Gone are the days of Excel spreadsheets.

What is a data warehouse?

A data warehouse is a large store of data from many sources within a business;  and typically, this data is obtained from day-to-day transactions within the organisation.  The warehouse transforms this mass of data into a single and organised system that is easy to analyse.

But isn’t that just like a database?

No, it is not to be confused with a database. A database is the raw data a company has acquired and a data warehouse is a type of database specifically designed for analysis. Therefore, a data warehouse is not simply a store of information but a system designed to summarise and analyse data in a format that guarantees insightful business decisions.

Why is a data warehouse necessary for your business?

Many businesses, your competitors included, use data warehouses to primarily organise mass data generated by their departments. Moreover, this accessible format permits the business to easily read data and summarize large quantities of information that would otherwise be misinterpreted or overlooked.  Simply this warehouse allows you to analyse your data quickly and pick up on any weaknesses and highlight successes in a format that is easily accessible.

What are the qualities of a good data warehouse?

  • Volume – it should contain a large quantity of data
  • Velocity – new data should be organised and optimised quickly
  • Variety – it should contain data from various different sources
  • Veracity – it should contain data that is solely accurate and ‘clean’
  • Value – the data should be trusted upon to make decisions
