The term serverless is somewhat misleading because servers obviously exist somewhere. This is not magic. For decades, deploying a database meant answering impossible questions. How much capacity do you need?…
Most introductions to dimensional modeling start with the star schema – a single fact table surrounded by dimensions. It’s clean, simple, and perfect for explaining the basics. But real businesses…
You don’t need to understand the origin stories of why technology works the way it does. But we stand on the shoulders of giants that dedicated their time to solving…
If you’ve ever worked with a data warehouse or business intelligence tool, then you’ve probably encountered a star schema. If you haven’t, then you might want to look into it……
In the late 1990s and early 2000s, the rapid growth of the web changed database design forever. Traditional monolithic, single-node relational databases, the backbone of enterprise applications for decades suddenly…
This form of clustering removes the need for Z-Ordering and partitioning, thus simplifying database layouts and increasing query performance. Databricks actually quotes 10x query performance gains using this approach, so…
Not only does it sound cool, but a vector database is a specialized type of database designed to store, index, and search high-dimensional vectors. These are numerical representations of data…
When you index data you don’t often think “I wonder where all this data physically resides”. Or maybe you do, but anyway, when working with massive datasets, even the smartest…
In the vast landscape of data engineering and computational systems, Directed Acyclic Graphs (DAGs) quietly orchestrate the flow of tasks, computations, and dependencies. From compiler optimizations to machine learning pipelines,…
When storing and retrieving large volumes of ordered data, the goal is to keep search, insert, and delete operations efficient while staying balanced. B‑trees (Balanced Trees) do exactly this: maintain…
Everything is obvious once you know the answer. The paperclip looks simple only because someone else did the hard work to invent it. The same applies to the Entity Relationship…
Data is not just the new oil; it’s the new language of decision-making. But before machine learning, embeddings, or even NoSQL, data had to be structured, described, and designed. Understanding…
