Selecting Online Data Warehouses

The purpose of online data warehouses is the centralization of data in a non-volatile, standardized system that is accessible to all relevant employees to make decisions. They serve as an historical archive of data and serve as a single source of truth, making it possible for users to compare data from different sources without having to rely on outdated data.

There are many aspects to take into account when choosing the right platform, architecture, and tools for a Data Warehouse. Should the warehouse, for instance be located on premises? Should it use extract, transform and load (ETL) or direct-to-database integration? How often should data be refreshed? How will the change data capture feature be used to capture and feed updates to the warehouse? In the end, choosing the appropriate technology should be based on an organization’s specific business use cases.

For instance, a bicycle manufacturer may use its data warehouse to discover more about the current customer behavior and trends. It may find that its customers are mostly women older than 50 and may be looking to learn more about the retail outlets they shop at for bicycles. This data could aid the company in improving its marketing and development strategies.

A team of IT professionals could make use of their data warehouse as a tool to aid auditing processes and regulatory compliance by providing historical records that can be reviewed. This can save a business time and money by removing duplicate information.
