Data Warehousing (DW) is a common term used business intelligence (BI) projects and systems. The data warehouse has traditionally been the overhead, a large storeroom which aggregated and staged data from multiple sources into at single point. Analytics could then be conducted on this, and provide valuable insights for management.
Now, the problem with the data warehouse is that its huge, and expensive. The processes to populate the data warehouse consume large computing resources, and the outcomes after a lengthy project might be inaccurate or off-focus.
Within modern applications, and data analytics, we should consider analytics as part of an application’s design, performing smaller analytics projects on smaller datasets before engaging in larger ones. We should also consider incremental processing of data by actively managing data state in a similar way in which we manage application states.
This fits well with the Agile methodology.
So just like abandoned warehouse along the rivers and docks of modern cities, data warehouses will be abandoned with JIT Analytics, Agile BI, and better application designs.
