Does CouchDB use SQL? No. So it may be mentioned in a post about "NoSQL".
> Description of Cassandra is misleading.
Defend your claim.
> He also misses the fact that Cabinet has real master-to-master replication.
When you start to need real master-to-master replication, the kind that Tokyo Tyrant offer is simply insufficient. It has no versioning, no way to resolve inconsistencies, no quorum write/read, etc. By the time you're at that scale, you had better be looking at Cassandra, HBase, or Hypertable IMO.
> Feature overlap between Redis, Cassandra and Tokyo C/T is too big.
Maybe I can buy that Redis and Tokyo Cabinet/Tyrant have too great of feature overlap (and note that I'm only interested in Redis as a high performance count server), but Cassandra is in a completely different realm with completely different sets of tradeoffs. To suggest that it is similar to the others is simply naive.
- lucifer 17y agoCouchDB is a document centric system. Its really a different beast, altogether. Its closer to a CMS than a DB.
- jbellis 17y agoNo. While you could build a CMS with couchdb, it definitely isn't one out of the box. All "document-oriented" means in the Couch context is that the db's data model is "you have a key and a collection of attributes associated with it."

- jbellis 17y agoYou're confusing "Notes Domino" with "a CMS" which it is not. From your link: > CouchDB shares a basic concept of a document oriented database with views that Notes Domino has. > In this model "documents" are just arbitrary collections of values that are stored some how. In CouchDB the documents are JSON objects of arbitrary complexity. In Notes the values are simple name value pairs, where the values can be strings, numbers, dates or arrays of those.
- lucifer 17y agoI didn't say it was a CMS: "Its closer to a CMS than a DB."
- paulgb 17y agoI guess the name CouchCMS was already taken?
