Introduction We mostly get inclined to use/introduce MongoDB for JSON storing/processing in our database system and Elasticsearch for searching operations in JSON data. However, what we often tend to overlook is that in reality, PostgreSQL can actually act as both NoSQL store and a powerful search engine too. It also comes with ACID guarantees, transactions, […]
There’s a new version of SQL Server released and we’re mainly an on-premises SQL Server shop. We’ve been using Integration Services (SSIS) for years now for all our ETL and data integration needs. With Microsoft’s focus on cloud (Azure and Fabric), does it make sense to upgrade our SSIS packages? Are there any new features?
There are a lot of tasks that DBAs and developers struggle to get done. These little things can be important, and perhaps AI can help us keep on top of them.
In this next installment, we look at using dbt to seed a Fabric Warehouse.
There’s not much to database keys, right? When you build a new table, you add a column to act as the primary key, then set it to auto-generate. Done. That’s all there is to know…right?
When working with an AI LLM, you have so much knowledge at your fingertips.
Introduction SQL Server 2025 introduced new features, including vectors. The main purpose of vectors is to create a new semantic search with the help of AI. Modern AI models represent text as vectors (embeddings) that capture semantic meaning. Similar meanings produce vectors that are close to each other in this vector space, allowing AI systems to […]
Parallelism can reduce concurrency. This is a strong reason not to allow SQL Server to execute queries aggressively in parallel mode. In this tip, I will set up a demo to show that parallelism reduces query performance on a server with high concurrency.
