NoSQL database systems are often highly optimized for retrieval and appending operations and often offer little functionality beyond record storage (e.g. key-value stores). The reduced run-time flexibility compared to full SQL systems is compensated by marked gains in scalability and performance for certain data models.

Apr 9, 2010 · Document-based NoSQL databases (e.g. MongoDB, CouchDB); Key/Value NoSQL databases (e.g. Redis); Column family NoSQL databases (e.g. Hibase, Cassandra). What we call an Aggregate here, is what Eric Evans defined in its Domain-Driven Design as a self-sufficient of Entities and Value-Objects in a given Bounded Context.

Aug 13, 2013 · NoSQL products support a whole range of new data types, and this is a major area of innovation in NoSQL. We have: column-oriented, graph, advanced data structures, document-oriented, and key-value. Complex objects can be easily stored without a lot of mapping.

Sep 15, 2010 · NoSQL is a database system where data is organized into the document (MongoDB), key-value pair (MemCache, Redis), and graph structure form(Neo4J). Maybe there are possible questions and answer for "When to go for NoSQL":

Oct 29, 2018 · Traditionally, NoSQL was used for unstructured high volumes like logging results, website search data etc. However, with professionals becoming more comfortable with document storage and relational capabilities improved over time, NoSQL is often favoured over traditional relational databases.

I am learning nosql and would like to understand how data should be modeled. In a typical relational database for an CMS application, for example, you may have two tables: article and author, where article have an reference to the author. In nosql system, you may create an article document this way since they are just disguised object graph

Apr 21, 2010 · NoSQL solutions usually manage relatively limited schemas with large cardinality in few entities, while data warehouses typically have lots of facts and dimensions (in a dimensional model) or lots of entities in a 3NF model.

So ignore the fact that we should just use a NoSQL DB - client infrastructure requirements are getting the way. We have data that obviously belongs in a non-relational model, but we have to use SQL Server 2014 for persistence. Is there a way to use the library for something like RavenDB or MongoDB with SQL Server for persistence?

Sep 17, 2010 · Most of the NoSQL solutions I've seen seem to fall in the key-value store approach, and aren't relational. They tend to give up ACID properties. So when you evaluate a database system, when you don't need ACID, when you don't want relational algebra, when you do have a need for a KV store, then the NoSQL approach is your friend.

Apr 22, 2009 · Is there a (roughly) SQL or XQuery-like language for querying JSON? I'm thinking of very small datasets that map nicely to JSON where it would be nice to easily answer queries such as "what are al...
