@dan_nanni: Databases are not defined by brand names but by how they organize data and optimize trade-offs. Different systems prioritize different goals: strict consistency and complex queries, massive horizontal scale, ultra-low latency access, high-throughput analytics, relationship traversal, or semantic similarity search. The result is a spectrum where no single database is “best” overall—each is engineered around a dominant access pattern, workload shape, and performance constraint. Choosing a database is therefore less about popularity and more about matching data model and query behavior to the problem you are solving. Here are different types of databases 😎👆 Find a high-res pdf book with all my technology related infographics from https://study-notes.org #dev #softwareengineer #database #databasemanagement #devops
