The blog post discusses the transition from SQL to JSON data modeling, highlighting the use of Hackolade, a tool that now supports Couchbase and assists in this process. The post reviews a manual modeling exercise involving shopping carts and social media users, illustrating how relationships in a relational database, typically represented via key/foreign key, can be translated into JSON through techniques like referential and denormalization. Hackolade aids in automating and visualizing this conversion, offering features such as reverse engineering from SQL server DDL files to JSON models, suggesting denormalization strategies, and allowing users to refine models by embedding arrays or sub-documents. The post emphasizes Hackolade's capabilities in generating dynamic models that can be shared and documented, enhancing the development and architecture of applications transitioning to NoSQL databases like Couchbase.
