Reading Time: 4 minutesSoftware systems designers often structure their thinking around the underlying functional and data/information components of their desired applications. This approach—analogous to the scientific method of breaking a system into its smallest sub-parts in order to understand how it works—forms the…
Reading Time: 5 minutesIn my previous post, I described the data fabric architectural pattern. Before turning to the data lakehouse, let’s first look at what I mean by an architectural pattern. The Power of a Pattern An architectural pattern, or logical architecture, describes…
Reading Time: 4 minutesSince its first incarnation almost 35 years ago in my IBM Systems Journal article, the data warehouse (DW) has remained a key architectural pattern for decision-making support. By decision-making support, I mean everything from simple reporting and querying to AI-based…
Reading Time: 3 minutesIf you are in the data management world, you probably help your company to redefine its data analytics architecture, especially in the context of cloud adoption. At some point in the process, someone might have stared at the myriad boxes…
