Bookmark or Share- Is there any NoSQL data store that is ACID compliant?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.
- How do you track record relations in NoSQL? - Stack OverflowIn NoSQL, you don't design your database based on the relationships between data entities. You design your database based on the queries you will run against it. Use the same criteria you would use to denormalize a relational database: if it's more important for data to have cohesion (think of values in a comma-separated list instead of a ...
- Is PostgreSQL a NoSQL database? - Stack Overflow"NoSQL" is a buzzword describing a diverse collection of database systems that focus on "semi-structured" data (that do not fit well into a tabular representation), sharding, and high concurrency at the expense of transactional integrity and consistency, the latter being among the basic tenets of relational database management systems (RDBMS).
- SQL versus noSQL (speed) - Stack OverflowPeople who tend to use noSQL use it specifically because it fits their use cases. Being divorced from normal RDBMS table relationships and constraints, as well as ACID-ity of data, it's very easy to make it run a lot faster. Consider Twitter, which uses NoSQL because a user only does very limited things on site, or one exactly - tweet.
- Transactions in NoSQL? - Stack OverflowYou can always use a NoSQL approach in a SQL DB. NoSQL seems to generally use "key/value data stores": you can always implement this in your preferred RDBMS and hence keep the good stuff like transactions, ACID properties, support from your friendly DBA, etc, while realising the NoSQL performance and flexibility benefits, e.g. via a table such as
