Consumable data delivery as a repository
With many legacy data engineering approaches, the output was just a report, then over the years the report needed to be used to drive decisions, and as a result, decision support systems (DSS) were developed with MOLAP (multidimensional online analytical processing), OLAP, and ROLAP (relational online analytical processing) data mart technologies in the backend. The days of PowerBuilder and Crystal Reports became the days of Cognos, Hyperion, Micro Strategies, SAS, Power BI, and many others. Even these Data Mart-centered architectures are considered legacy approaches today.
In the future, you will want to focus on the creation of a secure data mesh or data fabric as the delivery target for curated data. With these patterns, we overcome the data volume issues present in legacy DSS systems without sacrificing observable analytic query performance since exabytes of data just do not load into tools such as Power BI. This is an evident truth because...
