Azure Cosmos DB provides five APIs: Core (SQL) and MongoDB for document data, Gremlin for graph data, Azure Table, and Cassandra. Document stores are a bit more complex than key-value stores. Far too often I'm seeing "we're building for the web http://kkovacs.eu/cassandra-vs-mongodb-vs-couchdb-vs-redis, What I suggest is to find your best combination: If you're not familiar with MongoDB, here's a quick translation cheat sheet to get you familiar with the terminology.

Because it is simple to setup and use (installation is trivial: just copy the sqlite3 or sqlite3.exe executable to the target machine and run it) SQLite makes a good database engine for use in teaching SQL. If your app is dealing with a lot of JS Objects (with nesting) and you want to persist these objects then there is a very strong argument for using Mongo. This will return a Future.A DocumentSnapshot encapsulates all data inside an element from a collection. Now customize the name of a clipboard to store your clips.

A document’s schema is dynamic and self-describing, so you don’t need to first pre-define it in the database. MongoDB + Redis is perfect for document store It’ll have its quirks and general nastiness, just as everything else, as I’m sure you’ve already discovered if you really have been working on it already.

This is how you … This doesn’t provide any transaction abilities. Now one of the next steps will be providing a forum for our users. It is suitable for big data applications. That is one area I really think MongoDB fits for, but MySQL/PostgreSQL is more recommended in general. Entity Relationships in a Document Database at ZendCon 2012, Implementing CQRS and Event Sourcing with RavenDB, No public clipboards found for this slide. Most likely you will start writing processes or checks to keep your database consistent, which will probably not perform better than letting the RDBMS do it for you. I’ve seen at lot of companies are using MongoDB for realtime analytics from application logs. A document’s schema is dynamic and self-describing, so you don’t need to first pre-define it in the database.
