed. This could save the company valuable time and resources in these processes by avoiding unnecessary duplication of data.
