Donde viven los datos. Se dividen entre sistemas relacionales, que imponen un esquema y responden en SQL, y almacenes NoSQL y vectoriales, que cambian esa estructura por flexibilidad o por búsqueda por similitud. El tema SQL de Lenguajes y frameworks trata el lenguaje de consulta; esta área trata los motores que lo ejecutan.
Las bases de datos relacionales con las que he trabajado durante más de 20 años, y los almacenes documentales y vectoriales que he añadido para aplicaciones en la nube y flujos de IA.

It has been a little while since I last played around with a NoSQL database on the blog. Back in 2014, I wrote a few posts about CouchDB and over the years, I have done a bit with Firebase. Today’s topic is going to be MongoDB.

I was playing around with consumption of a CouchDB JSON feed when I received the familiar “Cross-Origin Request Blocked” error. The question is, “How do you enable CORS in CouchDB?” If you open the ‘Configuration’ tool, you will find ‘enable_c…
So, you just created a CouchDB database, added a user to it, and want access to be limited to that user? There is a simple way of doing this. Let’s use a previous example, for this demo. As you can see below, by default, you do not need to be authenticated, in order to interact…
If you are like me, you probably have not had much of a reason to use NoSQL but you have been interested in it. I recently decided to check out CouchDB. CouchDB is an Apache project that was created in 2005 by Damien Katz. CouchDB is interesting in that it stores your data with…
Database normalization is a process meant to reduce or eliminate data redundancy. Typically, a normalized database exists in first normal form (1NF), second normal form (2NF), or third normal form (3NF). First Normal Form In order for a database to be in first normal form, your…
