Key-Value and Document Databases: When Each One Fits
Key-Value and Document Databases are two NoSQL models. One finds a value by its key, the other stores a whole JSON document you can query by any field. This post shows when each one fits and builds both patterns in SQL Server 2025 with a key-value table and the json data type.
Relational Database in Big Data: Still at the Center
The relational database in big data projects is still the system of record, and most analytics platforms copy their core business data from it. This post shows what a relational database does well, where it sits in a modern platform, and how the SQL Server 2025 json type adds a flexible schema next to ordinary tables.

ETL vs ELT: How Big Data Changed the Way We Load Data
ETL vs ELT comes down to when you transform: before the load on a separate engine, or after it inside the platform. This post compares the two and runs a small ELT pipeline in T-SQL on JSON orders.
Storing JSON in SQL Server
